    摘要: The present application discloses a method for fabricating a semiconductor device including: providing a photomask including an opaque layer on a mask substrate and surrounding a translucent layer on the mask substrate; forming a pre-process mask layer on a device stack; patterning the pre-process mask layer using the photomask to form a patterned mask layer including a mask region corresponding to the opaque layer, a trench region corresponding to the translucent layer, and a via hole corresponding to the mask opening of via feature; performing a damascene etching process to form a via opening and a trench opening in the device stack; and forming a via in the via opening and a trench in the trench opening. The translucent layer includes a mask opening of via feature which exposes a portion of the mask substrate. A thickness of the trench region is less than a thickness of the mask region.
