WebJan 12, 2024 · Octahedral vacancy aggregates, the so-called crystal originated pits, are found in these wafers with sizes of 150 nm and densities of 106cm23. To meet the design rule requirements of 0.13 mm and below, a reduction of defect size and density is required. 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)
