Abstract
The present disclosure relates a method of manufacturing an integrated chip structure. The method forms an intermediate first material layer over a substrate and an intermediate second material layer on the intermediate first material layer. The intermediate second material layer is patterned to form an insulating layer. The intermediate first material layer is patterned to form a first material layer having an outermost sidewall indented inward from an outermost sidewall of the insulating layer. An ion bombardment process is performed on the insulating layer to dislodge one or more atoms from the insulating layer. A re-deposition process is performed to re-deposit the one or more atoms onto the outermost sidewall of the first material layer and to form a self-filling spacer below the insulating layer.
