Halbleitergerät mit gleichmäßigen Strompfaden und kleinem Aufbau

摘要

An electrode wiring structure is disclosed which realizes a smaller semiconductor apparatus as a power semiconductor module with the current path set as shortest as possible. The semiconductor apparatus includes: a plurality of semiconductor devices mounted in one array or more on a substrate; a main current electrode mounted along the array(s) of the semiconductor devices, and commonly connected to each of the plurality of semiconductor devices through the substrate by being connected to the substrate through a plurality of wires; an insulated base mounted on the main current electrode, and covering the connection area of the wires connecting the main current electrode; and a drive electrode mounted on the base, and commonly connected to each of the semiconductor devices.
