•SOI LDMOS with buried multi-finger gates (BFG) is proposed and fabricated.•The BFG smoothen the electric field distribution along the drift region in the off-state.•The BFG enhance the carrier accumulation at the surface of drift region in the on-state.•BFG LDMOS exhibits improved BV, Ron and gm performance.
SOI LDMOS with buried multi-finger gates (BFG) is proposed and fabricated. The BFG acts as field plate, modulating the lateral electric field distribution in the drift region (off-state) and enhances the carrier accumulation at the surface of the drift region (on-state). The proposed BFG SOI LDMOS shows a 13.6% increase of breakdown voltage, 24.4% reduction of on-resistance and 14.4% increase of the transconductance compared with the reference SOI LDMOS without BFG.
