Abstract
The present invention provides a method for fabricating bulbous-shaped vias on a substrate, having a surface, by disposing, on the substrate, a polymerizable fluid composition. A mold is placed in contact with the polymerizable fluid composition. The mold includes a relief structure on a surface thereof to create a recess in a layer of the polymerizable fluid composition. The polymerizable fluid composition is subjected to conditions to cause polymerization, forming a polymerized layer having a solidified indentation. An opening to the surface of the substrate is formed by removing material disposed on the substrate surface through etch processes. In a further embodiment a conductive layer may be disposed in the opening to form a gate. A lift-off process may be employed to remove the polymerized layer.
