Patent ID: 8450847

Claim:
An optoelectronic device comprising: a carrier with at least one optoelectronic semiconductor chip on a main side of the carrier; a first metal layer on the main side of the carrier; at least one optical component with a second metal layer, wherein the second metal layer faces the main side of the carrier; and a friction welding seam situated between the first and the second metal layer and by which the optical component is mechanically connected to the carrier; wherein the friction welding seam is situated either 1) directly at the first metal layer and at the second metal layer, or 2) directly at the first metal layer and an optional connecting bump situated between the first and the second metal layer, or 3) directly at the second metal layer and said optional connecting bump, and wherein 1) the first and the second metal layer and the optional connecting bump are made of gold or a gold alloy, 2) a mechanically fixed and permanent connection between the carrier and the optical component is effected by the friction welding seam, 3) the first metal layer is electrically insulated from the optoelectronic semiconductor chip, 4) the first metal layer is applied on the carrier in at least four regions configured in a point fashion, and 5) the carrier and the optical component enclose a volume in which the at least one optoelectronic semiconductor chip is situated and said volume is not closed off in a gas-tight manner.
