Abstract The invention is a semiconductor device assembly and method of making the same. A mounting plate has positioning means for positioning the plate relative to a header, a first mounting surface of the plate is attached to the header and a semiconductor device is attached to a second mounting surface of the mounting plate. The assembly is made by forming the mounting plate, positioning the mounting plate relative to the header by the positioning means, attaching the first mounting surface to the header and the semiconductor device to the second mounting surface. Another method of making the assembly is by defining and etching a mounting plate and attaching the first mounting surface to the header and the semiconductor device to the second mounting surface. This assembly and process provides an efficient means for mounting semiconductor devices and in particular electro-optic devices such as lasers.
A semiconductor device assembly comprising: a header; a mounting plate composed of an electrically conductive material about 250 micrometers or less in thickness having opposed first and second major mounting surfaces and a leading edge surface extending therebetween with a first mounting surface attached to said header; a means for positioning said mounting plate relative to said header attached to said mounting plate; and a semiconductor device having an end face attached to said second mounting surface wherein said end face is substantially coplanar with said leading edge surface.
