Abstract:
1. A method of producing a contact connection between a semiconductor chip and a substrate, said method comprising steps of providing a substrate having a first contact surface, providing a semiconductor chip having a second contact surface, applying a curable conductive adhesive to at least one of the first contact surface and the second contact surface, the conductive adhesive having a matrix component, a filler component consisting of conductive solid particles, a hardener component and at least one decomposable component which after curing at a temperature T 1 can be decomposed by applying energy selected from radiation energy and thermal energy at a higher temperature T 2 >T 1 so that the first contact surface and the second contact surface can be smoothly separated mechanically, joining the first contact surface and second contact surface together and curing the adhesive to strengthen the contact connection mechanically.
