Patent ID: 7307027

Claim:
A method of forming a dielectric between memory cells in a device, comprising: forming a plurality of memory cells, wherein a gap is formed between each of the plurality of memory cells; performing a high density plasma deposition (HDP) process to fill at least a portion of the gap between each of the plurality of memory cells with a dielectric material that is substantially free of voids, wherein the HDP process comprises providing SiH 4 at a flow rate ranging from about 10 standard cubic centimeters per minute to about 1,000 standard cubic centimeters per minute, and providing PH 3 at a flow rate ranging from about 10 standard cubic centimeters per minute to about 1,000 standard cubic centimeters per minute, for a period ranging from about 1 second to about 1,000 seconds; forming a liner layer over the plurality of memory cells prior to performing the HDP process, wherein the liner layer comprises at least one of silicon nitride or silicon oxynitride; and planarizing the dielectric material.
