Abstract:
1. A method of depositing a cap layer on a substrate surface, comprising: (A) exposing the substrate surface to a first cleaning solution; after exposing the substrate surface to a first cleaning solution, spinning off the first cleaning solution without drying or dewetting the substrate surface, rinsing the substrate with deionized water, and spinning off excess liquid from the substrate without drying or dewetting the substrate surface; (B) after spinning off excess liquid from the substrate without drying or dewetting the substrate surface, exposing the substrate surface to a second cleaning solution; after exposing the substrate surface to a second cleaning solution, spinning off the second cleaning solution without drying or dewetting the substrate surface, rinsing the substrate with deionized water, and spinning off excess liquid from the substrate without drying or dewetting the substrate surface; and (C) after spinning off excess liquid from the substrate without drying or dewetting the substrate surface, depositing the cap layer on the substrate surface with an electroless deposition solution; wherein the substrate surface is not dried or dewetted from (A) through (C).
