Abstract

A stack of layers providing an ohmic contact with the semiconductor, a lower metal layer of the stack is disposed in direct contact with the semiconductor; and a radiation absorption control layer disposed over the lower layer for controlling an amount of the radiant energy to be absorbed in the radiation absorption control layer during exposure of the stack to the radiation during a process used to alloy the stack with the semiconductor to form the ohmic contact.
