Publication number: 20120132966Abstract: Self-assembled polymer technology is used to form at least one ordered nanosized pattern within material that is present in a conductive contact region of a semiconductor structure. The material having the ordered, nanosized pattern is a conductive material of an interconnect structure or semiconductor source and drain diffusion regions of a field effect transistor. The presence of the ordered, nanosized pattern material within the contact region increases the overall area (i.e., interface area) for subsequent contact formation which, in turn, reduces the contact resistance of the structure. The reduction in contact resistance in turn improves the flow of current through the structure. In addition to the above, the inventive methods and structures do not affect the junction capacitance of the structure since the junction area remains unchanged.Type: ApplicationFiled: October 15, 2007Publication date: May 31, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Bruce B.

Publication number: 20120133004Abstract: A method for producing oblique surfaces in a substrate, comprising a formation of recesses on both surfaces of the substrate, until the recesses are so deep that the substrate is perforated by the two recesses. One recess is produced going out from a first main surface in the region of a first surface, and the other recess is produced going out from the second main surface in the region of a second surface, so that the first surface and the second surface do not coincide along a surface normal of the main surfaces of the substrate. Subsequently, flexible diaphragms are attached over the recesses on each of the main surfaces. If a vacuum pressure is then produced inside the recesses, the flexible diaphragms each curve in the direction of the recesses until their surfaces facing the substrate come into contact with one another, generally in the center of the recesses.Type: ApplicationFiled: November 16, 2011Publication date: May 31, 2012Inventor: Stefan Pinter

Publication number: 20120133008Abstract: Provided are a spin-injection element having high spin-injection efficiency, and a magnetic field sensor and a magnetic recording memory employing the element. The element comprises a barrier layer, a magnetic conductive layer, and a spin accumulation portion comprised of non-magnetic conductive material. In the element, a first spin accumulation layer (103) and the barrier layer (102) have respectively a body-centered cubic lattice structure. Due to this, the first spin accumulation layer (103) and the barrier layer (102) come into contact with each other through a boundary face with improved crystalline symmetry. Thereby, lattice matching is improved and scattering of the tunnel electrons in the ?1 band is prevented, resulting in improvement in the spin polarizability. Further, the characteristics of the device employing the spin injection element are improved.Type: ApplicationFiled: August 4, 2010Publication date: May 31, 2012Inventors: Masaki Yamada, Hiromasa Takahashi
