Abstract

1,183,150. Semi-conductor devices. HUGHES AIRCRAFT CO. 13 March, 1968 [17 April, 1967]. No. 12190/68. Heading H1K. In an IGFET having spaced source and drain regions of opposite conductivity type to the substrate the gate electrode is disposed over part only of the channel region between the source and drain and a surface region contiguous with the drain extends along part of the channel not covered by the gate electrode. The device is produced by oxidizing the surface of an N-type silicon wafer 2, masking and etching to leave a peripheral strip 5 and an annular region (6) of oxide, Figs. 1 and 2 (not shown), diffusing-in boron from the vapour phase to form P-type source and drain regions 10, 12, Fig. 3 (not shown), removing the annular mask and forming a fresh thin oxide layer 61 over the surface, vapour depositing Al, Cr or Au over the surface and masking and etching, or alternatively depositing a metal through a mechanical mask, to form an annular gate electrode 14 covering the outer part of the channel between the peripheries of the diffused source and drain regions 10, 12, Fig. 4 (not shown), forming a P-type region 16 in the remainder of the channel by ion implantation, the remainder of the wafer being protected by the edge of the gate electrode and a mechanical mask, Figs. 5 and 6 (not shown), and exposing parts of the source and drain regions 10, 12 and depositing Al to form source and drain electrodes 19, 21, Fig. 7. The gate electrode 14 has an extension (141) to the edge of the wafer where it overlies a tab (51) extending from the original peripheral oxide mask (5) to provide a gate electrode bonding pad, Fig. 4 (not shown). The source and drain electrodes may be formed simultaneously with the gate electrode.
