Patent number: 8546263Abstract: Embodiments of the invention generally relate to methods for fabricating devices on semiconductor substrates. More specifically, embodiments of the invention relate to methods of patterning magnetic materials. Certain embodiments described herein use a reducing chemistry containing a hydrogen gas or hydrogen containing gas with an optional dilution gas at temperatures ranging from 20 to 300 degrees Celsius at a substrate bias less than 1,000 DC voltage to reduce the amount of sputtering and redeposition. Exemplary hydrogen containing gases which may be used with the embodiments described herein include NH3, H2, CH4, C2H4, SiH4, and H2S. It has been found that patterning a magnetic tunnel junction with an oxidizer-free gas mixture comprising hydrogen maintains the integrity of the magnetic tunnel junction without producing harmful conductive residue.Type: GrantFiled: April 27, 2011Date of Patent: October 1, 2013Assignee: Applied Materials, Inc.Inventors: Olivier Joubert, Benjamin Schwarz, Jérémy Gilbert Maurice Pereira, Kevin Menguelti, Erwine Maude Pargon, Maxime Darnon

The inventive composition comprises a TiOx(OH)y(H2O)z(x+y?+z=3) titanium oxide-based polymer in the form of a gel or sol. Said polymer, which has a one-dimensional (1D) structure, is made from concentrically-wound fibers having a periodicity which is deduced from the spacing between said fibers, of between 3.5 ? and 4 ?. Each fiber comprises TiO6octahedrons and each TiO6octahedron shares two opposite edges with two adjacent octahedrons (2.times.2.92 ?) in order to form infinite chains which develop along the axis of a fiber. According to the invention, two adjacent chains form double lines as a result of the shared edges (2.times.3.27 ?).

Publication number: 20010012592Abstract: A process for patterning a feature on a substrate using a plasma polymerized methylsilane (PPMS) photoresist layer or similar organosilicon film. The process includes the step of depositing a PPMS film having upper and lower strata such that the upper stratum is more photosensitive to ultraviolet radiation than is the lower stratum. In one embodiment, the upper and lower strata are formed in a multistep deposition process that, preferably, takes place in a single deposition chamber. In another embodiment, the upper and lower strata are formed by a process in which deposition parameters are modified to deposit a PPMS layer having a photosensitivity gradient between the upper and lower strata. In still another embodiment, various intermediate strata are formed. Preferably, each intermediate stratum has a photosensitivity that is higher than the stratum directly beneath it.Type: ApplicationFiled: March 15, 2001Publication date: August 9, 2001Applicant: Applied Materials, Inc.Inventors: Olivier Joubert, Cedric Monget, Timothy Weidman, Dian Sugiarto, David Mui
