Silicon Wafer

About Silicon Wafer

Silicon wafers are high purity Si wafers which are thinly sliced from so-called ingot of cylinder single crystal.

Generally, large diameter wafers are used in big MPU which has a chip size, DRAM which is required to decrease cost by mass production, and flash memory.
They are mostly used for production of integrated circuit (IC/LSI).

Mirror processed polish wafers are being used as silicon wafers for semicondutor device, however to look through the content in detail, there are several levels divided by density of COP (Crystal Originated Particle), besides, there are variation such as epi wafer and FZ wafer etc.
These are being used in manufacture of device by considering cost and characteristics.

Most of silicon wafers are made by CZ method.
