Abstract:
Techniques for bond pad fabrication are provided. In one aspect, a method of forming a bond pad comprises the following steps. At least one alloying element is selectively introduced to at least a portion of at least one surface of the bond pad. The at least one alloying element is diffused into at least a portion of the bond pad through one or more thermal cycles. The at least one alloying element may be selectively introduced to the bond pad by depositing an alloying element layer comprising the at least one alloying element onto the bond pad and patterning and etching at least a portion of the layer.
