Methods, apparatuses, and systems related to trim a semiconductor structure using oxygen are described. An example method includes forming a support structure for a semiconductor structure having a first silicate material on a working surface. The method further includes forming a first nitride material on the first silicate material. The method further includes forming a second silicate material on the first nitride material. The method further includes forming a second nitride material on the second silicate material. The method further includes forming an opening through the semiconductor structure. The method further includes depositing an electrode material within the opening. The method further includes removing portions of the support structure. The method further includes performing a controlled oxidative trim to an upper portion of the electrode material.

Oxidative trim

A method used to form a semiconductor device provides a silicide layer on a plurality of transistor word lines and on a plurality of conductive plugs. In one embodiment, the word lines, one or more sacrificial dielectric layers on the word lines, conductive plugs, and a conductive enhancement layer are formed through the use of a single mask. An in-process semiconductor device which may be formed using one embodiment of the inventive method is also described.
