ABSTRACT:
This invention relates to a substrate for semiconductor apparatus loading a semiconductor chip in integrated circuit apparatus and is characterized in that a sintered compact containing copper of 2 to 30 wt. % in tungsten and/or molybdenum is used as the substrate having the heat radiation capable of efficiently radiating heat developed from the loaded semiconductor chip and thermal expansion coefficient similar to those of semiconductor chip and other enclosure material except for the substrate.
