0.5μm Sea Of Gates An Customer Structured Arrays

Oki's second-generation 0.5m ASIC products are available in both Sea Of Gates (SOG) and Custome Structured Array (CSA) architectures. The MSM30R Series, MSM32R Series, and MSM92R Series all offer increased density over their first-generation counterparts, as well as 3-V I/O Buffers that are 5-V tolerant. Both the SOG-based MSM30R Series and the CSA-based MSM92R Series use a three-layer metal process on 0.5m drawn (0.4m L-effective) CMOS technology. The SOG-based MSM32R Series uses the sa SOG base-array architecture as the MSM30R Series, but offers two metal layers instead of three. The semiconductor process is adapted from Oki's production-proven 16-Mbit DRAM manufacturing process. By Oki Semiconductor
