Patent number: 12183558Abstract: An apparatus for combining plasma processing and thermal processing of a workpiece is presented. The apparatus includes a processing chamber, a plasma chamber separated from the processing chamber disposed on a first side of the processing chamber, and a plasma source configured to generate a plasma in the plasma chamber. A quartz workpiece support is disposed within the processing chamber, the workpiece support configured to support a workpiece. One or more radiative heat sources configured to heat the workpiece are disposed on a second and opposite side of the first side of the processing chamber. A dielectric window is disposed between the workpiece support and the one or more heat sources. In addition, the apparatus includes a temperature measurement system configured to obtain a temperature measurement indicative of a temperature of the workpiece.Type: GrantFiled: October 25, 2023Date of Patent: December 31, 2024Assignees: Beijing E-Town Semiconductor Technology Co., Ltd., Mattson Technology, Inc.Inventors: Dixit Desai, Alex Wansidler, Dieter Hezler, Joseph Cibere, Rolf Bremensdorfer, Pete Lembesis, Michael Yang
