Claim 1
Independent Claim
122 words
THE METHOD OF FORMING A PLANAR DIODE WHICH COMPRISES: (A) APPLYING A MASKING MATERIAL TO A RELATIVELY SMALL SURFACE OF A WATER COMPRISING A DOPED MONOCRYSTAL OF A SEMICONDUCTOR MATERIAL, (B) CONTACTING SURFACES OF SAID WATER WITH DISPERSE MOLECULES OF A HALIDE OF A GLASS-FORMING METAL SELECTED FROM GROUPS III, IV, AND V OF THE PERIODIC TABLE, (C) HYDROLYZING SAID METAL HALIDE MOLECULES WITH WATER VAPOR TO FORM A GLASS-LIKE OXIDE FILM ADHERENT TO SAID EXTERIOR SURFACE INCLUDING SAID MASKED SURFACE, (D) REMOVING SAID MASKING MATERIAL AND ADHERENT FILM TO FORM A COATING FREE SURFACE, AND (E) DIFFUSING A DOPING MATERIAL INTO THE WATER AT SAID SURFACE TO FORM A PN JUNCTION, THE EDGES OF WHICH EXTEND UNDER THE SAID GLASS-LIKE FILM.
