Title: Methods and apparatus for forming submicron patterns on films

Patent ·
OSTI ID:1531505

A method for forming a patterned film on a substrate, the method including: providing a first flowable medium on the substrate and a second flowable medium on the first flowable medium, the first and second flowable media having different dielectric properties and defining an interface there between; applying an electric field to the interface for a time sufficient to produce a structure in the first flowable medium along the interface: and hardening the structure in the first flowable medium to form the patterned film.
