摘要:
In one exemplary embodiment of the invention, a method (e.g., to fabricate a semiconductor device having a borderless contact) including: forming a first gate structure on a substrate; depositing an interlevel dielectric over the first gate structure; planarizing the interlevel dielectric to expose a top surface of the first gate structure; removing at least a portion of the first gate structure; forming a second gate structure in place of the first gate structure; forming a contact area for the borderless contact by removing a portion of the interlevel dielectric; and forming the borderless contact by filling the contact area with a metal-containing material.
