Abstract:
Methods, apparatuses, and systems related to stack a semiconductor structure are described. An example method includes stacking a semiconductor structure between electrode materials 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 a third silicate material on the second nitride. The method further includes forming a third nitride on the third silicate material. The method further includes using a wet etch process to increase a width between electrode materials. The method further includes using a dry etch process to remove a portion of materials within the semiconductor structure.
