发明名称 Method of forming an electrical connection
摘要 The present invention relates to high aspect-ratio electrical connections, wiring trenches, and methods of forming the same in semiconductor devices. In particular, the present invention relates to formation of contacts with refractory metal and/or refractory metal nitride liners that assist in filling of the contacts. Additionally disclosed is the combination of shallow junction fabrication and high aspect-ratio contact formation to form contacts between a shallow junction and microcircuitry wiring. More particularly, the present invention relates to aluminum filled contacts that fill contact corridors, trenches, or vias in semiconductor devices that are initially lined with a titanium layer and at least one other layer. Preferred other layers include CVD, PVD, or reacted TiN, Co, Ge, and Si.
