Etching platinum-containing thin film using protective cap layer
A microelectronic device is formed by forming a platinum-containing layer on a substrate of the microelectronic device. A cap layer is formed on the platinum-containing layer so that an interface between the cap layer and the platinum-containing layer is free of platinum oxide. The cap layer is etchable in an etch solution which also etches the platinum-containing layer. The cap layer may be formed on the platinum-containing layer before platinum oxide forms on the platinum-containing layer. Alternatively, platinum oxide on the platinum-containing layer may be removed before forming the cap layer. The platinum-containing layer may be used to form platinum silicide. The platinum-containing layer may be patterned by forming a hard mask or masking platinum oxide on a portion of the top surface of the platinum-containing layer to block the wet etchant.
