Publication number: 20220406582Abstract: An apparatus has a keeper plate with a keeper plate outer perimeter. An annular magnet array with an annular magnet array outer perimeter is coincident with the keeper plater outer perimeter. An inner top magnet is positioned on a centerline of a first side of the keeper plate and an inner bottom magnet is positioned on the centerline of a second side of the keeper plate. The inner top magnet is of a first magnetic orientation and the annular magnet array and the inner bottom magnet have a second magnetic orientation opposite the first magnetic orientation to form a magnetic field environment that provides plasma confinement of ionizing electrons which causes a gas operative as a reactive gas and sputter gas to become ionized and subsequently be directed to a target cathode while simultaneously causing the ionization of sputtered species which are dispersed across a substrate.Type: ApplicationFiled: August 24, 2022Publication date: December 22, 2022Inventors: Samuel D.

Publication number: 20210355579Abstract: A method for forming thin film layer having micro-voids therein. The method proceeds by dispersing micro-particles over the surface of a substrate. The micro particles are made of sublimable material. Then the thin film layer is formed over the surface, so as to cover the particles. The thin film is then etched back so as to expose the particles at least partially. The material of the particles is then sublimed, e.g., by heating the substrate, thereby leaving micro-voids inside the thin film layer. The micro voids can be filled or remain exposed to generate textured surface.Type: ApplicationFiled: May 3, 2021Publication date: November 18, 2021Inventors: Terry Bluck, Samuel D. Harkness, IV

Patent number: 9896758Abstract: A physical vapor deposition (PVD) chamber for depositing a transparent and clear hydrogenated carbon, e.g., hydrogenated diamond-like carbon, film. A chamber body is configured for maintaining vacuum condition therein, the chamber body having an aperture on its sidewall. A plasma cage having an orifice is attached to the sidewall, such that the orifice overlaps the aperture. Two sputtering targets are situated on cathodes inside the plasma cage and are oriented opposite each other and configured to sustain plasma there-between and confined inside the plasma cage. The plasma inside the cage sputters material from the targets, which then passes through the orifice and aperture and lands on the substrate. The substrate is moved continuously in a pass-by fashion during the process.Type: GrantFiled: February 14, 2017Date of Patent: February 20, 2018Assignee: INTEVAC, INC.Inventors: David Fang Wei Chen, David Ward Brown, Charles Liu, Samuel D.

Publication number: 20140102888Abstract: A deposition system is provided, where conductive targets of similar composition are situated opposing each other. The system is aligned parallel with a substrate, which is located outside the resulting plasma that is largely confined between the two cathodes. A “plasma cage” is formed wherein the carbon atoms collide with accelerating electrons and get highly ionized. The electrons are trapped inside the plasma cage, while the ionized carbon atoms are deposited on the surface of the substrate. Since the electrons are confined to the plasma cage, no substrate damage or heating occurs. Additionally, argon atoms, which are used to ignite and sustain the plasma and to sputter carbon atoms from the target, do not reach the substrate, so as to avoid damaging the substrate.Type: ApplicationFiled: October 4, 2013Publication date: April 17, 2014Applicant: Intevac, Inc.Inventors: Samuel D.
