    摘要: A method and system for assessing the ability of a securities processing system to apply straight through processing to securities transactions includes identifying one or more assessment issues in an issue and resolution log and capturing process and technology performance information for the securities processing system. The method also includes analyzing the process and technology performance information with respect to the one or more assessment issues and capturing information regarding the ability of at least one system external to the securities processing system to apply straight through processing to securities transactions. The method also includes formulating at least one recommendation, prioritizing the at least one recommendation, and developing an implementation plan.

    摘要: A method for removing carbon from or stripping a TERA layer. The method includes exposing the TERA layer to a plasma containing an effective amount of nitrogen, and, optionally, oxygen or fluorine. The method is compatible with fluorine based etching systems, and may thus be performed in the same etching system as other etching steps. For example, the method may be performed in the same system as a fluorine based plasma etch for oxide or nitride. The invention includes the method of stripping a TERA layer, etching an oxide layer, and etching a nitride layer in situ in the same etching system. The method is performed at low ion energies to avoid damaging oxide or nitride layers under the TERA film and to provide good selectivity.

    摘要: A method of etching an organic antireflective film layer underlying a patterned resist layer on a semiconductor substrate by contacting the exposed organic film with a fluorocarbon and nitrogen etchant in the presence of a plasma-generated energy and removing exposed areas of the organic film with the etchant. An oxide layer underlying the organic film layer is substantially undamaged after contact with the etchant. The plasma is a high density plasma and preferably contains argon, C4F8, and nitrogen.

    摘要: By providing a photoresist material with a protective polymer layer during the etching of an organic anti-reflective coating, undue damage to the photoresist material can be avoided during opening of the anti-reflective coating without the need for an oxidant. The preferred polymer chemistry system for producing such a result includes a fluorohydrocarbon-containing polymer mixture with a strong source of CF3, preferably C2F6. The etchant also includes a source of hydrogen selected from CH3F, C2HF5, or CH2F2, and a diluent selected from Ar, He or N2.
