Abstract
A programmable semiconductor integrated circuitry including a circuit programming element is disclosed. The circuit programming element can be activated in a short-circuit mode by the irradiation of a laser or electron beam or by ion implantation so that it is converted from its original nonconductive state into a conductive or conductable state, thereby providing electrical connection between circuits and/or circuit elements of the integrated circuitry for a desired circuit programming such as circuit creation, circuit conversion or circuit substitution.
