Abstract :
The optimization of resurfed LDMOS transistors is considered in this paper. A new interdigitated LDMOS layout, characterized by a waved gate electrode, which theoretically predicts an improvement around 10% in the device specific ON-resistance, RONxS, iS presented. The experimental results from devices fabricated on epi-wafers with optimal properties, obtained from an analytical model for the device OFF-state, show the validity of the decrease of RONXS for this waved gate layout.
