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 18):
A semiconductor device, comprising:\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; a plurality of semiconductor chips on the first surface side of the circuit substrate; a metal plate on the second surface side of the circuit substrate; and a solder layer between the metal plate and the second metal layer, wherein the second metal layer includes:\n a plurality of protruding regions which each extend from the insulating layer for a first thickness distance towards the metal plate, and \n a plurality of recessed regions adjacent to each first protruding region, each protruding region being between at least a pair of recessed regions from the plurality, each recessed region extending from the insulating layer for a second thickness distance that is less than the first thickness distance.
