Abstract

PURPOSE:To prevent malfunction due to a noise entering the signal lines of a control circuit board. CONSTITUTION:A control circuit board placed with a heat-sink board in a packaging case is formed by vertically stacking board main bodies 19 and 20. On both upper and rear sides of each board main body, wiring layers 21 to 24 defined in a P-side region and an N-side region are provided. A P-side circuit and an N-side circuit are formed in each region of the wiring layers 21 to 23, and the wiring layer 24 facing the heat-sink board is formed into an electromagnetically shielded layer. This prevents the P-side circuit or the N-side circuit from catching the noise produced in the other circuit or the noise from the heat-sink board. Accordingly, malfunction of the semiconductor device due to a noise can be prohibited to enhance the reliability.
