Abstract

A lateral double diffused metal oxide semiconductor field-effect transistor includes semiconductor substrates, body regions positioned in the semiconductor substrates, drift regions positioned in the semiconductor substrates, source regions and a body leading-out region which are positioned in the body regions and spaced from the drift regions, a field region and drain regions which are positioned in the drift regions, and gates positioned on the surfaces of the semiconductor substrates to partially cover the body regions, the drift regions and the field region, wherein the field region is of a finger-like structure and comprises a plurality of strip field regions which extend from the source regions to the drain regions and are isolated by the active regions; and the strip field regions provided with strip gate extending regions extending from the gates.
