Abstract:
1. A method of making a radio frequency device comprising the steps of: providing a thin film substrate circuit; forming an interposer having a first contact pad and a second contact pad, wherein a pattern of first and second contact pads of the interposer is selected from a group consisting of butterfly, propeller, and bow-tie pattern with a gap between the pads; placing an integrated circuit chip on the interposer such that the integrated circuit chip is in contact with the first contact pad and the second contact pad of the interposer to form a subassembly; locating the interposer-chip subassembly over a portion of the thin film substrate circuit; and electrically connecting the integrated circuit chip to the thin film substrate circuit by placing the interposer-chip subassembly in contact with the substrate circuit, thereby securing the integrated circuit chip to at least the portion of the substrate circuit.
