Abstract

Customizable semiconductor/devices, integrated circuit gate arrays and techniques to produce same are disclosed. The devices comprise integrated circuit blanks having a collection of semiconductor elements and at least one metal layer including fusible links interconnecting said collection of semiconductor elements into an inoperably connected integrated circuit blank. At least one metal layer is first etched thereby to define a pattern of conductors. A passivation layer is provided over at least one metal layer, afterwhich at least one metal layer is etched a second time for selectably removing the fusible links, thereby converting the inoperable integrated circuit blank into a selected operable electronic function.
