Abstract:
A trench gate lead-out structure comprises a substrate ( 10 ), a trench formed in the surface of the substrate ( 10 ) and a first dielectric layer ( 22 ) on the substrate ( 10 ), and also comprises a polysilicon gate ( 31 ) at the inner surface of the trench. The trench is partially filled by the polysilicon gate ( 31 ), so that a recess exists in the trench above the polysilicon gate ( 31 ). A second dielectric layer ( 41 ) is filled in the recess. The trench gate lead-out structure also comprises a metal plug ( 50 ). The metal plug ( 50 ) downwards penetrates through the first dielectric layer ( 22 ) and then is inserted between the second dielectric layer ( 41 ) and the polysilicon gate ( 31 ), and accordingly is connected to the polysilicon gate ( 31 ).

Claim (Index 1):
A trench gate lead-out structure, comprising:\n a substrate; a trench located on a surface of the substrate; a first dielectric layer located on the substrate; a gate oxide layer located on an inner surface of the trench; a polysilicon gate located on the gate oxide layer, wherein the trench is partially filled with the polysilicon gate, such that a recess is formed on a surface of the polysilicon gate; a second dielectric layer filled in the recess; and a metal plug extending downwardly through the first dielectric layer and being inserted between the second dielectric layer and the polysilicon gate, such that the metal plug is connected to the polysilicon gate.
