    摘要: Methods of depositing a silicon oxide layer on a substrate are described. The methods may include the steps of providing a substrate to a deposition chamber, generating an atomic oxygen precursor outside the deposition chamber, and introducing the atomic oxygen precursor into the chamber. The methods may also include introducing a silicon precursor to the deposition chamber, where the silicon precursor and the atomic oxygen precursor are first mixed in the chamber. The silicon precursor and the atomic oxygen precursor react to form the silicon oxide layer on the substrate, and the deposited silicon oxide layer may be annealed. Systems to deposit a silicon oxide layer on a substrate are also described.

    摘要: A method of improving pattern loading in a deposition of a silicon oxide film is described. The method may include providing a deposition substrate to a deposition chamber, and adjusting a temperature of the deposition substrate to about 250° C. to about 325° C. An ozone containing gas may be introduced to the deposition chamber at a first flow rate of about 1.5 slm to about 3 slm, where the ozone concentration in the gas is about 6% to about 12%, by wt. TEOS may also be introduced to the deposition chamber at a second flow rate of about 2500 mgm to about 4500 mgm. The deposition rate of the silicon oxide film is controlled by a reaction rate of a reaction of the ozone and TEOS at a deposition surface of the substrate.

    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.
