    摘要: Methods for providing a silicon layer on a photomask substrate surface with minimum defeats for fabricating film stack thereon for EUVL applications are provided. In one embodiment, a method for forming a silicon layer on a photomask substrate includes performing an oxidation process to form a silicon oxide layer on a surface of a first substrate wherein the first substrate comprises a crystalline silicon material, performing an ion implantation process to define a cleavage plane in the first substrate, and bonding the silicon oxide layer to a surface of a second substrate, wherein the second substrate is a quartz photomask.
