摘要: The method of forming a wordline is provided in the present invention. The proposed method includes steps of: (a) providing a plurality of SASTIs with a plurality of first POLY cells deposited thereon; and (b) depositing a first fill-in material having a relatively high etching rate oxide-like material in the plurality of SASTIs and on each side wall of the plurality of first POLY cells.

摘要: A method of manufacturing an integrated circuit with a small pitch comprises providing a second material layer patterned to form at least two features with an opening between the features. The second material layer is formed over a first material layer and the first material layer is over a substrate. The method also comprises providing a first oxide layer to form a first sidewall surrounding each of the features, and providing a second oxide layer over the first sidewalls and the first material layer. A second sidewall is formed surrounding each of the features. The method further comprises providing a conductive layer over the second oxide layer and removing the conductive layer, the second sidewalls and the first material underneath the second sidewalls.
