Abstract
Abstract In the particular embodiments of the invention described in the specification, a semiconductor package is made from two modules, one containing a semiconductor element having a high allowable temperature and the other containing a circuit component having a lower allowable temperature. The modules are combined by corresponding embossed and recessed surfaces or by pin connection or by a connecting screw.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
170 words
A semiconductive package comprising a first case of a first resin having a relatively high heat resistance and including semiconductive elements tolerant of relatively high operating temperatures and free of components intolerant of an operating temperature in excess of a given temperature, and a second case of a second resin having a relatively lower heat resistance and including semiconductive elements intolerant of operating temperatures in excess of the given temperature, the first case including a first set of terminals for interconnecting its components with the components in the second case, the second case including a second set of terminals for interconnecting its components with the components in the first case, one of two sets of terminals projecting from its case, the other of the two sets being in recessed means in its case, the projecting terminals removably merging with the terminals in the recessed means, electrically interconnecting the two sets of terminals and merging the two cases together to form an intimate interface between the two cases at the merger.
