Does Moore's Law fail?

This is a question that has been repeatedly mentioned in recent years. Since it was proposed in 1965, Moore's Law has been advancing along the growing direction of the semiconductor process, but by the time of the 10 nanometer, there are many voices in the industry that Moore's Law has approached the corresponding physical limits and will lose utility The

However, in the September 19, "Intel Precision Manufacturing Day", the semiconductor industry leader for the above questions given their own answers.

Intel: Moore's Law will not be out of date

At the meeting, Intel's executive vice president and president of manufacturing, operations and sales group, Stacy Smith, emphasized the significance of Moore's Law. He said that according to Moore's observation, the number of transistors on the chip will be doubled every 24 months; that is, the performance of the semiconductor industry products doubled every two years, each transistor costs also decreased with the value. But Intel believes that Moore's Law actually reflects such an economic principle:

By pushing forward the progress of semiconductor manufacturing capabilities at specific rhythms, we can reduce the cost of any business model that depends on computing.


Smith said that the industry is often 16 nm, 14 nm, 10 nm and other process node numbers to measure the semiconductor industry process development, these figures did have its real physical significance, but now it is not the case. In fact, Smith gives another measure of performance: transistor density.

Therefore, in order to enhance the transistor density, in promoting the process to promote the process at the same time, Intel in the 14-nanometer process using fin-type field effect transistor (FinFET) and ultra-miniature technology (Hyper Sacling), which miniature technology can make 14 nm and 10 Nano chip area reduced by more than 0.5 times.

For the market competitors with 14 nm, 10 nm and other process node figures to highlight the advantages of the phenomenon, Smith also said that disdain. He said that although the number has changed, but in the FinFET technology competitor product transistor density did not improve; in fact, Samsung, TSMC 10 nanometer process technology transistor density is only equivalent to Intel 14 nanometer process transistor density, And the former launch time than Intel late three years.


In addition to the 14-nanometer process, Intel's 10-nanometer technology will also be mass production, and also use the ultra-miniature technology. Smith also said that Intel actually requires its own forward-looking three-generation process, is currently exploring the 7-nanometer and 5-nanometer process.

Smith finally stressed that Moore's Law would not end in any foreseeable future.

10 nanometer wafer world starting, about mass production

In this year, Intel for the world's first display of 10-nanometer Cannon Lake wafer. Mark Bohr, Intel Senior Fellow and Director of Process Architecture and Integration, Technology and Manufacturing Division, added to Moore's Law and 10-nm wafers.


Bohr first proposed a more quantified formula for calculating the transistor density:


This formula uses two logical concepts, one is a NAND cell, and one is a scan trigger logic unit. Divide the number of NAND2 transistors by the NAND2 cell area, or NAND density; divide the number of scan flip-flop transistors by the area of ​​the scan flip-flop to obtain the density; the former is multiplied by the 0.6 factor and the latter is multiplied by 0.4 The number of transistors per square millimeter, that is, the transistor density.

Bohr said that if calculated in this way, 10 nm in the transistor density is very obvious, for their own 14-nanometer technology 2.7 times, about the industry's other "10 nanometer" process 2 times. And this upgrade, thanks to Intel's ultra-miniature technology. In fact, the minimum gate spacing of the Intel 10 nanometer process is reduced from 70 nanometers to 54 nanometers and the minimum metal spacing is reduced from 52 nanometers to 36 nanometers. The reduced size allows the logic transistor to reach 100.8 million transistors per square millimeter.

Compared to the previous 14-nanometer process, Intel's 10-nanometer process boosts performance by up to 25 percent and reduces power consumption by 45 percent. The enhanced 10nm process will increase performance by 15 percent or 30 percent lower.


Bohr also said that Moore's Law's goal is to provide the transistor's density and reduce the cost through the intergenerational improvement of each generation, thereby reducing the average cost per transistor. The emergence of Intel 10-nanometer chip technology, but also just shows Moore's Law is not outdated, has been moving forward.

In fact, Intel also foundry business

In addition to cutting-edge chip technology to continue to explore, Intel is also a few years ago launched its own foundry business, has also entered the Chinese market; and in the "Intel Precision Manufacturing Day", responsible for the crystal Zane Ball, vice president of Intel's technology and manufacturing business at the foundry business, also introduced the foundry business.

Ball said that Intel's foundry advantage lies in technology. This is the first in the FinFET technology, Intel has produced 7 million chips using this technology; followed by 22 nm, 14 nm, 10 nm and 22FFL process technology.

Ball has focused on Intel's 22FFL (22nm FinFET low power) technology. According to Lei Feng network to understand, 22FFL is in March 2017 the United States and the United States for the first time announced the activities of a mobile application for ultra-low power FinFET technology, its technical basis is Intel's 22 nm / 14 Nano manufacturing experience.

Compared with the previous 22GP (general), 22FFL technology leakage can be reduced by up to 100 times, can provide mainstream technology in the leakage of the lowest transistor. It also achieves the same drive current as the Intel 14-nanocrystals to achieve a smaller area than the industry's 28nm / 22nm planar technology.

22FFL is another feature of the technology that is highly integrated; it contains a complete RF (RF) kit. With a broad pattern of design and simplicity, 22FFL is a cost-effective, easy-to-use design platform for a wide range of products, and is cost-competitive compared to the industry's 28-nanometer planar The


Relatively speaking, 22FFL new technology for low-power Internet of things and mobile products, it will performance, power consumption, density and easy to design features combined. Intel vice president Stacy Smith also said for 22FFL:

We think this is the industry's easiest to use FinFET process, serving the public's FinFET.


Based on the above technological advantages, Intel's foundry business is divided into two markets: one is the network infrastructure, such as network processors, FPGA; the other is mobile and networking equipment, especially the entry-level smart phone processor And networking equipment.

As a case of foundry business, Intel and ARM have collaborated to place the ARM Cortex A75 into the Intel standard foundry process. The entire process provided by the ARM IP, with 14 weeks to complete the first tape. This process uses Intel's 10-nanometer wafer foundry technology, the detection frequency can be at least more than 3.3 GHz; and from the display of data, it is very stable.

At the scene, Intel also collaborated with ARM to showcase the world's first ARM Cortex-A75 CPU core test chip with Intel 10nm process.

Tiger does not speak, you when I was sick cat ah

In the past Intel's impression is the main technology, very low-key; but this time Intel specifically set up a so-called "fine manufacturing day" to promote their own new technology, and positive Samsung, TSMC and other competitors. In this regard, Intel China president Yang Xu's response is "tiger does not speak, you when I was sick cat ah & rdquo ;.

However, in fact, this "fine tip manufacturing day" promotional focus is actually Intel's foundry business, especially for the Chinese market. However, Lei Feng network that Intel is so high-profile, in fact, still see the vigorous development of China's semiconductor industry. In the case of 58.5% of global semiconductor consumption in China, Intel naturally also hopes to get a share from the foundry business. But from the moment, the foundry business is only a small part of Intel's overall business.

As for the question of whether or not Moore's Law has failed, Intel has also taken a high profile gesture to name it and has tried to illustrate its long-term effectiveness through 10-nanometer process technology and other cutting-edge technologies.


In the Lei Feng network view, at least in the current said "Moore's Law has been outdated" too early, we also look forward to the semiconductor industry in a variety of cutting-edge advances in new technologies continue to move forward.
