CONTACTS TO SHALLOW P-N JUNCTIONS Abstract Deep penetration spikes, when a fused metal contact is made to semiconductor material, can be avoided by converting a portion of exposed crystalline semiconductor material to a layer of amorphous semiconductor material. The converted portion is the volume of the semiconductor material required to saturate the metal during a post-metallization annealing step. Y0978-004
