Crystal-originated pits
WebStone Mountain is an exposed granitic pluton, located in Northeast Georgia. Uniformitarian estimates suggest that the granite was intruded into overlying metamorphic rocks during … WebOne of the reasons for using annealed wafers is to allow a reduction in the crystal originated pits (COP), also sometimes known as crystal originated particles, near the top surface region of the wafer. The width of the denuded zone (DZ) free of bulk micro defects (BMD) is also an important parameter. Referenced SEMI Standards (purchase separately)
