Patent number: 11224099Abstract: A mineral insulated heating cable for a heat tracing system. The heating cable includes a sheath having at least a first, and optionally a second layer, wherein the thermal conductivity of the second layer is greater than a thermal conductivity of the first layer. In addition, the first and second layers are in intimate thermal contact. The heating cable also includes at least one heating conductor for generating heat and a dielectric layer located within the sheath for electrically insulating the heating conductor, wherein the sheath, heating conductor and dielectric layer form a heating section. In addition, the heating cable includes a conduit for receiving the heating section. Further, the heating cable includes a cold lead section and a hot-cold joint for connecting the heating and cold lead sections. In addition, a high emissivity coating may be formed on the first layer.Type: GrantFiled: September 11, 2018Date of Patent: January 11, 2022Assignee: nVent Services GmbHInventors: Paul Becker, Fuhua Ling, Ningli Liu, Lawrence Joseph White, Louis Peter Martin, II, Scott Murray Finlayson, James Francis Beres, Marcus Kleinehanding

Patent number: 10692703Abstract: Embodiments of the present disclosure generally relate to a substrate support assembly in a semiconductor processing chamber. The semiconductor processing chamber may be a PECVD chamber including a substrate support assembly having a substrate support and a stem coupled to the substrate support. An RF electrode is embedded in the substrate support and a rod is coupled to the RF electrode. The rod is made of titanium (Ti) or of nickel (Ni) coated with gold (Au), silver (Ag), aluminum (Al), or copper (Cu). The rod made of Ti or of Ni coated with Au, Ag, Al or Cu has a reduced electrical resistivity and increased skin depth, which minimizes heat generation as RF current travels through the rod.Type: GrantFiled: March 20, 2017Date of Patent: June 23, 2020Assignee: APPLIED MATERIALS, INC.Inventors: Xing Lin, Jianhua Zhou, Ningli Liu, Juan Carlos Rocha-Alvarez

Patent number: 10480074Abstract: Embodiments disclosed herein generally include an apparatus for radical-based deposition of dielectric films. The apparatus includes a processing chamber, a radical source coupled to the processing chamber, a substrate support disposed in the processing chamber, and a dual-channel showerhead disposed between the radical source and the substrate support. The dual-channel showerhead includes a plurality of tubes and an internal volume surrounding the plurality of tubes. The plurality of tubes and the internal volume are surrounded by one or more annular channels embedded in the dual-channel showerhead. The dual-channel showerhead further includes a first inlet connected to the one or more channels and a second inlet connected to the internal volume. The processing chamber may be a PECVD chamber, and the apparatus is capable of performing a cyclic process (alternating radical based CVD and PECVD).Type: GrantFiled: November 27, 2017Date of Patent: November 19, 2019Assignee: APPLIED MATERIALS, INC.Inventors: Jianhua Zhou, Juan Carlos Rocha-Alvarez, Yihong Chen, Abhijit Basu Mallick, Oscar Lopez, Ningli Liu
