On June 9, the 2021 World semiconductor Conference and Nanjing International Semiconductor Expo were held in Nanjing. Wu Hanming, academician of the Chinese Academy of Engineering and dean of the School of Micro-Nano Electronics of Zhejiang University, delivered a speech on “Chip Challenges and Opportunities in the Post-Moore Era”.

He pointed out that Chinese experts have made predictions on the effectiveness of Moore’s Law (technology) – Moore’s Law will fail in 2014-2017, but silicon-based life is still very long.

Judging from the release of the global integrated circuit industry chain, in many aspects, the United States has a dominant position, but they still have shortcomings in manufacturing and packaging and testing. The United States needs to make up for the shortcomings, and the cost of building a completely independent and controllable industrial chain will reach 900 billion to 1.2 trillion US dollars, which will lead to a price increase of 65%.

As far as the chip manufacturing process is concerned, there are three major challenges in the chip manufacturing process, namely the basic challenge: precision graphics; the core challenge: new materials; the ultimate challenge: improving yield.

Wu Hanming pointed out that in the post-Moore era, high-performance computing, mobile computing and autonomous perception are the three driving forces for industrial development. From this, eight major contents and four goals of PPAC are derived.

The post-Moore era presents an opportunity for chasers. The four categories of directions in the catch-up process are the “silicon-von” paradigm, the silicon-like model, the brain-like model, and the emerging paradigm.

Wu Hanming pointed out that in the integrated circuit industry, research is the means, industry is the goal, and production capacity is king.

In this speech, Wu Hanming cited an article in “China Science News” and pointed out that in order to develop the integrated circuit industry in my country, it is necessary to establish an industrial technology-oriented scientific and technological culture:

1. Industrial technology is not the application development after the transformation of scientific research institutions, but the original driving force to guide scientific research

2. Goal-oriented research, not looking at new achievements, but looking at the needs of industrial technology

3. Laboratory technology is a single-point breakthrough, and one beauty hides a hundred ugliness, while industrial technology cannot have obvious shortcomings.

Lab techniques might solve 90% of the requirements, but the remaining 10% might take 10 times more effort.

4. Adhere to the global technology development route, make major adjustments in concept, and advocate a community of shared future for enterprises to innovate
