摘要: A process of making an electrical coupling stack is disclosed. A conductive structure is coupled to a substrate. The coupling includes a crystalline salicide first structure above the conductive structure, a nitrogen-containing amorphous salicide second structure above the crystalline salicide first structure, and a refractory metal third film above the nitrogen-containing amorphous salicide second structure. Processing includes depositing a refractory metal silicide first film over the conductive structure, depositing a refractory metal nitride second film over the refractory metal silicide first film, and depositing the refractory metal third film over the refractory metal nitride second film. Thermal processing is carried out to achieve the electrical coupling stack.

摘要: A process of making a buried digit line stack is disclosed. The process includes forming a silicon-lean metal silicide first film over a polysilicon plug, followed by a silicide compound barrier second film. The silicide compound barrier second film is covered with a refractory metal third film. A salicidation process causes the first film to salicide with the polysilicon plug. In one embodiment, all the aforementioned deposition processes are carried out by physical vapor deposition (nullPVDnull).
