Patent number: 12230707Abstract: A semiconductor structure that includes at least one lateral diffusion field effect transistor is described. The structure includes a source contact and a gate shield that enables the line width of an ohmic region that electrically connects the source/body region to the gate shield to be smaller than the minimum contact feature size. The gate shield defines a bottom recess for forming a narrower bottom portion of the source contact, and a section that flares outward with distance from the ohmic region to extend above and laterally beyond the ohmic region. By providing a wider area for the source contact, the flared portion of the gate shield allows the portion of the gate shield that contacts the ohmic region to be narrower than the minimum contact feature size. As a result, the cell pitch of the lateral diffusion field effect transistor can be reduced.Type: GrantFiled: June 21, 2023Date of Patent: February 18, 2025Assignee: Silanna Asia Pte LtdInventors: Touhidur Rahman, Shanghui Larry Tu
