    摘要: A method of fabricating a magnetic device is described. A mask removing layer is formed on a layered sensing stack and a hard mask layer is formed on the mask removing layer. A first reactive ion etch is performed with a non-oxygen-based chemistry to define the hard mask layer using an imaged layer formed on the hard mask layer as a mask. A second reactive ion etch is performed with an oxygen-based chemistry to define the mask removing stop layer using the defined hard mask layer as a mask. A third reactive ion etch is performed to define the layered sensing stack using the hard mask layer as a mask. The third reactive ion etch includes an etching chemistry that performs at a lower etching rate on the hard mask layer than on the layered sensing stack.

    摘要: Radiation sensitive elements comprising a thin radiation sensitive layer of an amorphous chalcogenide of arsenic adhering to a substrate are utilized in the production of latent images when exposed to a suitable form of radiation, the latent images being developed by utilizing the inability of radiation exposed arsenic chalcogenide to cause reduction of noble metal salts. Noble metal salts are thus decomposed by arsenic chalcogenide which has not been exposed to radiation to form a direct positive image which can subsequently be intensified by physical development and/or electroless deposition of metal possibly followed by electrolytic deposition of metal. The form of radiation employed is generally visible light and diverse procedures for producing direct positive images are disclosed.
