Description
The OPTIA™ wafer is a high performance silicon substrate for the VLSI and ULSI IC device generations. These devices are built today with increasingly denser and more complex architectures. Consequently, increasingly tighter specifications are required for silicon substrates. Crystal-related defects in the wafers have been correlated with decreased GOI (gate oxide integrity) performance. OPTIA™ wafers have zero crystaloriginated pits (COPs) and epi-like GOI, therefore, they provide an ideal solution for next generation IC devices. OPTIA™ wafers are free of agglomerated defects across the wafer and throughout the whole wafer thickness. OPTIA™ wafers are enhanced using MEMC's patented Magic Denuded Zone® (MDZ®) thermal treatment. MDZ® produces a deep precipitate free zone and provides robust internal gettering protection early in the IC fabrication process.
