  • Method of fabricating an integrated circuit having active regions near a die edge
    Patent number: 5196378
    Abstract: The invention relates to a method of scribing and separating dice from each other after fabrication in a semiconductor wafer in a manner such that active circuit regions in the dice reside as near to an edge of a die as possible. The wafer is anistropically etched through the active layer and into the substrate through an opening in the mask to form a generally V-shaped channel with the dice then being separated along a vertex of the channel. The dice are then positioned to abut each other in the form of a mosaic.
