ABSTRACT:
A semiconductor device having a specific contact angle for immersion lithography is disclosed. The semiconductor device includes a substrate and a top layer disposed on the substrate. The top layer used in an immersion lithography process includes a composition such that a fluid droplet that occurs during the immersion lithographic process and is not part of an exposure fluid puddle, will have a contact angle between about 40° and about 80° with a surface of the top layer.
