Semi Grade 4-inch Polished Silicon Wafer 100mm Si Wafers
Silicon wafer is the basic material for making semiconductor chips, Silicon is the second most common element in the earth's crust, accounting for about 26%, second only to oxygen (49%). Silicon is widely present in high-concentration sand, gravel and rocks in the form of quartz (silica) in nature. Then through a series of complex processes such as purification and processing, it becomes the basic raw material-silicon wafer that meets the requirements of producing integrated circuits.
