Patent ID: 7182875

Claim:
A method for fabricating a microstructure, comprising: providing a substrate having a patterned sacrificial polymer material layer disposed thereon, said patterned sacrificial polymer layer comprising at least a first distinct portion and a second distinct portion; disposing a framing material layer over said at least first and second distinct portions such that said framing material layer engages the sacrificial material of each distinct portion; disposing a non-sacrificial overcoat layer over said framing material layer such that said overcoat layer is substantially separated from the sacrificial material of said at least first and second distinct portions by said framing material layer, said overcoat layer is selected from polynorbornenes, epoxides, polyarylene ethers, parylenes and combinations thereof; and removing the sacrificial polymer material from said at least first and second distinct portions via thermal decomposition such that microstructures are formed.
