Abstract:
A substrate processing method for forming a self-aligned contact using selective SiO 2  deposition is described in various embodiments. The method includes providing a planarized substrate containing a dielectric layer surface and a metal-containing surface, coating the dielectric layer surface with a metal-containing catalyst layer, and exposing the planarized substrate to a process gas containing a silanol gas for a time period that selectively deposits a SiO 2  layer on the metal-containing catalyst layer on the dielectric layer surface. According to one embodiment, the method further includes depositing an etch stop layer on the SiO 2  layer and on the metal-containing surfaces, depositing an interlayer dielectric layer on the planarized substrate, etching a recessed feature in the interlayer dielectric layer and stopping on the etch stop layer above the metal-containing surface, and filling the recessed feature with a metal.

Claim (Index 20):
The method of  claim 18 , wherein the SiO 2  layer forms a raised SiO 2  feature adjacent the metal-containing surface.
