A structure. The structure may include a layer of cobalt disilicide that is substantially free of cobalt monosilicide and there is substantially no stringer of an oxide of titanium on the layer of cobalt disilicide. The structure may include a substrate that includes: an insulated-gate field effect transistor (FET) that includes a source, a drain, and a gate; a first layer of cobalt disilicide on the source, said first layer having substantially no cobalt monosilicide, and said first layer having substantially no stringer of an oxide of titanium thereon; a second layer of cobalt disilicide on the drain, said second layer having substantially no cobalt monosilicide having substantially no stringer of an oxide of titanium thereon; and a third layer of cobalt disilicide on the gate, said third layer having substantially no cobalt monosilicide and having substantially no stringer of an oxide of titanium thereon.
