Patent ID: 8748313

Claim:
A method for making a mask for semiconductor manufacturing, the method comprising: providing a base layer; forming a conductive layer on the base layer; forming a photoresist layer on the conductive layer; exposing selectively the photoresist layer to an energy illumination; developing the photoresist layer by removing a first portion of the photoresist layer; depositing a metal layer by an electroforming process, wherein the electroforming process includes submerging the conductive layer into a chemical bath, applying a deposition voltage across a negative electrode and a positive electrode, the positive electrode electrically connected to the chemical bath, the negative electrode electrically connected to the conductive layer; removing a second portion of the photoresist layer; and removing a first portion of the conductive layer, the first portion being substantially free from a protection of the metal layer, wherein the conductive layer comprises an indium tin oxide species.
