Method of producing semi-conductor electrode systems

Claim 1

IN THE MANUFACTURE OF A SEMICONDUCTOR DEVICE COMPRISING PROVIDING A SEMICONDUCTOR BODY HAVING AN ELECTRODE PORTION PROTRUDING FROM THE SURFACE OF THE SEMICONDUCTOR BODY, THE METHOD OF SELECTIVELY REMOVING SURFACE PORTIONS OF THE BODY LEAVING INTACT A SURFACE PORTION ADJACENT THE ELECTRODE, COMPRISING THE STEPS OF COVERING THE SAID SURFACE AND ELECTRODE WITH A MASKING LAYER PROVIDING MEANS CAPABLE OF REMOVING THE MASKING LAYER WHEN CONTACTING SAME, PROJECTING THE SAID REMOVAL MEANS AT THE SURFACE ALONG A DIRECTION AND AT SUCH A LOW ANGLE TO THE SURFACE THAT THE PROTRUDING ELECTRODE PORTION SHADWOS THE ADJACENT PORTION OF THE MASKING LAYER, COEXTENSIVE WITH THE SURFACE PORTION TO REMAIN INTACT, AND PROTECTS IT FROM CONTACT WITH THE REMOVAL MEANS WHILE THE REMAINING UNSHADOWED AND UPROTECTED MASKING LAYER PORTIONS ARE CONTACTED AND REMOVED EXPOSING SURFACE PROTIONS OF THE BODY, AND THEREAFTER SUBBJECTING THE SAID BODY WITH THE MASKED SURFACE PORTION TO A TREATMENT CAPABLE OF REMOVING EXPOSED BODY PROTION TO REMOVE SAID EXPOSED PORTIONS OF THE BODY RESULTING IN A RAISED BODY PORTION ON WHICH IS LOCATED THE ELECTRODE.
