Patent ID: 6916720

Claim:
A method for fabricating a thin film device, comprising the steps of: applying a first photoresist layer to a first surface; patterning the first photoresist layer to have at least a first opening in the first photoresist layer, wherein the first opening exposes the first surface; depositing a film onto the first photoresist layer, wherein a portion of the deposited film is deposited onto the exposed first surface; applying a second photoresist layer onto the deposited layer; patterning the second photoresist layer, wherein the second photoresist layer remains applied to the portion of the deposited film within the first opening and covers a second portion of the deposited layer; selectively removing the deposited layer, wherein the second photoresist layer substantially prevents the removal of the second portion of the deposited layer, wherein the first photoresist layer and the second photoresist layer assist in the defining of the deposited layer; removing the first photoresist layer and the second photoresist layer, therein exposing the first surface and the second portion of the deposited layer; applying a third photoresist layer; patterning the third photoresist layer to have at least a second opening in the third photoresist layer; depositing a second film onto the third photoresist layer, wherein a portion of the deposited second film is deposited within the second opening; applying a fourth photoresist layer onto the deposited layer; patterning the fourth photoresist layer, wherein the fourth photoresist layer remains applied to the portion of the deposited second film within the second opening and covers a second portion of the deposited second layer; selectively removing the deposited second layer, wherein the fourth photoresist layer substantially prevents the removal of the second portion of the deposited second layer, wherein the third photoresist layer and the fourth photoresist layer assist in the defining of the deposited second layer; and removing the third photoresist layer and the fourth photoresist layer.
