Abstract
Abstract The invention relates to the combination of a support and a semiconductor body and to a method of manufacturing same, in which a deformable metal layer is disposed between the semiconductor body and the support. The semiconductor body is connected to the support by pressing the semiconductor body and the support against each other under pressure after heating the metal layer. The semiconductor body is then provided at its surface facing the support with at least one projecting part, which is embedded in the metal layer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
A method of connecting a semiconductor body to a support, said method comprising forming at least one projecting part, projecting from the surface of the semiconductor body to face the support, providing a deformable metal layer between the surface of the semiconductor body provided with the projection and the support and then pressing the support and the semiconductor body under pressure at an elevated temperature in a manner such that the projecting part is pressed into the metal layer.
Claim 2
Independent Claim
79 words
A method of connecting a semiconductor body to a support, said method comprising forming at least one projecting part, projecting from the surface of the semiconductor body to face the support, providing a deformable metal layer between the surface of the semiconductor body provided with the projection and the support and then pressing the support and the semiconductor body under pressure at an elevated temperature in a manner such that the projecting part is pressed into the metal layer.
Claim 3
Independent Claim
81 words
A method of connecting a semiconductor body to a support, said method comprising forming, by etching, at least one projecting part, projecting from the surface of the semiconductor body to face the support, providing a deformable metal layer between the surface of the semiconductor body provided with the projection and the support and then pressing the support and the semiconductor body under pressure at an elevated temperature in a manner such that the projecting part is pressed into the metal layer.
Claim 4
Independent Claim
81 words
A method of connecting a semiconductor body to a support, said method comprising forming, by etching, at least one projecting part, projecting from the surface of the semiconductor body to face the support, providing a deformable metal layer between the surface of the semiconductor body provided with the projection and the support and then pressing the support and the semiconductor body under pressure at an elevated temperature in a manner such that the projecting part is pressed into the metal layer.
