Abstract of the DisclosureMethod of producing semiconductor integrated circuits includes etching away regions of the semiconductor wafer so as to leave spaced apart electrically functionary semiconductor pieces that are to function as semiconductor devices and as interconnections in the ultimate circuit, and filling the space between the pieces with solidifying insulating material to mechanically interconnect the pieces. Prior to etching, the semiconductor wafer is cemented onto an acid-resistant carrier, and the etching and filling steps are performed while the wafer is mounted on the carrier. After solidification of the filled and insulated material the carrier is removed. |
