After completing the design, China first sent to a factory in Italy, that is, to engrad complex circuits on the original silicon wafer. Then, the silicon chips were sent to Taiwan, China for packaging and testing. Then they were shipped to the Chinese mainland to assemble camera parts, and then sent to the modern automobile parts suppliers in Korea, and finally to the modern automobile production factory. < / P > < p > the shortage of this kind of image sensor has led to the shutdown of Hyundai's Korean factory, making it the latest auto manufacturer to suffer from global supply difficulties. The same problem has paralyzed the production of most automobile manufacturers, such as general motors, Ford and Volkswagen. < / P > < p > the tortuous journey of the image sensor supply chain shows how complex it is for the chip industry to solve the current supply shortage problem, and how difficult the task of revitalizing the chip manufacturing industry in the United States is. < / P > < p > on Monday, local time, President Biden convened semiconductor industry executives in Washington to discuss solutions to the current chip crisis, the latest move by the US government to revitalize the US domestic chip industry. In addition, as part of the US government's US $2 trillion infrastructure plan, Biden also proposed to invest US $50 billion in US chip manufacturing and R & D, saying it would help the us win global competition. < / P > < p > most of the $50 billion in chip manufacturing and R & D funds may be used to subsidize Intel, Samsung and TSMC's new advanced chip factories in the United States. But industry executives say it is crucial to address broader supply chain issues. Therefore, Biden government is faced with the complicated choice of the direction of government funding subsidies. < / P > < p > "it's impossible to try to rebuild the entire supply chain from upstream to downstream," David SOMO, senior vice president of on semiconductor, told the media. "Because that would be an outrageous price to pay." < / P > < p > at present, the United States only accounts for about 12% of the global semiconductor chip manufacturing capacity, lower than 37% in 1990. According to industry data, more than 80% of the global chip production capacity is distributed in Asia. < / P > < p > it takes more than 1000 steps to produce a computer chip, through 70 independent border ports and many professional companies. Most of these companies are in Asia, and many are not well-known. < / P > < p > the whole process of chip production starts from the original silicon wafer, passes through the chip factory called "wafer factory", and etches the circuit into the silicon wafer through complex chemical processes. After that, we enter the chip packaging stage. < / P > < p > the packaging step best illustrates the challenges of the supply chain. Silicon wafers produced from wafer factories contain hundreds or even thousands of nail sized chips, which must be cut into separate chips and put into a packaging unit. < / P > < p > the so-called packaging is to put a single chip into a "lead frame", weld it to the circuit board, and package it into a resin protective shell.

, because this step is completed in labor-intensive jobs, the chip company has outsourced this business to mainland China, Chinese mainland Taiwan, Malaysia and Philippines decades ago. < / P > < p > "if the Biden administration's efforts to revitalize the chip industry can succeed, they must help rebuild the chip packaging industry in the United States." "Otherwise, it's a waste of time," said Dick Otte, chief executive of Promex, a California chip packaging company. It's like building a car without a body. " < / P > < p > however, the relatively new chip packaging process and the reduced dependence on labor-intensive jobs have led some US chip manufacturers to believe that they can pull the chip manufacturing industry back from abroad. < / P > < p > according to Tony Levi, a professor of electronic and computer engineering at the University of Southern California, rebuilding the US chip packaging industry will not only protect chip companies and their customers from geopolitical risks, but also help them produce the chips they need faster. < / P > < p > Levi said that Intel, TSMC, Samsung and global foundries all have factories or are planning to set up factories in Arizona, Texas and New York, and these three states will be suitable for developing into supply chain clusters. < / P > < p > Levi said, "what America is very good at is the close cooperation between system design, product design and manufacturing itself." < / P > < p > Tyson Tuttle, chief executive of silicon labs, a chip design company, points out that there is a serious shortage of mature chips. Therefore, industry insiders believe that the United States not only needs to invest in the construction of advanced technology wafer plants, but also needs to invest in old and mature technologies. < / P > < p > Tuttle said, "the investment in the semiconductor industry is uneven, and the investment in the most advanced technology is excessive." < / P > < p > however, it remains to be seen how the Biden administration will balance the required investment in many sub sectors of the chip industry.

The chairman of TSMC was also invited to attend. < / P > < p > Biden still used China to play up the sense of urgency at the meeting, claiming that "China plans to priority and dominate the semiconductor supply chain", and the United States can't sit by and watch. 拜登也不忘“心心念?
