The growth rate of China’s semiconductor wafer market scale is faster than that of the world
What is the prospect of the silicon wafer market?
Let’s first look at the structure of the semiconductor silicon wafer industry chain. The upstream is polysilicon, and the downstream is the manufacturing of integrated circuits and discrete devices.
From the upstream point of view, the main cost of producing polysilicon raw materials is electricity.
The main manufacturers of Chinese semiconductor silicon materials are Yellow River Hydropower, and the international companies are mainly German Wacker.
The downstream of semiconductor silicon wafers are foundries or IDM manufacturers. The quality of silicon wafers directly determines the yield and quality of chips.
Therefore, silicon wafer manufacturers need to meet the long quality verification period of the fab before forming a stable cooperative relationship. , silicon wafers are processed into semiconductor devices and then supplied to end-use applications.
Looking at the relevant market scale data, the strong downstream market demand drives the silicon wafer market.
90% of chips require silicon wafers as the basis, so the market size of semiconductor silicon wafers is consistent with the trend of changes in the size of the semiconductor market.
According to WSTS statistics and forecasts, global semiconductor sales will increase from $299.5 billion in 2011 to $551 billion in 2021, with a CAGR of 6.3%.
The declines in 2019 and 2020 were due to trade factors and the impact of the epidemic, respectively.
The popularity of 5G and the recovery of the automobile industry’s prosperity will lead to a new high in the scale of semiconductors in 2021, corresponding to an increase in the global silicon wafer shipment area from 9 billion square inches in 2011 to 12.5 billion square inches in 2020, with a CAGR of 3.7%.
In terms of price, after 2017, with the gradual recovery of demand, the price bottomed out, increasing from US$0.67/square inch in 2016 to US$0.91/square inch in 2020. Combined with the production needs of semiconductor production lines In about two years, silicon wafer prices are expected to remain.
The growth rate of China’s silicon wafer market is higher than that of the world.
With the growth of China’s silicon wafer market scale, China’s semiconductor market share in the world has gradually increased, from 27.3% in 2014 to 34% in 2020.
It is currently the world’s largest semiconductor market, and the gradual increase in the proportion has made the growth rate of the silicon wafer market in mainland China higher than that of the world.
The global silicon wafer market has a CAGR of 1.2% in the past ten years, and the Chinese mainland silicon wafer market has a CAGR of 10.4% in the past ten years.
With the expansion of China’s silicon wafer market, China’s silicon wafer cutting technology has gradually improved, walking in the forefront of the world.
At present, the new generation technology uses diamond wire loop to cut silicon wafers, which has the advantages of high cutting efficiency, low cost and less material loss.
