SPLIT-GATE SILICON CARBIDE DEVICE WITH BURIED FIELD LIMITING RING AND PREPARATION METHOD THEREOF

Filed:2023-05-15Pub:2026-06-18
Applicant:Fudan University

The present invention discloses a split-gate silicon carbide device with a buried field limiting ring and a preparation method thereof. The device comprises, from bottom to top, a drain electrode, a drift region and a P-well region, and also comprises a trench, which runs through the P-well region; a buried P-type field limiting ring, which is formed on the periphery of the trench bottom; a P + region and an N + region, which are connected to each other and formed on the P-well region on both sides of the trench; a gate electrode, which is formed in the trench, including a transistor gate located on the outer side and a field limiting ring contact plug located in the middle region, the transistor gate being wrapped in an oxide layer, the top of the field limiting ring contact plug being connected to the source electrode, the bottom of the field limiting ring contact plug being connected to the buried P-type field limiting ring; and a source electrode, which covers the surface of the device, wherein the P-type field limiting ring is connected to the source electrode through the field limiting ring contact plug, achieving equipotential with the source electrode to reduce the electric field in the gate oxide layer on both sides of the trench, so that the device depletion region is limited outside the channel region on both sides of the trench in the reverse bias state.
