MOSFETs are arguably the most common transistors and require little to no input current to control the load current.

There are many different types of MOSFETs, but they can basically be divided into two types: enhanced and depletion.

These two types can then be used as either N-channel or P-channel.

MOSFETs are planar transistors, while the FinFET architecture invented by Hu Zhengming is a 3D transistor, which can overcome the short-channel effect that the transistor itself may encounter.

Put simply, FinFETs can achieve higher performance metrics at a lower cost. The design of finFETs is mainly to break through the 25nm process and solve the tunneling effect associated with MOSFETs due to process reduction.

Of course, from the FinFET architecture proposed by Hu Zhengming in 2000 to 2001, when Hu Zhengming joined TSMC as the chief expert, TSMC only came up with the first real FinFET transistor in December 2002.

It wasn't until 2012 that transistors with a commercially available 22nm FinFET architecture were available.

It's a very long process.

Zhou Xin wants to talk about a certain optimization of MOSFET architecture.

There's a bit of FinFET architecture thinking in there.

But if you think along this path, you will take a detour.

“...... We can find that when there is no voltage at one end, the channel shows maximum conductance. When both voltages are positive or negative, the conductivity of the channel decreases.

We try to turn off the non-conducting region and let the MOSFET use the ohmbracket as the amplifier while the region is working.

In the saturation region the IMDS of the MOSFET is constant, although the VDS increases and occurs as soon as the VDS exceeds the value of the pinch voltage Vp.

In this case, the device will work like a closed switch through which saturated IDS values flow.

Therefore, whenever a MOSFET is required to perform switching operation, this operating area is selected......

This allows us to allow the MOSFETs to operate at higher efficiency at lower voltages. ”

After Zhou Xin's paper was finished, there was polite applause backstage.

Because Zhouxin's content is a pure model, that is, a more excellent MOSFET architecture is described from a theoretical level, but there is a lack of experimental data.

Just because a lot of things are perfectly designed doesn't mean that they are really so perfect when they are reproduced in the lab.

The real world is not as perfect as theoretical deductions.

However, purely in terms of content, Zhou's new MOSFET architecture gave the researchers present a lot to think about.

In the follow-up questions about the content of the paper itself, Zhou Xin also couldn't find any fault with it.

At the end of the question session, the applause from the audience was much more sincere.

The paper itself can prove part of it, and the question session can further verify Zhou Xin's own strength.

Everyone is a researcher, wealth and assets are just add-ons, and your own strength in scientific research will make the researchers present feel close.

This kid is the same as us.

"Very good, if you weren't my student, I'd think you're a veteran who has been here many times.

You are very mature, and basically everyone is familiar with you after coming a few more times, and you want to do something in the future, and it is very beneficial for you to know these people.

Maybe they won't come back to China with you, but you can set up an R&D center in Silicon Valley or Europa.

It couldn't be easier for you. Hu Zhengming said in Chinese while clapping while waiting for Zhou Xin to come down in the audience.

"In the future, I will take you to know some researchers who have more prospects in the field of integrated circuits.

Do you still want to go back to China to start a business in the field of integrated circuits? Hu Zhengming then asked.

People's perceptions are constantly changing.

Zhou Xin has achieved financial freedom in Ameriken, and Hu Zhengming was worried that the other party's mind had changed, so he asked more.

Zhou Xin nodded and said: "Yes, Huaguo is too backward in the field of integrated circuits.

I still want to go back and train a group of talents.

According to my observations, there are very few branches established by foreign giants in the semiconductor field in China.

Even if there is a branch, the established branch is to do some assembly, packaging and testing relatively low-end and non-technical work. ”

"Taking Intel as an example, Intel set up a R&D center in Yanjing last year, but the R&D center is mainly R&D at the software level, not at the hardware level."

"A large part of this is because China has not yet joined the WTO.

In China, OEM has the advantage of labor costs, but tariffs will offset this part of the advantage.

At the same time, Huaguo lacks engineers in the semiconductor field, and many things need to be cultivated from scratch.

I expect that after China's accession to the WTO, companies in the field of integrated circuits will enter China one after another to set up factories.

It's the same as these companies going to Neon, Goryeo, and Wanwan to set up foundries.

This is an opportunity for Huaguo to use these integrated circuit companies to set up factories to train Huaguo's engineers.

These engineers will contribute to the independent R&D and independent innovation of Huaguo's semiconductor industry.

We don't need to worry too much. A young man with a yellow appearance sitting behind Zhou Xin said.

Hu Zhengming looked back and saw that they were already chatting in Chinese in order to avoid suspicion, but there were too many acquaintances who could not stand up to ISSCC, and the number of Chinese who came to participate was also large.

"Lao Guan, you should say hello first if you interject!" Hu Zhengming said unhappily.

Zhou Xin looked back and recognized the other party, Guan Jianying, a bent person.

Basically, as long as it is a bend in the field of integrated circuits, Hu Zhengming knows it.

can be active until 2020, Hu Zhengming's acquaintance is equivalent to Zhou Xin's acquaintance, and various academic conferences are to take him everywhere to meet friends.

This is also why Zhou Xin returned to 1998 to study Hu Zhengming's graduate school, and his connections are here.

Zhou Xin heard Hu Zhengming privately ridicule the other party as a key eagle, because Hu Zhengming believes that the other party's sense of smell is extremely sensitive, and he can see opportunities that others can't see, and he can also see crises that others can't see.

Guan Jianying later turned around and started a business and founded a company called Worldchip Semiconductor, which at the beginning mainly designed special chips for Sony's game consoles.

From PS2 to PS5, a large number of chip designs and foundries come from Worldchip.

With this start, Shixin focuses on the design and foundry of various large chips such as CPU/GPU/NETWORKING/AI, and is the second integrated circuit design service company in the global market share in 2021.

Later, Shixin provided a large number of chips and even chip design services to a certain rumored military-related enterprise in Huaguo, Tianjin Feiteng.

Feiteng has been the most important partner of Shixin for a long time, and since 2018, Shixin has gradually reduced its dependence on Feiteng.

Sure enough, in 2021, Ameriken blacklisted Feiteng and banned semiconductor companies from selling chips to Feiteng. Even if Alchip intends to reduce its dependence on Feiteng, Feiteng still accounts for 39% of Worldchip's revenue at this point in time.

Because of the relationship between Guan Jianying and Hu Zhengming, Guan Jianying regarded Zhou Xin as a junior, and privately persuaded Zhou Xin not to go to Zhongxing several times.
