Abstract:

A method for fabricating a magnetic recording transducer having a magnetic writer pole with a short effective throat height is provided. In an embodiment, a writer structure comprising a magnetic writer pole having a trailing bevel and a nonmagnetic stack on the top surface of the writer pole is provided. A dielectric write gap layer comprising alumina is deposited over the trailing bevel section and the nonmagnetic stack; and at least one etch stop layer is deposited over the dielectric write gap layer. A layer of nonmagnetic fill material is deposited over the etch stop layer and to form a nonmagnetic bevel by performing a dry etch process. The etch stop layer(s) are removed from the short throat section; and a trailing shield is deposited over the short throat section, nonmagnetic bevel, and nonmagnetic stack top surface.

US Classification:

430319

Abstract:

A method for fabricating a magnetic transducer having a nonmagnetic intermediate layer is described. A pole is provided on the intermediate layer. The pole has sides, a bottom, a top wider than the bottom and a leading bevel proximate to an ABS location. A side gap is provided adjacent to at least the sides of the pole. A bottom antireflective coating (BARC) layer is provided on the intermediate layer. The BARC layer is removable using a wet etchant and is adjacent to at least a portion of the side gap. A mask layer is provided on the BARC layer. A pattern is photolithographically transferred into the mask layer, forming a shield mask. Part of the BARC layer is exposed to the wet etchant such that the sides of the pole and the side gap are free of the BARC layer. At least a magnetic side shield is provided.

US Classification:

435 72

Abstract:

This invention relates to peptide ligand discovery and is particularly directed to a method for the discovery of agonists for membrane bound receptors. The inventive detection system involves the use of a "tethered" ligand for probing receptor binding. The general detection system includes a membrane, a membrane bound receptor, and a chimeric ligand presenting molecule. This chimeric protein forms the tethered ligand and in turn includes a membrane domain, a linker domain, a ligand domain, and a cleavable terminal domain. The "ligands" of the system are exposed by the addition of a specific peptidase that cleaves at the designated sequence. The sequence of the ligand that produces signal as a result of the interaction between the agonist and receptor can be then be isolated using sib selection.

Abstract:

Methods for the rapid detection of the presence or absence of Hepatitis B Virus (HBV) in a biological or non-biological sample are described.
