Abstract

A method of forming a dielectric between memory cells in a device includes forming multiple memory cells, where a gap is formed between each of the multiple memory cells. The method further includes performing a high density plasma deposition (HDP) process to fill at least a portion of the gap between each of the multiple memory cells with a dielectric material.
