Abstract:
A first mask and a second mask are sequentially provided to perform a multi-step exposure and development processes. Through proper overlay design of the first mask and the second mask, conductive wirings having acceptable overlay offset are formed.

Claim (Index 1):
A method for fabricating conductive wirings, comprising:\n patterning a photoresist layer, comprising:\n providing a first mask comprising a first layout pattern; \n performing a first exposure process via a first mask and a first development process to form a plurality of first wiring openings in a first portion of the photoresist layer, and the first portion of the photoresist layer being covered by the first mask; \n providing a second mask comprising a second layout pattern; \n performing a second exposure process via a second mask and a second development process to form a plurality of second wiring openings in a second portion of the photoresist layer, an overlay portion of the first portion and the second portion of the photoresist layer being covered by the second mask, the first wiring openings and the second wiring openings being communicated at the overlay portion, and the second layout pattern of the second mask being substantially aligned with the first wiring openings formed in the photoresist layer when performing the second exposure process; and \n forming the conductive wirings in the first wiring openings and the second wiring openings.
