Patent ID: 7498119

Claim:
A method of forming a structure, comprising the steps of: depositing over a substrate a photoresist layer; exposing the photoresist layer such that the solubility of substantially all of the photoresist layer is altered; depositing a phase change material over the photoresist layer; the phase change material deposited using a printing system comprising a printhead; the printhead including at least one ejector for ejecting the phase change material in liquid phase; the phase change material deposited in a printed pattern such that the printed pattern remains following a change from liquid phase to solid phase of the phase change material; and removing the photoresist layer except in a region underlying the printed pattern of phase change material and a portion but not all of the photoresist layer underlying the printed pattern of phase change material; such that a fine feature of photoresist layer is formed over the substrate, whose width is less than the width of that portion of the phase change material originally located thereover.
