Method of simultaneously manufacturing multiple electrical connections between two electrical elements
First Claim
1. A method for simultaneously electrically connecting two semiconductor elements each having a plurality of mutually-opposing contact pad metallizations, which comprises:
- applying an electrically-conductive paste to each of said contact pad metallizations on at least one of said two elements;
thenpolymerizing said electrically-conductive paste;
thencompressing said polymerized electrically-conductive paste between the mutually-opposing contact pad metallizations of said two elements; and
heating at least one of said two elements being connected during compression.

Abstract
A method for the simultaneous manufacture of multiple electrical connections, in particular for the electrical connection of semiconductor elements. In the method a conductive paste is used. Because the conductive paste would otherwise provide a poor electrical connection with the contact pads which are manufactured of certain metals, the paste is first polymerized and thermo-compression of the paste is then carried out on the contact pad by the simultaneous application of pressure and a rise in temperature so that the paste forms a readily conductive and reliable connection.
