Abstract:
A method includes performing an implantation on a portion of a first layer to form an implanted region, and removing un-implanted portions of the first layer. The implanted region remains after the un-implanted portions of the first layer are removed. An etching is then performed on a second layer underlying the first layer, wherein the implanted region is used as a portion of a first etching mask in the etching. The implanted region is removed. A metal mask is etched using the second layer to form a patterned mask. An inter-layer dielectric is then etched to form a contact opening, wherein the patterned mask is used as a second etching mask.

Claim (Index 11):
The method of  claim 9 , wherein the transferring openings in the mask layer into the underlying inter-layer dielectric comprises:\n etching a metal hard mask layer underlying the mask layer, wherein the mask layer is used as an etching mask; and etching the inter-layer dielectric using the metal hard mask layer as an etching mask.
