Patent ID: 7011985

Claim:
A method for producing miniature amplifier and signal processing unit comprising the steps of: producing arrays of individual integrated circuits on a side of a wafer ( 5 ), where each circuit has a number of I/O connection points; providing a number of solder connection pads ( 7 ) at each integrated circuit for redistribution of the I/O connection points of the integrated circuit; coating the side of the wafer having the solder connection pads ( 7 ) with a coating of protection material ( 9 ) and ensuing through going apertures ( 8 ) in the coating to provide electrical contact with the solder connection pads ( 7 ); applying electrical components ( 2 ) onto the coating and gaining electrical contact with the solder connection pads ( 7 ) through the apertures ( 8 ) of the coating material ( 9 ); fastening the wafer ( 5 ) to a carrier layer, singulating the individual amplifiers from the wafer ( 5 ) by providing furrows along the edges of each amplifier through the thickness of the wafer and ensuring protection of the edges of the amplifiers while individual amplifiers remain fastened to the carrier layer.
