Rebirth: Dominate The World, Starting From The School Network

People like Jia Qingyang and Ma were almost reduced to begging in America.

Lu Yi has no idea and will not care.

now.

He came to Pangu Semiconductor.

Mobile Processor Division.

"The 45nm process introduces a high-k insulating layer/metal gate configuration, which is definitely a milestone achievement.

"I have to say that the technology developed by Blue Star Electronics is really awesome."

"Both technologies are actually designed to solve the same problem: how to ensure that the gate works effectively in a very small size."

In the laboratory of the business unit, technical staff are having intense discussions.

This joint venture, established in January 2006, has now gone through three years.

Except for the initial news about the cooperation between Blue Star Electronics and Flower Factory, Pangu Semiconductor has been very low-key and has almost no presence in the industry.

But the lack of presence does not mean that Pangu Semiconductor has not achieved any results in the past three years.

on the contrary.

In the past three years, Pangu Semiconductor’s achievements have been very impressive.

Today's meeting is a technical seminar.

In addition to Lu Yi, Pangu Semiconductor CEO Yu Chengdong, as well as several scientists, researchers, and even several mathematicians will gather in this conference room.

The focus of the discussion at this meeting was the 22nm process technology node.

The process node of semiconductor manufacturing involves many aspects of issues.

For example, manufacturing processes and equipment, transistor architecture, materials, etc.

The so-called technology node.

Simply put, in the early days, it could be thought of as the size of the transistor.

This size is important.

Because the function of a transistor can be simply described as sending electrons from one end (S) through a channel to the other end (D). After this process is completed, the transmission of information is completed.

Because the speed of electrons is limited.

In modern transistors, they generally run at saturation speed, so the time required is basically determined by the length of the channel.

The shorter it is, the faster it is.

In the micron era, the smaller the number of this technology node, the smaller the size of the transistor and the smaller the channel length.

But after reaching the 22nm node, the actual size of the transistor, or the actual length of the channel, is longer than this number.

for example.

The channel length of a 14nm transistor is actually about 20nm.

Reducing the size of transistors can bring many benefits.

for example.

It can increase the clock frequency and thereby increase the processing speed.

Can improve performance and reduce costs.

But accordingly.

It is becoming increasingly difficult to break through relevant technical bottlenecks.

At the 65nm technology node, Ge-strained channels were introduced.

45nm introduces a high-k insulating layer/metal gate configuration.

As for the current most advanced 32nm technology node, it introduces the second-generation high-k insulating layer/metal gate process based on 45nm technology.

The most advanced technology node Pangu Semiconductor currently has is 28nm.

But at the 22nm node, there are internal differences.

Some people said that they can continue to move forward along the old path of 45nm.

Some people also say that the old road of 45nm has reached its limit when it reaches the 28nm node.

If you want to push the process technology node to 22nm, you need to introduce new technologies.

To this.

The two sides were divided into two groups and argued endlessly.

The routing (agbd) line issue is very important to Pangu Semiconductor.

Because technological breakthroughs cannot be achieved overnight.

Pangu Semiconductor is currently ahead of Intel in terms of technology nodes.

But after all, the background is too shallow.

Once the route is chosen incorrectly, time will be wasted.

This is not only a waste of a lot of money, but also more likely to be overtaken by Intel again.

so.

Pangu Semiconductor is very cautious about how to proceed with the next 22nm technology.

Pangu Semiconductor has been able to go from an unknown newcomer to what it is today.

This is not only the result of the joint efforts of all employees, but also the correct choice made in the previous route choices.

A senior research expert looked around at everyone and said: "It is safer for me to advance along the 28nm main line."

"We can continue to look for new metals to make gates, because there is an effect in metals called mirror charges, which can neutralize the impact of ohms in the insulating layer of high-K materials on the channel and Fermi level."

"In my opinion, the current curse that restricts the advanced development of semiconductor technology is that the short channel effect damages transistor performance."

"Short channel effect. In layman's terms, a transistor is a three-port switch. Its working principle is to send electrons from one end (source end) to the other end (drain end). This is done through the channel. In addition, There is a port (gate terminal) that determines whether the channel is open or closed."

"These operations are accomplished by applying specific voltages to the ports."

One thing that the performance of a transistor depends on is that it must be opened and closed tightly. "

"If it gets shorter and shorter, it will be OK to open it, but it won't close tightly."

"The reason is that the size is too small and there is a lot of mutual interference in the electric field inside."

"It used to be negligible, but now it will cause the electric field at the gate end to not be able to play its full role, so it is not tight."

"The consequence of not closing it tightly is current leakage."

"At this time, the transistor is resting, not doing anything, but consuming power in vain."

"Currently, the energy consumption caused by this part of the leakage current in integrated circuits has accounted for nearly 50% of the total energy consumption, so it is also the most important problem in current transistor design and circuit design."

"So, to put it bluntly, there is only one problem I have to solve, and that is the leakage problem. This door must be closed tightly!"

After the technical expert finished speaking, everyone nodded.

obviously.

This technical expert is right to the point. .
