Abstract :
Molybdenum silicide (MoSi2) gate technology has been extensively investigated in conjunction with MOS device performance and reliability. Features of the MoSi2) gate technology are to realize a low resistivity of 1 X 10-4 Omega · cm for both gate and interconnection, and to give rise to higher reliability under both positive and negative bias stress of 2 MV/cm at 250°C. Problems on the ohmic contact between MoSi2 and single-crystal substrates are not completely solved yet, particularly when the device is processed at high temperature after MoSi2 deposition.
