Abstract
Abstract A carrier for semiconductor components which improves the electrical properties and the lifetime of the semiconductor components. The carrier is characterized by a carrier portion comprising electricity and heat conducting material and by a thin adhesive electrical insulation layer, at least on that surface of the carrier member that faces the semiconductor component.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
25 words
The luminescence diode of claim 1, wherein the contact piece and chromium/nickel layer are connected to the diode by means of a thin tin layer.
Claim 2
Independent Claim
154 words
The method of producing a luminescence diode, which comprises soldering a contact piece of nickel onto a planar carrier member of tantalum, thermally oxidizing a layer of tantalum oxide on the contact piece, reducing the nickel oxide which results on the surface of the contact piece in a hydrogen atmosphere, vapor depositing in a vacuum a chromium/nickel layer which surrounds said contact piece upon the tantalum oxide layer, gold plating of the nickel contact piece and the surface of the chromium/nickel layer, so that both the gold-plated surface of the chromium/nickel layer and the top surface of the contact piece lie in one plane, whereby the metal contact piece Leading to one diode region and the metal layer which surrounds with clearance said metal contact piece and which is to contact the other diode region, are firmly soldered with the two tin-plated contact surfaces of the diode that are situated in the same plane.
