The fabrication of ultracompact three dimensional monolithic microwave circuits (MMIC) having a sophisticated three-dimensional (3D) interconnection structure was discussed. The circuits were manufactured using the inductively coupled plasma etching with a double-layer mask, consisting of WSi covered with photoresists containing silicon. The developed method enabled the formation of holes to any levels of interconnections simultaneously. It resulted in smaller chip area, higher performance and greater design flexibility in MMICs.
