  • Abstract
    A 1 µm n-well CMOS technology with high latchup immunity is designed, realized, and characterized. The main features of this technology are : 1 MeV ion-implanted retrograde n-well, buried contact, arsenic-phosphorous double diffused n+/n-junction, self-aligned TiSi2on gate and diffusions with nitride spacer, and thin p epi on p+substrate. This technology has been demonstrated via the successful fabrication of high-performance 64K CMOS SRAM chips. It is also observed that the silicide plays an important role in latchup prevention since it reduces the emitter efficiencies of parasitic bipolar devices.
