  • Patent number: 9880233
    Abstract: A method and apparatus to determine a parameter of a metal-containing film are provided herein. In some embodiments, a method of determining a parameter of a metal-containing film may include generating a first magnetic field by flowing an alternating current through a coil disposed adjacent to and spaced apart from the metal-containing film, wherein the first magnetic field induces a second magnetic field proximate the metal-containing film; heating the metal-containing film from a first temperature to a second temperature; measuring a response of the first magnetic field to the second magnetic field as the metal-containing film is heated from the first temperature to the second temperature; and correlating the response with a rate of temperature change of the metal-containing film as the metal-containing film is heated from the first temperature to the second temperature to determine a parameter of the metal-containing film.

  • Patent number: 9490154
    Abstract: Methods and systems for alignment of substrate-scale masks are described. The alignment methods presented may improve the uniformity and repeatability of processes which are impacted by the relative lateral position of a substrate-scale mask and a substrate. The methods involve measuring the “overhang” of the substrate at multiple locations around the periphery of the substrate-scale mask. Based on the measurements, the relative position of the substrate relative to the substrate-scale mask is modified by adjustment of the substrate and/or mask position. The adjustment of the relative position is made in one adjustment in embodiments. A feature of hardware and methods involves the capability of making measurements and adjustments while a substrate processing system is fully assembled and possibly under vacuum.
