Method of enhancing selective deposition by cross-linking of blocking molecules

Abstract:

Methods of depositing a film selectively onto a first substrate surface relative to a second substrate surface are described. The methods include exposing a substrate to a blocking molecule to selectively deposit a blocking layer on the first surface. The blocking layer is exposed to a polymer initiator to form a networked blocking layer. A layer is selectively formed on the second surface. The blocking layer inhibits deposition on the first surface. The networked layer may then optionally be removed.
