    摘要: A method of patterning a substrate. A sacrificial film is formed over a substrate and a pattern created therein. A first spacer layer is conformally deposited over the patterned sacrificial film and at least one horizontal portion of the first spacer layer is removed while vertical portions of the first spacer layer remain. A second spacer layer is conformally deposited over the patterned sacrificial film and the remaining portions of the first spacer layer. At least one horizontal portion of the second spacer layer is removed while vertical portions of the second spacer layer remain. Conformal deposition of the first and second spacer layers is optionally repeated one or more times. Conformal deposition of the first layer is optionally repeated. Then, one of the first or second spacer layers is removed while substantially leaving the vertical portions of the remaining one of the first or second spacer layers.

    摘要: A method is provided for forming a metal silicide layer on a substrate. According to one embodiment the method includes providing the substrate in a process chamber, exposing the substrate at a first substrate temperature to a plasma generated from a deposition gas containing a metal precursor, where the plasma exposure forms a conformal metal-containing layer on the substrate in a self-limiting process. The method further includes exposing the metal-containing layer at a second substrate temperature to a reducing gas in the absence of a plasma, where the exposing steps are alternatively performed at least once to form the metal silicide layer, and the deposition gas does not contain the reducing gas. The method provides conformal metal silicide formation in deep trenches with high aspect ratios.

The method includes: depositing a first spacer layer over a patterned structure, the first spacer layer having a seam propagating through a thickness of the first spacer layer near an interface region of a surface of the substrate and a sidewall of the patterned structure, etching the first spacer layer to form a residual spacer at the interface region, where the residual spacer coats less than the entirety of the sidewall of the patterned structure, depositing a second spacer layer on the residual spacer and on the sidewall of the patterned structure not coated by the residual spacer, the second spacer layer being seam-free on the seam of the residual spacer, and etching the second spacer layer to form a second spacer coating the residual spacer and coating the sidewall of the patterned structure not coated by the residual spacer.
