Abstract:The anomalous threshold voltage behavior of sub-halfmicron LOCOS-isolated n-MOSFETs is explained by the segregation of boron and narrow-mask effect of local oxidation. A novel approach to simulating narrow-width effects is proposed. It combines 2-D process and device simulations and analytical calculations of the threshold voltage shift.
