Claim 1
Independent Claim
83 words
THE METHOD OF SURFACE TREATMENT OF A SEMICONDUCTOR CRYSTAL BODY CONTAINING MOISTURE FOR USE IN A SEMICONDUCTOR SIGNAL TRANSLATING DEVICE WHICH COMPRISES THE STEPS OF ETCHING A SURFACE OF SAID SEMICONDUCTOR CRYSTAL BODY, MOISTENING SAID SURFACE, IMMERSING SAID SURFACE IN A SOLUTION OF WATER HYDROLYZABLE ORGANO-SUBSTITUTED SILANES INCLUDING A MONOFUNCTIONAL ORGANO SILANE, REMOVING SAID SILICON BODY FROM SAID SOLUTION, AND HEATING SAID BODY TO A PREDETERMINED TEMPERATURE SUFFICIENT TO BOIL OFF THE VOLATILE COMPOUNDS WHICH REMAIN AFTER THE POLYMERIZATION OF THE ORGANO-SUBSTITUTED SILANES.
