    摘要: A method of manufacturing an IC that comprises fabricating a semiconductor device. Fabricating the device includes depositing a photoresist layer on a substrate surface and implanting one or more dopant species through openings in the photoresist layer into the substrate, and, into the photoresist layer, thereby forming an implanted photoresist layer. Fabricating the device also includes removing the implanted photoresist layer. Removing the implanted photoresist layer includes exposing the implanted photoresist layer to a mixture that includes sulfuric acid, hydrogen peroxide and ozone. The mixture is at a temperature of at least about 130°.

    摘要: A method of removing photoresist from a surface during the manufacture of an integrated circuit. Organometallic polymers and monomers are formed during the etch of a hard mask material defining the locations of a metal-bearing film, such as tantalum nitride, when photoresist is used to mask the hard mask etch. These organometallic polymers and monomers as formed are not fully cross-linked. A liquid phase solution of sulfuric acid and hydrogen peroxide used to remove the photoresist also removes these not-fully-cross-linked organometallic polymers and monomers, thus preventing the formation of stubborn contaminants during subsequent high temperature processing.

    摘要: A method of fabricating metal-bearing structures in an integrated circuit such as metal-polysilicon capacitors using conductive metal compounds. Defects due to organometallic polymers formed during the etch of a hard mask material are minimized by using a process that includes a plasma etch for the hard mask that achieves a predominantly chemical character using a fluorine-based etch chemistry. Using a low-temperature liquid-phase strip of the hard mask photoresist instead of an ash prevents further cross-linking of polymers formed during the plasma etch. Etching the metal-bearing material using a hot fully-concentrated mixture of ammonium hydroxide and hydrogen peroxide allows short etch times that are particularly shortened for tantalum nitride films deposited with a nitrogen concentration of about 30 percent or greater.
