Silicon wafer, also called a slice wafer or silicon substrate, is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the fabrication of integrated circuits .Mostly,Prime wafer is the top grade silicon wafer compare to test wafer and dummy wafer.

What Are Silicon Wafers?
Silicon wafers are thin slices of semiconductor material, specifically crystalline silicon, that is used in electronics for the fabrication of integrated circuits. They are ultra-flat disks that are polished to a mirror-like surface and are virtually free of micro particles and other impurities. What Are Silicon Wafers Used For? Silicon wafers are found in countless devices that we rely on every day. For example, automobiles, digital appliances, wearable devices, smartphones, tablets, home appliances, televisions, computers, game devices, virtual reality, digital cameras, servers, cloud data centers, air conditioners, and nearly all other electronic equipment depends on silicon wafers. How Are Silicon Wafers Made? The silicon wafer manufacturing process consists of slicing a monocrystalline silicon block into disks that are no more than 1 mm thick. These disks are then put through advanced forming processes (e.g. lapping and polishing) that results in ultra-flat, ultra-clean silicon wafers.
