Abstract:
A gate trench and a protective trench are provided on a top surface of the silicon carbide semiconductor layer of a first conductivity type. A protective diffusion layer of a second conductivity type is provided at a position deeper than the gate electrode in the silicon carbide semiconductor layer. An inter-layer insulating film covers a surface of the gate electrode and includes a cell opening. A source electrode is electrically connected to the source region via the cell opening and electrically connected to the protective diffusion layer via the protective trench. A plated film is provided on the source electrode. A concave part is provided on a top surface of the source electrode above the protective trench. A depth in a vertical direction of the concave part is equal to or less than half of a width in a horizontal direction of the concave part.

Claim (Index 9):
The silicon carbide semiconductor device according to  claim 3 , wherein the gate electrode is not provided between the cell opening adjacent to the protective trench and the protective trench.
