摘要:
A method of fabricating an interconnect structure, comprising exposing an empty deposition chamber to a process that includes generating reactive species produced from a source gas in the presence of a plasma. The method further comprises terminating the plasma and then introducing a semiconductor substrate with a metal layer thereon into the chamber while the reactive species are present in the chamber.
摘要:
A method of manufacturing a semiconductor device includes the steps of providing a semiconductor substrate (202), forming a dielectric layer (204) over the semiconductor substrate (202), and etching a trench or a via (206) in the dielectric layer (204) to expose a portion of the surface of the semiconductor substrate (202). The method also includes the step of forming a conductive layer (212, 220) within in the trench or the via (206). The method further includes the steps of polishing a portion of the conductive layer (220) and annealing the conductive layer (212, 220) at a predetermined temperature. Moreover, the conductive layer (212, 220) also includes a dopant, and the dopant diffuses substantially to the surface of the top side of the conductive layer (212, 220) to form a dopant oxide layer (212a, 220a) when the conductive layer (212, 220) is annealed at the predetermined temperature and the dopant is exposed to oxygen.
摘要:
Disclosed is a system for fabricating a semiconductor device (100). An interconnect structure (110) is formed on the semiconductor device (100) and a cap (112) is deposited over the interconnect structure (110). The interconnect structure (110) is annealed with the overlying cap (112) in place. The cap (112) is then removed after the interconnect structure (110) is annealed.
摘要:
A method of forming an integrated circuit including an organosilicate low dielectric constant insulating layer (40) formed of a substitution group depleted silicon oxide, such as an organosilicate glass, is disclosed. Subsequent plasma processing has been observed to break bonds in such an insulating layer (40), resulting in molecules at the surface of the film with dangling bonds. Eventually, the damaged insulating layer (40) includes silanol molecules, which results in a degraded film. The disclosed method exposes the damaged insulating layer (40) to a thermally or plasma activated fluorine, hydrogen, or nitrogen, which reacts with the damaged molecules to form a passivated surface for the insulating layer (40).

摘要:
According to one embodiment of the invention, a method for forming multiple layers of a semiconductor device is provided. The method includes defining a via through a dielectric layer that overlies a first layer. The first layer comprises a conductive portion that at least partly underlies the via. The method also includes overfilling the via with a dielectric material to form a second layer that overlies the dielectric layer. The method also includes forming a trench that is connected to the via by etching through the second layer and the dielectric material in the via.
