WebDec 7, 2004 · Crystal-related defects in the wafers have been correlated with decreased GOI (gate oxide integrity) performance. OPTIATM wafers have zero crystal-originated pits (COPs) and epi-like GOI, therefore, they provide an ideal solution for next generation IC devices. OPTIATM wafers are free of agglomerated defects WebUsing these results, a mechanism for the elimination of crystal-originated pits by thermal annealing is proposed. It is shown that the microscopic model is consistent with and allows to fine-tune existing macroscopic models that are used to calculate the intrinsic point defects behavior during crystal growth from a melt. dayday bigghead twitter
