Patent ID: 7071088

Claim:
A method for fabricating vias on a substrate having a surface, comprising: disposing, adjacent to said substrate, a polymerizable fluid composition; contacting said polymerizable fluid composition with a mold having a relief structure, with said polymerizable fluid composition conforming to a profile of said mold; subjecting said polymerizable fluid composition to conditions to polymerize said polymerizable fluid composition, forming a polymerized layer having a bi-level indentation including a nadir and shoulders spaced-apart from said nadir; forming a relief pattern adjacent to said substrate having an opening extending toward said surface by selectively removing material adjacent to said substrate, with said material including a sub-section of said polymerized layer located proximate to said bi-level indentation; and depositing a conductive layer to cover said relief pattern, thereby forming a contact having a shape defined by said relief pattern.
