OPTOELEKTRONISCHES HALBLEITERBAUELEMENT MIT STROMAUFWEITUNGSSCHICHT

摘要

#CMT# #/CMT# Semi-conductor unit has semi-conductor base (10) at least partly laid on a current expansion layer (3). Layer contains metal (1) which forms a transparent conductive metal oxide (2). The concentration of metal decreases moving from the side of the expansion layer facing the semi-conductor base to the side of the layer turned away from the semi-conductor base. Method to make semi-conductor part involves firstly putting on metal layer on the base, secondly putting on a metal oxide on the metal layer and lastly heat treating the layers to produce the current expansion layer. #CMT#USE : #/CMT# The part is an opto-electronic semi-conductor. #CMT#ADVANTAGE : #/CMT# The semi-conductor part produces both electrically and mechanically stable contact. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the opto-electronic part produced using inventive method. 1 : metal 2 : metal oxide 3 : current expansion layer 10 : semi-conductor base.
