Abstract:
An etch process that includes removing an oxide containing surface layer from a semiconductor surface to be etched by applying a hydrofluoric (HF) based chemistry, wherein the hydrofluoric (HF) based chemistry terminates the semiconductor surface to be etched with silicon-hydrogen bonds, and applying a vapor priming agent bearing chemical functionality based on the group consisting of alkynes, alcohols and a combination thereof to convert the silane terminated surface to a hydrophobic organic surface. The method continues with forming a photoresist layer on the hydrophobic organic surface; and patterning the photoresist layer. Thereafter, the patterned portions of the photoresist are developed to provide an etch mask. The portions of the semiconductor surface exposed by the etch mask are then etched.

Claim (Index 7):
The method of  claim 1 , wherein said vapor priming agent bearing chemical functionality based on alkynes to convert the silane terminated surface to a hydrophobic organic surface comprises an alkyne selected from the group consisting of 5-chloro-1-pentyne, Propargyl ether, Iodo-1-pentyne, 5-Hexynoic acid, 1,7-Octadiyne, Ethyl propiolate, Dimethyl propargylmalonate, Methyl propiolate, Hexyne, 1-Octyne, and combinations thereof.
