Patent ID: 7344928

Claim:
A method for manufacturing an electrical component on a substantially transparent substrate comprising the steps of: depositing a first metal layer over at least a portion of the transparent substrate; depositing a first masking material layer over at least a portion of said first metal layer by digital lithography to thereby form a first patterned etch mask; removing said first metal layer, except in the regions underlying said first patterned etch mask, to thereby form source and drain electrodes; removing said first patterned etch mask; depositing a semiconductive layer over at least a portion of the transparent substrate and said source and drain electrodes; depositing an insulative layer over at least a portion of said semiconductive layer; depositing a layer of photosensitive material over at least a portion of said insulative layer; exposing the layer of photosensitive material to radiation by directing said radiation initially through the transparent substrate, such that said source and drain electrodes serve to mask said radiation from exposing portions of said photosensitive material layer; developing said layer of photosensitive material such that such material exposed to said radiation is removed and such material not exposed to said radiation remains over a portion of said insulative layer; depositing a second metal layer over at least a portion of said insulative layer and said remaining photosensitive material; depositing a second masking material layer onto at least a portion of said second metal layer by digital lithography to thereby form a second patterned etch mask; removing said second metal layer, said insulative layer, and said semiconductive layer, etching, except in the regions underlying said second patterned etch mask; removing said second patterned etch mask; and removing said remaining photosensitive material, such that the mechanical connection of regions of said second metal layer deposited directly thereover are weakened sufficiently that said regions physically disconnect from the remainder of said second metal layer and may be removed.
