ELECTRONIC DEVICE AND METHOD OF MANUFACTURING A SUBSTRATE

摘要

Provided is an electronic device (1) with a semiconductor element (5) and a substrate (3) of a material chosen from the group of AlSi, AlSiC, AlSiGe and the like. These materials are provided by providing preferably crystalline particles of a semiconductor material in a thermally conducting matrix material, after which the material is adequately strengthened by a heat treatment. The semiconductor element (5) is a digital integrated circuit with a large number of first contact pad (32) by preference. In such applications, thermal mismatch can easily lead to breakdown of the packaged device. This is prevented through the use of the substrate (3) of the invention.
