Patent ID: 7964476

Claim:
A method for fabricating a semiconductor device, said method comprising the steps of: providing a substrate; depositing a body of a first electrode material on said substrate; scribing said body of first electrode material so as to form a plurality of spaced apart, electrically isolated portions of said body of first electrode material; depositing a body of semiconductor material in a superposed relationship with said scribed, first electrode; depositing a second electrode in a superposed relationship with said semiconductor body; laser scribing said second electrode with a laser having an output wavelength of 300 nanometers or less; and illuminating at least one selected portion of said second electrode with a laser beam so as to form an electrically conductive channel through the body of semiconductor material, said channel having an electrical resistivity which is lower than the electrical resistivity of the remainder of said semiconductor body, said channel extending between said first and second electrodes.
