Patent number: 8444775Abstract: Shape Memory Alloy tube is protected from damage during drawing, caused by galling-type interaction between the tube and high-carbon dies, by forming an oxide surface layer. This invention protects the tube internal diameter from oxidation while allowing the tube outside diameter to be oxidized, by using an oxygen getter located within the tube during the oxidation step. The method yields a higher quality internal diameter and improves productivity.Type: GrantFiled: September 26, 2008Date of Patent: May 21, 2013Assignee: Johnson Matthey Public Limited CompanyInventors: Edwin Alfred Crombie, III, William Andrew Hochella

Publication number: 20120287494Abstract: A metal layer is formed on a highly light-transmissive substrate; a resist mask having an opening pattern is formed on the metal layer; exposed portions of the metal layer is etched away in this state to form openings; then the resist mask is removed; and a surface of the metal layer and an inner side wall of each of the openings are oxidized to form a metal oxide layer. Thus, a front surface and a rear surface of the aperture plate are caused to have different reflectances. The oxide layer is formed at the same time as when the resist mask is ashed to remove resist.Type: ApplicationFiled: March 26, 2012Publication date: November 15, 2012Inventors: Kouhei Takahashi, Takeshi Kuriyagawa, Daisuke Sonoda, Takuo Kaitoh, Katsumi Matsumoto

Publication number: 20120282483Abstract: A method is provided which includes forming a metal layer and converting at least a portion of the metal layer to a hydrated metal oxide layer. Another method is provided which includes selectively depositing a dielectric layer upon another dielectric layer and selectively depositing a metal layer adjacent to the dielectric layer. Consequently, a microelectronic topography is formed which includes a metal feature and an adjacent dielectric portion comprising lower and upper layers of hydrophilic and hydrophobic material, respectively. A topography including a metal feature having a single layer with at least four elements lining a lower surface and sidewalls of the metal feature is also provided herein. The fluid/s used to form such a single layer may be analyzed by test equipment configured to measure the concentration of all four elements. In some cases, the composition of the fluid/s may be adjusted based upon the analysis.Type: ApplicationFiled: July 2, 2012Publication date: November 8, 2012Applicant: LAM RESEARCH CORPORATIONInventors: Igor C.
