During his seventeen years in TSMC, he has done a great job. Why is this the end?

In 2003, TSMC beat IBM with its own technology, and it became famous in the world of the 130-nanometer "copper process". The Executive Yuan praised the TSMC R&D team. At that time, Liang Mengsong, who was in charge of advanced modules, ranked second, and the credit was second only to senior vice president of research and development, Jiang Shangyi.

The complaint filed by TSMC clearly stated the importance of Liang Mengsong and said that he “responsible for or participates in the most advanced technology of each generation of TSMC's process.” Liang Mengsong is also the inventor of nearly 500 patents of TSMC, far more than other supervisors. Member of the "New Process Equipment Selection Committee".

Liang Mengsong's breadth and depth of TSMC's advanced processes, as well as familiarity from R&D to manufacturing integration, are among the few in the company. "When he went to Samsung, even if he did not actively leak TSMC secrets, as long as Samsung chose the technical direction, Liang Mengsong reminded that in this direction you don't have to leave, they can spend a lot of material and time," said Tai Shuhua, chief of law at TSMC. "He is really special," Fang Shuhua stressed again.

Even the current FinFET technology that TSMC and Samsung are fiercely competing for is actually one of Liang Mengsong's strengths. TSMC’s complaint specifically emphasized that “Liang Mengsong is deeply involved in the R&D of TSMC’s process and is the inventor of related patents.”

This is not surprising. Liang Mengsong’s teacher and doctoral supervisor is Professor Hu Zhengming, a well-known FinFET inventor who was the chief of TSMC’s technology.

Their teachers and students have a lot of feelings and have been in contact for many years, but there has also been an episode.

In 2009, Hu Zhengming's wife prepared her husband's birthday and sent an email to the students. It was discovered that the Liang Mengsong address in the group was actually "". This email was later submitted to TSMC as an exhibit. This proves that before the end of the ban on the competition of Liang Mengsong, he worked at Samsung.

Liang Mengsong is unrecognized in the semiconductor industry. It is different from the R&D technical talents. Most of them are low-key. However, after Liang Mengsong was crowned with the name of "TSMC Rebel", he was destined to be a historically named person. It was only from TSMC that he turned to Samsung Electronics. The technology madman, it seems that it will once again appear in the semiconductor industry rising in the mainland storm, which will be a shocking bomb in Taiwan, the mainland and South Korea! Let's take a look at the related content with Xiaobian.

Seeing this, I believe that readers can't help but wonder, how can such a powerful person leave TSMC?

Liang Mengsong has a "heart knot" from Sun Yuancheng, the current technical director of TSMC.

The two are close to each other, and they have been promoted in the same way. They have also been elected as academicians of the International Institute of Electrical and Electronics (IEEE).

Jiang Shangyi, who has been at the helm for many years, retired in 2006. Because TSMC's R&D organization is growing, the plan is to share the responsibility of the chief of technology with two R&D vice presidents in the form of “Two in a Box”. One is from Luo Weiren, who is from Intel and has a high score.

"I believe that he has considerable expectations. When I leave, he will be one of them (the vice president of research and development)," said Jiang Shangyi, the current advisor to TSMC's chairman. But in the end, Sun Yuancheng was promoted and Liang Mengsong became a subordinate of Luo Weiren.

His dissatisfaction is overwhelming, and a research and development supervisor at the front desk is looking at his eyes. "I think he always has a little complexion."

After leaving the TSMC in February 2009, Liang Mengsong taught at the Sungkyunkwan in South Korea to go through the water and then hopped to Samsung. Samsung’s strength in the semiconductor industry is that TSMC is in line with Intel’s “800-pound gorilla”. TSMC is of course immediately offering false punishments. Liang Mengsong has also won the most famous “in the history of Taiwan’s semiconductor industry”. Rebel" title.

There are so many people in the semiconductor industry to quit, and the number of defendants is countless. It can cause such a big storm. It is obvious that Liang Mengsong is not a leisurely generation.

In order to sue Liang Mengsong, TSMC commissioned a third-party professional organization to compare the process technologies of TSMC, Samsung, and IBM for nearly four generations. It was found that Samsung’s technology should be derived from IBM pedigree and should not be the same number as TSMC. However, the comparison found that after Samsung was 45 nanometers, the process began to be closer to TSMC.

The most crucial battle between TSMC and Samsung is Apple's A9 processor battle. The original Apple chip is Samsung's unique business. TSMC gradually replaced Samsung as one of the suppliers. However, on the A9 processor generation, Samsung's 14nm FinFET. In advance, and won the Qualcomm big single, let TSMC's 16nm FinFET first defeat, and let TSMC maintain 70% market share for 28 consecutive years, no advanced process can surpass 28 Nano achievements.

These above-mentioned achievements are all irrelevant to Liang Mengsong. This is why TSMC hates him so much. The lawsuit has been hit until 2015. Zhongtai Power has finally won the case. In the judicial and scientific circles in Taiwan, the first case was reached. After the end of the competition, it is still not possible to work for a competitor company.

But in the future, the grace and resentment between Liang Mengsong and TSMC will probably only be deeper, because Liang has been leaving Samsung at the end of 2016. It is said that he will go to SMIC as the chief of technology next month and shoulder the core. The advanced process technology that has been internationally closed.

With the current scale of SMIC, TSMC won't look at it, because TSMC really cares about competitors only Intel and Samsung, but the symbol behind SMIC is the index of the mainland semiconductor foundry industry. The object of full support, now the biggest traitor in TSMC’s eyes to go to the mainland, the mutual grievances will only be deeper.
