Robert Noyce devised a semiconductor device structure that integrates electrical connections with the semiconductor surface. His patent places conducting paths over an insulating layer and connects them to selected regions through openings in that layer. This makes interconnection part of fabrication rather than requiring every connection to be a separate external wire. The design connects surface insulation, device junctions and patterned conductors in the development of the integrated circuit.[ref]
