Abstract
An electrically programmable element is fabricated in a P-N junction isolated region of a semiconductor body by first extending the depth of the region in the body by introducing dopants through the region into the body by ion implantation or by diffusion and drive-in, and thereafter forming an amorphotized layer in the first region overlying the extended portion. The increased depth of the first region provided by the second region prevents damage to the P-N junction between the semiconductor body and the first region during formation of the amorphotized layer.
