    摘要: Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.

    摘要: An in-situ, two step or combination, method and system for cleaning of semiconductor manufacturing equipment is provided. The present invention utilizes two separate fluorine based chemistries in each step which selectively target the removal of different types of deposits that build up on the equipment surfaces. In particular, powdery and dense film-like solid deposits, as well as a combination of both, build up on the chamber surfaces and associated equipment components. These two types of deposits are removed selectively by the present invention. Such selective targeting of combined cleaning steps, yields an improved cleaning technique. In another embodiment, the method and system of the present invention provides for cleaning of the chamber and associated equipment using separate steps with different chemicals, and then performing these steps in a variety of desired sequences.

    摘要: Methods of etching exposed silicon on patterned heterogeneous structures is described and includes a remote plasma etch formed from a fluorine-containing precursor and a hydrogen-containing precursor. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents react with the exposed regions of silicon. The plasmas effluents react with the patterned heterogeneous structures to selectively remove silicon while very slowly removing other exposed materials. The silicon selectivity results, in part, from a preponderance of hydrogen-containing precursor in the remote plasma which hydrogen terminates surfaces on the patterned heterogeneous structures. A much lower flow of the fluorine-containing precursor progressively substitutes fluorine for hydrogen on the hydrogen-terminated silicon thereby selectively removing silicon from exposed regions of silicon. The methods may be used to selectively remove silicon far faster than silicon oxide, silicon nitride and a variety of metal-containing materials.

    摘要: Methods of forming silicon oxide layers are described. The methods include mixing a carbon-free silicon-containing precursor with a radical-nitrogen precursor, and depositing a silicon-and-nitrogen-containing layer on a substrate. The radical-nitrogen precursor is formed in a plasma by flowing a hydrogen-and-nitrogen-containing precursor into the plasma. Prior to depositing the silicon-and-nitrogen-containing layer, a silicon oxide liner layer is formed to improve adhesion, smoothness and flowability of the silicon-and-nitrogen-containing layer. The silicon-and-nitrogen-containing layer may be converted to a silicon-and-oxygen-containing layer by curing and annealing the film. Methods also include forming a silicon oxide liner layer before applying a spin-on silicon-containing material.

    摘要: Methods, materials, and systems are described for forming conformal dielectric layers containing silicon and nitrogen (e.g., a silicon-nitrogen-hydrogen (Si—N—H) film) from a carbon-free silicon-and-nitrogen precursor and radical-nitrogen precursor. The carbon-free silicon-and-nitrogen precursor is predominantly excited by contact with the radical-nitrogen precursor. Because the silicon-and-nitrogen film is formed without carbon, the conversion of the film into hardened silicon oxide is done with less pore formation and less volume shrinkage. The deposited silicon-and-nitrogen-containing film may be wholly or partially converted to silicon oxide which allows the optical properties of the conformal dielectric layer to be selectable. The deposition of a thin silicon-and-nitrogen-containing film may be performed at low temperature to form a liner layer in a substrate trench. The low temperature liner layer has been found to improve the wetting properties and allows flowable films to more completely fill the trench.
