In an interview given to the Computer History Museum, a former government of the Taiwan Semiconductor Manufacturing Company (TSMC) shared his expertise of working with the corporate from its earlier years to right on the time that TSMC grew to become one of many dominant chipmakers globally. Dr. Chiang Shang-Yi spent a long time on the Taiwanese chipmaker and through this time he oversaw TSMC’s analysis and growth efforts and labored with the corporate’s founder Dr. Morris Chang. During his profession within the semiconductor trade, the previous government additionally noticed some controversy when he left TSMC to affix China’s Semiconductor Manufacturing International Corporation (SMIC) which was his final chip firm earlier than retirement.

Former TSMC Executive Calls Joining SMIC One Of His Biggest Mistakes In Life

Dr. Chiang got here into the highlight in 2020, when its co-CEO Mong-Song Liang introduced a shock resignation after the previous was appointed as vice chairman. The CEO despatched a strongly worded letter to SMIC’s administration however remained within the firm and SMIC’s regulatory filings revealed that the corporate had additionally purchased him a housing unit. Dr. Chiang left the corporate final yr advert throughout his time on the firm he repeatedly harassed the significance of superior packaging and provide chain as essential for SMIC’s future.

His interview covers his time at TSMC, and his ideas on Intel Corporation, which on the time was main the chipmaking race. Dr. Chiang remembers telling colleagues how Intel’s applied sciences have been generations forward of TSMC’s and shared that it was his want that TSMC would outpace the American firm’s expertise whereas he was on the firm.

Sharing the variations between Intel and TSMC on the time he said:

Intel, not TSMC, had a pair completely different cultures. Intel determined they wish to do all the pieces, “copy exact”. This most essential precept of their R&D and their manufacturing. And what it means it is nice for them. What it means, they develop this expertise in R&D, use this gear, use this recipe. They examine all the pieces very totally. Everything nice. Go to manufacturing, you by no means change it. You simply comply with that. Don’t do any change. It’s nice. You have a lot decrease danger. But the one downside is a yr later, the brand new gear has a greater effectivity. TSMC will adapt that, Intel wouldn’t. So, then TSMC would start to have a decrease value than Intel. So, TSMC tried to be very versatile, which it tailored.

And one motive is, apparent motive is Intel’s system. They can promote the wafer for $20,000 a wafer, as a result of their CPU chip’s very excessive value. And TSMC can not promote the wafer for $20,000. We can solely promote for $4,000. And we have now to attempt to reduce the price. Next factor is Intel– I actually respect Intel. I feel they’re most keen to take very excessive dangers. In each era, they’re keen to take danger to do one thing new. And in lots of key areas, for instance, like high-Ok steel gate, strained engineering, FinFET, and many others., it was all the time Intel, the primary one to adapt that. And then TSMC would adapt within the subsequent following era.

So, each node, Intel’s efficiency was higher than TSMC. When I used to be at TSMC, I maintain telling individuals, “We are behind Intel.” We have been behind Intel. “Don’t take a look at it you can launch your 10-nanometer earlier than Intel, then you definately’re very glad. you’re positively fallacious. Number one, TSMC’s 10-nanometer definition is extra like Intel’s 14-nanometer dimension

Intel’s Performance-Driven Culture Ensured Its Edge Over TSMC Says Dr. Chiang

He additionally shared that in his time at TSMC, he began a mission aiming to beat Intel’s transistor management however ended up failing which is without doubt one of the largest regrets of his profession.

The mission remained secretive inside TSMC, and Dr. Chiang shared that:

TSMC often will wait till Intel tailored, until do it on the subsequent following era. Number three, not solely the design rule, TSMC was additionally behind in transistor efficiency. TSMC all the time behind Intel’s transistor efficiency. And that is a superb motive as a result of Intel, their solely product is CPU. And that’s efficiency pushed – they want that. TSMC would not want that. But often if you happen to attempt to decide who has a greater expertise, you go by efficiency. And you needed to respect Intel had the higher efficiency. When I used to be at TSMC, it was my final couple of years, I begin an initiative. I say, “I want–” we referred to as it Advanced Transistor Leadership, “We want to catch up and beat Intel in transistor performance.” And that mission failed. That mission failed. I feel no one outdoors of TSMC’s small group knew about that. So, certainly one of my largest regrets in my whole profession is we did not meet up with Intel. But in my thoughts, TSMC expertise was behind Intel. While you take a look at it from the floor, TSMC now is ready to do 5-nanometer manufacturing. Intel’s nonetheless at 10-nanometer. But I feel Intel did stumble by some means. Right now, I feel, Intel actually is somewhat bit behind.

After leaving TSMC, the manager went on to affix SMIC, when the corporate’s CEO – who had additionally labored at TSMC – turned out to be a detailed colleague and a household good friend. Dr. Chiang sought permission from Dr. Chang, which was granted and he joined SMIC. However, switching to the Chinese firm was one other remorse, with him outlining that:

Later on, I joined the corporate. It was a mistake. Yeah. You did one thing right. You do one thing silly in your life. It was one of many silly issues I’ve performed.

TSMC Executive Remembers Working Long Hours – Cites Depreciation As Reason For Company’s Success

The variations within the working tradition between the U.S. and Taiwan have additionally been a scorching level of debate within the trade as of late as TSMC is constructing its largest chip plant in Arizona. These variations have repeatedly been cited by Dr. Chang, who believes that the strict working tradition in Taiwan is without doubt one of the key causes behind TSMC’s success.

Dr. Chiang additionally touched upon these variations, and he shared that fabs in Taiwan used to run full time as a result of:

So, I firmly imagine this is without doubt one of the actually essential the explanation why TSMC succeeded. It’s tradition. If gear went down, as a result of gear depreciation value was so excessive, you actually wish to run your gear 24 hours a day. In United States, if gear went down, wait till subsequent morning. The individuals are available at eight o’clock and doubtless go to repair it, 9 o’clock. Yeah. But if at two o’clock within the morning, we simply referred to as the gear engineer, “You come right away,” he will not complain. And his spouse will not complain. And that is the best way it’s.

He additionally recalled working lengthy hours and weekends at TSMC in Taiwan, whereas his household was in the usas executives who had held his job beforehand have been constantly modified as a result of a scarcity of outcomes. Dr. Chiang recalled that:

I joined the corporate I feel on June– July sixth, and I labored all day, all evening, each weekend, Saturday and Sunday. I stay within the dormitory within the Science Park a few couple hundred meters from the workplace. I seldom left the Science Park besides go to get a haircut, purchase some groceries. I labored days, nights, weekends, holidays. The first time I went mountain climbing with my mates was October twenty fifth. It was a nationwide vacation at the moment, so for 3-1/2 months I labored day-after-day and each evening. Because at the moment, they have been creating .25 micron expertise. And through the .25 micron expertise growth, they modified 4 R&D VP’s. I used to be quantity 4. And they modified three program managers and I used to be the final one to wash up. We had recognized 5 main technical issues which wanted to be resolved. And truthfully, I did take some benefit of the information I already discovered to assist remedy some technical issues.

He additionally revealed what it was like working with Dr. Chang, revealing that Dr. Chang would solely give subordinates half-hour to current their concepts. During this time, he would concentrate on details he didn’t know, and if he was unimpressed through the first 5 minutes, then he would spend the following 25 criticizing the presenter.

Dr. Chiang discovered a workaround, which he defined as:

He completely has no endurance for this kind of factor. So, it’s important to go reverse route. You inform him, “This is the result.” Then he says, “Oh.” Then he thinks, “My 30 minutes already paid off.” Then he will probably be very affected person to take heed to you on the small print.

Once Dr. Chang’s consideration was caught, he could be “even very nice to you” stated Dr. Chiang, and likewise be”very, very patient. Because his 30 minutes already paid off. He already got what he wanted.”

Since Dr. Chiang’s departure, TSMC has established itself as one of many world’s largest chipmakers and it’s competing neck to neck with Intel. The firm is presently racing to roll out its 3-nanometer semiconductor manufacturing expertise to mass manufacturing, because it competes with each Intel and Samsung for the high-end chipmaking expertise crown.
