Abstract:
1. A method for patterning one or more surface regions using a mask-less process, the method comprising: providing a substrate including a surface region, the surface region having a thickness of particle sensitive material overlying the surface region, the thickness of particle sensitive material having a surface topography; suspending a head member including a particle source and an air bearing region over a spatial portion of the surface topography of the thickness of particle sensitive material provided on the surface region of the substrate; moving the surface region including the particle sensitive material relative to the head member including the particle source to cause an air flow between the air bearing region and a portion of the surface topography to create a lifting force using at least the air bearing region as the air bearing region moves relative to the surface topography of the particle sensitive material, while the head member being suspended by a suspension member coupled to the head member; selectively exposing one or more portions of the particle sensitive material using the particle source provided on the head member while the particle sensitive material is being moved relative to the head member to form one or more exposed patterns on the particle sensitive material.
