Title: Improved step-coverage of electrode on semiconductor surface - uses preferential etching of the edge of surface layer to produce bevel
Inventor: HIRONAKA MISAO
IPC: H01L29/04
Filed: 1991-11-11
Abstract: In the stepcoverage of an electrode on the (100) major surface (31) of a semiconductor wafer, pref. III-V cpds., a layer (32) is epitaxially deposited. The layer is etched to produce an edge over which an electrode layer (33) is deposited. The edge of the upper semiconductor layer (35) is oriented along a (0,-1,1) direction and the surface of the slope is a (111) plane. The slope is formed by using a mask with a pattern edge oriented along a (0,-1,1) direction, etching the (100) surface of the epitaxial layer and depositing the electrode layer (33). The etchant used is pref. a set etch composed of H2SO4, H2O2 and H2O. The mask pattern pref. contains at least one edge in another (0,-1.1) direction which is connected with the sloping edge. USE/ADVANTAGE - The edge orientation causes the etch to proceed along (111) planes which have an angle of 54.7 degrees with the horizontal. As a result the slope is easy to sputter coat with the electrode layer, producing a thickness on the slope (ts) which is in the order of 58% of the electrode layer thickness on the plane (to). The method is used in the mfr. of e.g, lasers.
