Patent ID: 7679184

Claim:
A semiconductor device comprising: a substrate; a semiconductor chip which is mounted on the substrate with a front surface of the semiconductor chip facing downward; a sealing resin layer which seals the semiconductor chip; a cooling member which is bonded to an upper surface of the sealing resin layer; a cavity enclosed by at least a lower surface of the cooling member and a rear surface of the semiconductor chip which is exposed on the sealing resin layer; and a liquid cooling medium which is encapsulated in the cavity, wherein the rear surface of the semiconductor chip is positioned lower than an uppermost surface of the sealing resin layer and wherein at least a part of the upper surface of the sealing resin layer is inclined toward the rear surface of the semiconductor chip, and an upper surface of the liquid cooling medium is positioned lower than a level of the uppermost surface of the sealing resin layer when the semiconductor device is horizontally placed.
