Abstract

1380466 Semi-conductor devices RCA CORPORATION 30 March 1972 [12 July 1971] 14978/72 Heading H1K A gate insulation protection device for an insulated gate field effect transistor 42 comprises a plurality of degenerately doped back to back diodes, 70, formed in a semi-conductor film 50 disposed on insulating material 44. The diodes may be formed from nine degenerately doped regions 72, 74 of alternating conductivity type, forming eight Zener diodes connected in series between the gate electrode 63 and either the source or drain region 64, 66 respectively. The insulating material may be sapphire or spinel, the film 50 being of epitaxially deposited silicon 10,000Š thick. The degenerate doping level may be in excess of 5 + 10<SP>19</SP> atoms/cc. An insulating film 78 over the diodes may be thermally grown silicon dioxide, and aluminium conductive tracks used for interconnections. Doping may be by means of boron. In an alternative embodiment, the diodes are similarly formed on an insulating film on a semiconductor substrate in which the I.G.F.E.T. is formed. One connection to the diodes may be by means of a conductive track leading to a diffused region in the substrate.
