The cornerstone of chip manufacturing - semiconductor wafer industry overview
Semiconductor silicon is the semiconductor material with the highest cost ratio and the most critical semiconductor material in the industrial chain. From the perspective of cost ratio, silicon chips accounted for 37% of the market in semiconductor materials, making it the largest semiconductor material. From the perspective of the industrial chain position, silicon wafers, as the starting point of the semiconductor industry chain, directly affect the manufacturing quality of chips. This paper mainly introduces the core semiconductor material silicon wafer and its industry situation in detail.
