Abstract

An edge defining method is employed in the fabrication of narrow electrical patterns for VLSI circuits. The method is particularly employable in the formation of inlay MOSFET transistors having extremely narrow gate widths. The method is also particularly amenable to the fabrication of both symmetrical and non-symmetrical MOSFET devices on the same VLSI circuit chip. The inlay transistor structure is also employed to fabricate NOR and NAND type "ladder" networks and to join vertically and horizontally adjacent semiconductor devices.
