Claim:
A method for fabricating a feature including the deposition of a deposited material, comprising the steps of furnishing a substrate; thereafter depositing a liftoff layer overlying the substrate; thereafter depositing a hard-mask layer overlying the liftoff layer; thereafter depositing an image layer in registry with a retained portion of the hardmask layer, leaving a nonretained portion of the hard-mask layer which is not in registry with the image layer; thereafter removing the nonretained portion of the hard-mask layer; removing at least a part of the thickness of the image layer; removing a nonretained portion of the liftoff layer and an undercut portion of the liftoff layer that is less than all of the liftoff layer that lies in registry with the retained portion of the hard-mask layer; thereafter depositing the deposited material onto the substrate from a source; and thereafter removing the retained portion of the hard-mask layer and any part of the liftoff layer remaining between the hard-mask layer and the substrate.
