Claim Text:
1. A surface treatment method for a semiconductor device having capacitor patterns, comprising: providing a substrate, where projected capacitor patterns including a metal-containing material are formed, in a mold insulation layer; removing the mold insulation layer by using a wet etch solution; rinsing the substrate, from which the mold insulation layer is removed, with deionized water; treating the substrate, where the projected capacitor patterns are formed, with an SC-1 (NHOH+HO+OH) solution; rinsing the treated substrate with deionized water; forming a hydrophobic coating layer on a surface of each of the projected capacitor patterns; rinsing the substrate, where the hydrophobic coating layer is formed, with deionized water; and drying the substrate, wherein the hydrophobic coating layer is formed using a coating agent that includes phosphate, wherein the phosphonate has more than one hydrocarbon group, wherein each of the projected capacitor patterns is thinned during the treating the substrate with the SC-1 solution.
