Publication number: 20110036809Abstract: A method of forming a microchannel as well as a thin film structure including same is made by forming a first thin film on a side of a substrate, forming a fugitive second thin film on the first thin film such that the second thin film defines a precursor of the elongated microchannel and a plurality of extensions connected to and extending transversely relative to the precursor along a length thereof A third thin film is formed on the first thin film and the fugitive second thin film such that the second thin film resides between the first thin film and the third thin film. A respective access site is formed in a region of the third thin film residing on a respective extension and penetrating to the fugitive second thin film. The fugitive second thin film forming the precursor is selectively removed from between the first thin film and the third thin film using an etching medium introduced through the access sites, thereby forming the microchannel between the first thin film and the third thin film.Type: ApplicationFiled: July 1, 2010Publication date: February 17, 2011Inventors: Horacio D.

Publication number: 20110024387Abstract: An easy and high-efficient tip probe manufacturing method is provided. The manufacturing method of a tip type probe having a metal film on side surfaces of a truncated pyramid formed of a top surface and the side surfaces includes the steps of: forming an etching mask of a shape similar to a shape of the top surface on a substrate; forming the truncated pyramid by subjecting the substrate to isotropic etching using the etching mask as a mask member; stopping the isotropic etching after an area of the top surface becomes smaller than an area of the etching mask; and forming the metal film by allowing film forming particles to round about and enter into a space between the etching mask and the side surfaces.Type: ApplicationFiled: February 18, 2009Publication date: February 3, 2011Inventor: Majung Park

Publication number: 20110024390Abstract: The invention provides an improved apparatus and method for removing oxidized and embedded scale from sheet metal by high pressure spraying a diluted hydrochloric acid water mixture onto the surface of the sheet metal. The contaminated water/acid solution is then re-circulated to remove ferrous chloride from the acid and water solution. The cleansed acid and water solution are recycled for reuse. The sheet metal is rinsed with hot water, dried, oiled and rolled. The rinse water is re-circulated to remove acid droplets and the acid droplets are recycled to an acid storage tank. Any contaminants removed from the rinse water are recycled to a combination filter and reverse osmosis system. The clean rinse water is reused to rinse further sheet metal.Type: ApplicationFiled: July 28, 2009Publication date: February 3, 2011Inventors: Gene Hubbard, Robert Glenn Meeks

Publication number: 20110010950Abstract: A novel application of the atomic layer deposition (ALD) process for producing a conformal coating on a razor blade is disclosed where a uniform, conformal, dense coating is deposited on an entire surface of a blade flank and at least a portion or an entire surface of a blade body. To improve the shaving ability of the coated blade edge (e.g., decrease the blade tip radius), the ALD-produced coating may be etched during, after, or both during and after, the ALD process.Type: ApplicationFiled: July 17, 2009Publication date: January 20, 2011Inventors: John Madeira, Neville Sonnenberg

Publication number: 20110006799Abstract: A prescribed pattern is formed on a thin metal plate by photolithography. The thin metal plate is etched by using the pattern as a mask to form a plurality of through-holes having diameters greater than diameters of probes, in the thin metal plate. The etching is performed on a plurality of the thin metal plates. After the pattern is removed, the plurality of thin metal plates are laminated by conforming the through-holes of each of the thin metal plates to guide pins of a guide. The laminated plurality of thin metal plates are bonded by diffusion bonding. An insulating film is formed on surfaces of the thin metal plates and an inner surface of each of the through-holes. A film thickness of the insulating film is adjusted so that inner diameters of the through-holes whereupon the insulating film is formed match with the diameters of the probes.Type: ApplicationFiled: February 17, 2009Publication date: January 13, 2011Applicant: TOKYO ELECTRON LIMITEDInventors: Jun Mochizuki, Shinichiro Takase
