Abstract:
A semiconductor device includes a circuit substrate having a first metal layer on a first side, a second metal later on a second side, and an insulating layer between the first and second metal layers. A semiconductor chip is on the first side of the circuit substrate. A metal plate is on the second side. A solder layer is between the metal plate and the second metal layer. The second metal layer includes a protruding region which extends to a first thickness towards the metal plate, a first recessed region, and a second recessed region, each adjacent to the protruding region. The first recessed region extends to a second thickness that is less than the first thickness, and the second recessed region extends to a third thickness that is less than the first thickness.

Claim (Index 16):
A semiconductor device, comprising:\n a frame body, a lid, and a metal plate enclosing:\n a circuit substrate having a first metal layer on a first surface side, a second metal later on a second surface side, and an insulating layer between the first and second metal layers; \n a semiconductor chip on the first surface side of the circuit substrate; and \n a solder layer between the metal plate and the second metal layer, wherein the second metal layer includes a first protruding region which extends from the insulating layer for a first thickness distance towards the metal plate, a first recessed region adjacent to the first protruding region, and a second recessed region adjacent to the first protruding region, the first protruding region is between the first and second recessed regions, the first recessed region extends from the insulating layer for a second thickness distance that is less than the first thickness distance, and the second recessed region extends from the insulating layer for a third thickness distance that is less than the first thickness distance.
