Publication number: 20110226611Abstract: A process for modifying a surface of a substrate is provided that includes supplying electrons to an electrically isolated anode electrode of a closed drift ion source. The anode electrode has an anode electrode charge bias that is positive while other components of the closed drift ion source are electrically grounded or support an electrical float voltage.

Publication number: 20110014778Abstract: A coating process to infill high aspect-ratio vias and trenches in semiconductor substrates with dense boron for the production of neutron detectors and other devices uses a vacuum cathodic arc or other source of fully ionized boron plasma. Biasing of the substrate is used to impart energies to the plasma ions directing them toward the substrate, while repulsing the electrons. The full ionization produced by the source allows control of the energies of the boron ions by means of the bias voltage. The bias is alternated between coating deposition at low ion energies and sputtering of already coated material by energetic ions. Most of the sputtered material comes off the substrate top surface and between the trenches or vias and much of it is redeposited, thereby contributing to the infill. The process is suitable for carbon, boron or similar light elements, and is of particular interest for 10B, an element having exceptionally high thermal neutron cross-section.Type: ApplicationFiled: July 20, 2009Publication date: January 20, 2011Inventors: C.

Publication number: 20100276272Abstract: A hard bias (HB) structure for longitudinally biasing a free layer in a MR sensor is disclosed that includes a mildly etched seed layer and a hard bias (HB) layer on the etched seed layer. The HB layer may contain one or more HB sub-layers stacked on a lower sub-layer which contacts the etched seed layer. Each HB sub-layer is mildly etched before depositing another HB sub-layer thereon. The etch may be performed in an IBD chamber and creates a higher concentration of nucleation sites on the etched surface thereby promoting a smaller HB average grain size than would be realized with no etch treatments. A smaller HB average grain size is responsible for increasing Hcr in a CoPt HB layer to as high as 2500 to 3000 Oe. Higher Hcr is achieved without changing the seed layer or HB material and without changing the thickness of the aforementioned layers.Type: ApplicationFiled: May 1, 2009Publication date: November 4, 2010Inventors: Min Zheng, Kunliang Zhang, Min Li

Publication number: 20100258431Abstract: A method and apparatus for manufacturing magnetic storage media is provided. A structural substrate is coated with a magnetically susceptible material, and a patterned resist layer is formed over the magnetically susceptible material. Atom groups are directed toward the substrate, penetrating the resist and implanting into the magnetically susceptible layer. Thick portions of the resist prevent implantation in some areas to form a pattern of magnetic properties on the substrate. Energy and composition of the atom groups, thickness and hardness of the resist, and lattice energy of the magnetically susceptible material may all be adjusted to yield desired fragmentation and implantation of the atom groups, including in some embodiments mere impact on the surface without implanting. A protective layer and a lubricating layer are formed over the patterned magnetically susceptible layer.Type: ApplicationFiled: April 8, 2010Publication date: October 14, 2010Applicant: APPLIED MATERIALS, INC.Inventors: Stephen Moffatt, Majeed A.

Publication number: 20100163422Abstract: A method for forming a magnetic write head using a damascene process that does not form voids in the magnetic structure. An opening is formed in an alumina layer, the opening being configured to define a trench. Then a first layer of magnetic material is deposited into the trench. A CMP process is then performed to remove any voids that have formed in the first magnetic layer. Then a second layer of magnetic material is deposited over the first layer of magnetic material. In another embodiment of the invention, a opening is formed in the alumina layer, and a first layer of magnetic material is electroplated into the opening. A thin layer of non-magnetic material is then deposited, and a second layer of magnetic material is deposited over the thin layer of non-magnetic material. The thin layer of alumina advantageously provides a laminate structure that avoids data erasure.Type: ApplicationFiled: December 30, 2008Publication date: July 1, 2010Inventors: Wen-Chien David Hsiao, Yinshi Liu, Yi Zheng
