Abstract:
A semiconductor-chip (11) is bonded to a chip-carrier substrate (12) by way of a gold-to-gold bonding interface. A vacuum chuck (63) is provided to physically hold the semiconductor-chip (11) in physical contact with the chip-carrier substrate (12) as static force (61), ultrasonic power, and an elevated temperature are applied to two mating gold surfaces that are formed by two continuous and physically mating gold layers. The bonded assembly is encased in potting ceramic, or the bonded assembly is encased in a housing that includes a transparent cover that enables use as an optoelectronic semiconductor device.

Abstract:
The invention relates to a contact bump connection (24) and to a method for producing a contact bump connection between an electronic component provided with at least one terminal face (11) and a contact substrate (26) contacted with the component and having at least one second terminal face (25), wherein the first terminal face is provided with a contact bump (10) which has a raised edge (15) and has at least one displacement pin (16) in a displacement compartment (18) which is surrounded by the raised edge and is open towards a head end of the contact bump, and in a contact region (31) with the first terminal face the second terminal face has a contact bead (30) which is formed by displacement of a contact material (29) of the second terminal face into the displacement compartment and surrounds the displacement pin, wherein said contact bead has a bead crown (33) which is directed to a base (17) of the displacement compartment and is raised relative to a level contact surface (32) of the second terminal face surrounding the contact region.
