    摘要: A method and apparatus that reduces the time required to clean a processing chamber employing a reactive plasma cleaning process. A plasma is formed in an Astron fluorine source generator from a flow of substantially pure inert-source gas. After formation of the plasma, a flow of a fluorine source gas is introduced therein such that the fluorine source flow accelerates at a rate no greater than 1.67 standard cubic centimeters per second2 (scc/s2). In this fashion, the plasma contains a plurality of radicals and dissociated inert-source gas atoms, defining a cleaning mixture. The ratio of inert-source gas to fluorine source is greater than 1:1.

    摘要: A method of etching a substrate comprises forming on the substrate, a plurality of double patterning features composed of silicon oxide, silicon nitride, or silicon oxynitride. The substrate having the double patterning features is provided to a process zone. An etching gas comprising nitrogen tri-fluoride, ammonia and hydrogen is energized in a remote chamber. The energized etching gas is introduced into the process zone to etch the double patterning features to form a solid residue on the substrate. The solid residue is sublimated by heating the substrate to a temperature of at least about 100° C.

    摘要: Aspects of the disclosure pertain to methods of depositing silicon oxide layers on substrates. In embodiments, silicon oxide layers are deposited by flowing a silicon-containing precursor having a Si—O bond, an oxygen-containing precursor and a second silicon-containing precursor, having both a Si—C bond and a Si—N bond, into a semiconductor processing chamber to form a conformal liner layer. Upon completion of the liner layer, a gap fill layer is formed by flowing a silicon-containing precursor having a Si—O bond, an oxygen-containing precursor into the semiconductor processing chamber. The presence of the conformal liner layer improves the ability of the gap fill layer to grow more smoothly, fill trenches and produce a reduced quantity and/or size of voids within the silicon oxide filler material.

    摘要: Processes for forming high density gap-filling silicon oxide on a patterned substrate are described. The processes increase the density of gap-filling silicon oxide particularly in narrow trenches. The density may also be increased in wide trenches and recessed open areas. The densities of the gap-filling silicon oxide in the narrow and wide trenches/open areas become more similar following the treatment which allows the etch rates to match more closely. This effect may also be described as a reduction in the pattern loading effect. The process involves forming then planarizing silicon oxide. Planarization exposes a new dielectric interface disposed closer to the narrow trenches. The newly exposed interface facilitates a densification treatment by annealing and/or exposing the planarized surface to a plasma.
