Publication number: 20240266215Abstract: A method of forming a structure on a substrate, includes forming a nucleation layer within an opening of the substrate within a processing chamber. The method further includes forming a passivation layer on at least a portion of the nucleation layer by introducing radical treatment into the processing chamber. The method further includes forming a tungsten fill layer within the opening over the passivation layer and the nucleation layer, wherein the tungsten fill layer is formed by a plurality of treatment cycles. Each treatment cycle includes pulsing a first gas at the substrate for a pulse time duration while concurrently flowing a second gas over the substrate, and purging the first gas and the second gas by flowing a purge gas over the substrate for a purge time duration.Type: ApplicationFiled: February 8, 2023Publication date: August 8, 2024Inventors: Xi CEN, Yang LI, Kai WU, Mehran BEHDJAT, Jallepally RAVI

Patent number: 10763141Abstract: Embodiments of the disclosure relate to methods for measuring temperature and a tool for calibrating temperature control of a substrate support in a processing chamber without contact with a surface of the substrate support. In one embodiment, a test fixture with a temperature sensor is removably mounted to an upper surface of a chamber body of the processing chamber such that the temperature sensor has a field of view including an area of the substrate support that is adjacent to a resistive coil disposed in the substrate support. One or more calibration temperature measurements of the area of the substrate support are taken by the temperature sensor and simultaneously one or more calibration resistance measurements of the resistive coil are taken corresponding to each calibration temperature measurement. Temperature control of a heating element disposed in the substrate support is calibrated based on the calibration temperature and calibration resistance measurements.Type: GrantFiled: March 17, 2017Date of Patent: September 1, 2020Assignee: APPLIED MATERIALS, INC.Inventors: Niraj Merchant, Lara Hawrylchak, Mehran Behdjat, Dietrich Gage, Christopher Dao, Binh Nguyen, Michael P.

Patent number: 10665476Abstract: In one aspect, a valve assembly adapted to seal an opening in a chamber is disclosed. Valve assembly includes a housing being adapted for coupling to a chamber surface having the opening therein, the housing including a threshold portion positioned adjacent to the chamber opening, the threshold portion having one or more inlets adapted to supply gas to an interior region of the housing adjacent to the chamber opening; and a sealing surface adapted to selectively (1) seal the opening, and (2) retract from the opening so as not to obstruct substrate passage. Numerous other system aspects are provided, as are methods and computer program products in accordance with these and other aspects.Type: GrantFiled: July 18, 2014Date of Patent: May 26, 2020Assignee: Applied Materials, Inc.Inventors: Efrain Quiles, Mehran Behdjat, Robert B.

Patent number: 10453718Abstract: Embodiments disclosed herein generally relate to a slit valve door assembly for sealing an opening in a chamber. A slit valve door that is pressed against the chamber to seal the slit valve opening moves with the chamber as the slit valve opening shrinks so that an o-ring pressed between the slit valve door and the chamber may move with the slit valve door and the chamber. Thus, less rubbing of the o-ring against the chamber may occur. With less rubbing, fewer particles may be generated and the o-ring lifetime may be extended. With a longer lifetime for the o-ring, substrate throughput may be increased.Type: GrantFiled: September 24, 2013Date of Patent: October 22, 2019Assignee: APPLIED MATERIALS, INC.Inventors: Mehran Behdjat, Shinichi Kurita, John M. White, Suhail Anwar, Makoto Inagawa
