Abstract
1412904 Semiconductor devices SONY CORP 1 Aug 1973 [25 April 1973] 36625/73 Heading H1K The mesh-shaped gate region 15 of a junctiongate f.e.t. is covered by a correspondingly shaped insulating layer 16 which surrounds discrete highly-doped source regions 17 in the holes of the mesh. The regions 17 are interconnected by a common source electrode 20 overlying the insulation 16. The p<SP>+</SP> gate region 15 is preferably formed by diffusion into a mesh-shaped recess etched through a silicon nitride, molybdenum or silicon nitride-on-oxide mask on the n- Si body 10, which ultimately forms the drain region and may have on its lower surface a diffused or epitaxial n<SP>+</SP> layer 13. The insulation 16 is then formed by localized oxidation through slightly enlarged apertures of the same mask (for the nitride-on-oxide mask the enlargement of the apertures may be effected only in the lower, oxide layer by wider-etching the upper, nitride layer). In the form shown an n<SP>+</SP> ring surrounds the insulation 16, but in two modifications this feature is lacking, being replaced in one case by an extension of the gate electrode 21 so as to overlap the outer periphery of the junction between the gate region 15 and the substrate 10 and in the other case by a peripheral capacitive field electrode connected to the source electrode 20.
