Patent ID: 7060613

Claim:
A method of patterning a solid Ni(CO) 4 layer, comprising the steps of: providing a substrate having a solid Ni(CO) 4 layer formed thereover; forming a partial chrome photoresist layer over the solid Ni(CO) 4 layer; the partial chrome photoresist layer having a chrome portion and a non-chrome portion; and exposing the partial chrome photoresist layer with radiation that penetrates only the non-chrome portion of the photoresist layer to the underlying solid Ni(CO) 4 layer whereby the temperature of the radiation exposed portion of the solid Ni(CO) 4 layer is increased to above 40° C. so that the radiation exposed portion of the solid Ni(CO) 4 layer decomposes so that the solid Ni(CO) 4 layer is patterned.
