Claim:
1. A semiconductor device, comprising: an insulating substrate; a conductive pattern disposed on the insulating substrate; a conductive block disposed on the conductive pattern; a semiconductor chip disposed on the conductive block; a printed circuit board comprising a conductive post coupled to the semiconductor chip; and a resin disposed on the semiconductor chip and printed circuit board, wherein the conductive pattern comprises holes, and the number of holes per unit area of the conductive pattern increases in the direction away from the conductive block such that a first portion of the conductive pattern includes a first number of holes per unit area, a second portion of the conductive pattern includes a second number of holes per unit area, the second number of holes being greater than the first number of holes, and the first portion of the conductive pattern is disposed between the conductive block and the second portion of the conductive pattern.
