  2. Thanks for being precise about Machine Learning. There's way too much BS floating around on that field. The reinforcement learning approach seems like another decent tool in the box to takle a very difficult problem. Honestly that's more than anyone can ask for, imho.

  3. Hardware security is a field which is not in lime light and many people are unaware about it. Thanks for highlighting this.

  4. My Father used to work for GEC when they were making the first germanium transistors. He said they would use car headlamps as a heat source to attach the legs to the Germanium wafer. He kept a load of the prototypes that had exceptionally high gain.......I tested some the other day and they are still good 69 years later.

  5. It's been said by economist and data scientist Vaclav Smil that manufacturing is the base for everything else. Another study has found that above a certain finance to GDP ratio (and the USA is well above this, as is Hong Kong), finance actually hurts the economy. "Liquidity" that disappears during stressful times, which is modern finance, is parasitic and does more harm than help. At one point 33% to 50% of Princeton engineers ended up working on Wall Street.

  6. Love the new imperial units. Currency: fractions of 1 Messi contract at Barcelona. Electricity: fractions/multiples of 1 WalMart.

  7. Incredibly good eye/ear opener! If you contrast HK with Singapore, the highlights are even clearer. I highly recommend this video and of course, this channel.

  8. You should do a special video on just keeping the air clean inside a fab. Everything for the building envelope to the HVAC equipment. These places are thousands of times cleaner than any operating room

  9. These bags are unreasonably expensive. In 2007 my wife and I went to France for vacation. We stop by LV store, she spent $6000 for TWO bags!!??? 15 yrs pasted and these 2 bags are still in her our safe in the bank. In a box, in a bag in another bag, for each bag. Never used. I do not understand.

  10. As someone who's been following chip lithography for close to 3 decades: The next step is always "a major crisis". This started already in the early to mid 90s. And I think "we" learned from EUV to not put it off. That EUV was delayed by a decade just got the fabs to become insanely good at multi patterning. TSMCs N7 was an absolute bonkers smash-hit. It's only downside was that the hundreds of patterns made lead times enormously long. N6 uses DUV for almost everything, but has two critical layers moved to EUV. This, besides the small logic shrink, made it absurdly cost effective, and is the reason why AMD likes to do everything possible on N6. EUV vs High NA-EUV will probably be the same: They will figure out how to make sure they only use it for one or two layers in the beginning. If that's the action plan, then maybe a polarizing filter is financially viable.

  11. Can’t believe I randomly decided to check Asianometry only to find out he had uploaded 8 seconds before. So much win!

  12. Very, very nice video. Speaking of the military, I recommend you do a video about the "Three Heavies" (Mitsubishi Heavy Industries, Kawasaki Heavy Industries and Fuji Heavy Industries aka Subaru) and their very important relationship with Boeing. I don't hear many people talking about that.

  13. I'm intimately familiar with this topic because I was an early adapter of DLP projectors for home theater use. 1-chip DLP has a serious flaw, in that, at any given moment, there is only one of the primary color being projected onto the entire screen. Some people are much more sensitive to the so called "rainbow effect." Moving your head quickly can exacerbate the issue. They reduced the problem by either spinning the RGB wheel faster, or doubling up the colors into RGBRGB wheel, so that one color stays on the screen for a shorter amount of time, each. Technically, even 3-chip DLP will have many pixels displaying just one color at some moments, but these are per-pixel effect, not whole screen effects. Fundamentally, what is projected onto the screen is a pulse-code-modulation pixels. Each pixel is either ON or OFF at any given time, and in case of 1-chip DLP, in one of the Red/Green/Blue. There is no grayscale. It's just ON or OFF. Each pixels blinks at incredibly fast rate, you can't normally tell, and the brightness is controlled by the rate of ON time, vs. OFF time (hence PCM). For example, 50% brightness would be represented as ON/OFF/ON/OFF/ON/OFF and so on. 1/3 brightness would be ON/OFF/OFF/ON/OFF/OFF, although they could throw in some randomness to making it look more natural to human brains.

  14. I am a lecturer in electrical engineering from Thailand. In recent years, I have been in contact with colleagues and students from India. They are very motivated and passionate about high tech industries. I think that India will have a bright future with a lot of young people who are willing to study difficult subjects and to work in areas where STEM education is required. You are right about the hard disk drive industry in Thailand. No significant tech transfer took place here. We just deliver manufacturing service. Regarding semiconductor design, we do have a leading fabless company specialized in HF RFID and NFC in Thailand. The company name is Silicon Craft Technology. You might want to make a video clip about this interesting company in the future. Thank you for the great contents. I am involved in a discussion on the national level regarding expansion of the semiconductor and smart electronic industries in Thailand. Your contents provide very useful information for the development plan.

  15. This is by far the most interesting, obscure tech history video you've ever made. I asked my Bulgarian friend if he knew any of this and he said that his grandpa did something in electronics back in the communist times but he didn't really know the details. When I forwarded him the video, he was absolutely shocked. Apparently, young Bulgarians don't know any of this stuff meaning it never got ingrained in the zeitgeist like coal mining is to West Virginia (which has practically no coal miners) or Detroit and cars.

  16. As someone who grew up in Japan, hearing the rice cake saying was just amazing. The lack of research is what makes 99% of youtube channels trash - you are in the 1% my good sir. Thanks for the amazing video essays as always, love to hear about the industry as both my parents work at tech companies in Japan 🇯🇵

  17. Jon, I have to say thanks for your in-depth coverage and even more so for keeping your graphs onscreen to give me enough time to smash the pause button. Too many creators flash a graph up for 3 seconds and assume the viewer is completely au fait with the narrative.

  18. It is interesting how India's north western states like Punjab, Haryana suffers largely from the same issues. Over draining of ground waters and dependence on Rice and Wheat.
    238
  19. This channel is super-informative. Even though I work at imec and go there every day, like 80% of what he said was news to me! You are amazing Asianometry! Keep up the great work.
    237
  20. I came for semi conductor tech but stayed for the well researched and delivered multitude of topics.... So the silicon bule analogy was welcome.

  21. A largely automated present-day container ship can carry more tons than the merchant fleet of an entire early modern kingdom. In 1582, the English merchant fleet had a total carrying capacity of 68,000 tons and required about 16,000 sailors. The container ship OOCL Hong Kong, christened in 2017, can carry some 200,000 tons while requiring a crew of only 22. Source: Yuval Noah Harari, Financial Times

  22. a forecast of a decade, based on a few years data, just to fit sales targets.. is now, more than legendary. Mythological as it were. Amazing. Thanks Jon. Really interesting stuff.
    233
  23. Always blown away by the research and numbers here. Would love to get some insight on the research process behind these videos
    231
  24. Another emerging application of MEMS is in all-optical field programmable photonics gate array (FPPGA). It is basically an FPGA for photonics integrated circuit (PIC). The PIC (and silicon photonics, as this is the most potential candidate for the platform) itself is already dubbed as post-moore technology so knowing researchers trying to build this technology is very exciting. Major project like H2020 MORPHIC has made significant result to realize this technology. PS: Photonics Research Group from U Ghent has a YouTube channel to spread their latest update on their works. Their explanation videos on FPPGAs are easily digestible and quite fun to watch.

  25. I haven't been in the hardware business since about 1996. In some ways, the changes seem almost trivial; I remember discussions of stacking bare silicon chips, heat dissipation, packaging, interconnects, etc, but we were a board-level company, so it was all just poorly-informed guesswork. These discussions are fascinating in their details.

  26. The electron gun assembly in the diagram is backwards. The pins connect to the TV's circuit board.

  27. This channel is so good.

  28. So much to say after watching this, so sad that Dr Wang’s dying wish was for his company to be remembered and honored for being founded by an immigrant, I looked up his name at the Computer History Museum in Mountain View and they have hardly anything about him. wang should be better remembered. sadly very few people remember this company and even less know it’s founder, even though they went toe to toe with IBM. one other interesting note besides the invention of core memory, Wang invented the SIMM. incredible work on this video, as always your videos are so rich with details and nuanced history. I’m blown away. The anecdotes you mention about An Wang, his early history, all the pictures of products, I can’t heap enough praise. The story about John Cunningham is quite sad too, he is not remembered at all and sadly passed away in 2013. just a sad story all around. I want wait for this video to be public so I can share it. this story needs to be known.

  29. I worked in crystal manufacturing. I saw a lot broken necks. This mostly happens when the finished crystal is ready to put out of the oven. In fact it happens while it gets put out. The crystal swings out of the oven. And the shear force does its job. Then you have to clean the whole machine because parts of the crystal fall in 1000 pieces. Which sometimes damage the glas crucible. Which isn’t so bad. It’s not reusable anyway. But the oven itself can get damaged. If everything works, the neck will be cut by pliers.
    227
  30. In the mid 80's I worked at a silicon design firm. Mostly 3 micron gate arrays. My boss and a really sharp engineer from the client company designed a modem chip. Their first silicon worked fine which elevated them past hero status to God of silicon design status. Mixed signal chip design is something like witchcraft. Thanks for another great video!
    225
  31. I've never heard DRAM pronounced as "DRAM" before. Always as "D-RAM". Probably to denote the difference between DRAM and SRAM, or Static RAM,
    225
  32. As a pre-SQL programmer, SQL was a game changer. Using SQL gave me a logical, abstract view of the data structure, significantly reduced my design and coding time, and allowed changes to the database structure without having to break code or migrate data. I used several systems on PCs like DBase and Firefox which had SQL database at their core. Also need to remember that systems back then were so constrained by CPU performance, memory storage, and disk capacity that SQL would have been too large to run on some of the early computers. Great video as always!

  33. Hey Jon, I'm pushing TSMC to have a fab tour (hopefully fab 18) after computex next year. They're slow to open up, but there's hope. I'll push for you to be added to the list if it goes ahead.

  34. As an Indian who is neutral about Pakistan, this video was educative. This should be a wake up call for India too. Contrary to what most people think, the farming methods here are not that different. Stubble burning in Punjab causes Delhi to become a gas chamber every year. Sometimes, a neutral viewpoint is necessary to see things in the correct perspective and take remedial action wherever necessary.
    219
  35. Great video Jon! Thanks for the mention. Thought you did a good job on framing the open source tools and the aims.

  36. I'm curious why a mix of rock and sand isn't used. As a mining engineer in Australia. We could send them untold volumes of NAF (Non Acid Forming) crushed waste rock from any number of mines in whatever size they want for penny's on the $$. I mean, presently it's just being dumped on the waste rock pile. It's already blasted and stockpiled. It literally has no value here. In fact it represents a significant cost to keep expanding the waste rock dump. Thus if someone wanted to pay transport it would represent a cost saving here. Would surly reduce the volume of sand required and provide a more stable foundation it a blend was used.
    216
  37. I developed optical ICs and simulators 27 years ago. Glad to see that the market has finally moved ahead to use the technology. Now the need has increased sufficiently to justify production development. Applications include LIDAR and high speed optical communications. The need will not be as high as other technologies but the volume will be enough to employ quite enough engineers.
    215
  38. In the 80s, US embargo, Chinese embargo, and collective farming was a nightmare. I was hungry all the time.
    214
  39. This hurt to watch as a Filipino. Sucks, and I do hope we can finally revive our industries here with competent leadership…someday.

  40. Hubei and Hebei are different provinces. Their pronunciation is slightly different. I owild reccomemd rerecording the audio to fix this.

  41. Whilst recycled water didn't catch on in most places in Australia it did end up being used in Perth the capital of Western Australia. The main reason it succeeded there was thanks to a large public information campaign to properly inform the public of how it works and why it's needed.

  42. This made me sad. As a Chinese American who also a Shanghainese, Wang's story is so typical and relatable to many Asian families. The first generation experienced war and hardship, came to the US and worked extremely hard to build up a successful family foundation. I remember hearing my parents talking about Wang labs when they were poor graduate studentsin America. I'm also old enough to grow up poor in China and struggled along side my parents. Forged in hardship, my parents were frugal and shrewed, built up several million in 30 years, and I am successful enough to expand it further. Yet, unlike us, my children are born relatively wealthy, never known hardship. Listening to Wang's story strengthens my worry that their lack the 吃苦奋斗 spirit would eventually undo the labor of two generations. Wang's story illustrates the old Chinese saying 富不过三代, and shows a major flaw of Asian family traditions.

  43. Harder, better, faster, stronger. Can't believe they split.

  44. I know it sucks when your video doesn't seem to get appreciated by the masses, but you're doing great work here. There are a thousand economic/tech history channels. What you put out with these is unique. Perhaps consider making these for a separate channel, or make a series?
    208
  45. The obvious flaw with comparing TSMC's RnD spending with Intel's is that Intel also designs a plethora of chips and software solutions. TMCS only has lithography, packaging and PDK development. Intel also has these on top of everything else. Alphabet and Meta seems to spend money on a lot of useless things "just in case it sticks".
    208
  46. I feel like you're the only channel I know that can get me really engaged in this kind of stuff without dumbing it down to the point where I'm hardly even learning anything. Really exciting tech to see. Thanks for the vid!
    207
  47. i love how your sense of humor is so deadpan that it is barely discernable, yet beneath the surface lies some of the most maniacal hatred i have ever heard
    206
  48. This is absolutely fascinating. Like you said it's amazing to see all these companies that are competitors all getting together to make a massive change in their whole industry happen time and again, a process that cycled until the turn of the millennium
    204
  49. Maybe a video about Zeiss could be interesting as well.
    202
  50. Thanks Jon, as usual a brilliantly researched topic. As another commenter stated "Niche is good". In the years to come, you will be regarded as the definative semiconductor historian.
