Patent ID: 6919232

Claim:
A process for producing a plurality of semiconductor chips having resilient contact elements protruding on one semiconductor chip side within the context of wafer level packaging; characterized in that wherein the semiconductor chip side provided with the resilient contact elements is coated with a covering compound forming a protective layer from which the protruding resilient contact elements project (a) wherein said plurality of semiconductor chips are arranged in a mold as separated semiconductor chips or bound in a wafer, one half of such mold being directed to rear sides of said semiconductor chips and the other half of said mold directed to said resilient contact elements, wherein one mold half presses the chips against the other mold half to slightly compress the resilient contact elements; (b) wherein said covering compound is filled into said mold and cured in said mold; (c) said mold is removed after said covering compound is cured; and (d) said plurality of semiconductor chips with said resilient contact elements protruding on said one semiconductor chip side are separated by cutting said cured covering compound or by cutting said wafer.
