Patent number: 12217994Abstract: An electrostatic chuck device containing a substrate, a stack stacked on an upper surface of the substrate in the thickness direction, and a ceramic layer stacked on an upper surface of the stack in the thickness direction. A sleeve formed from an insulating material is inserted into a through-hole that penetrates through the substrate and the stack in the thickness direction. The upper surface of the sleeve in the thickness direction has a two-level structure including a first upper surface positioned on the same plane as an upper surface of the substrate in the thickness direction, and a second upper surface positioned above the first upper surface in the thickness direction of the sleeve and disposed proximate to the ceramic layer. In a plan view, an edge portion of the stack is disposed on top of the first upper surface.Type: GrantFiled: March 5, 2021Date of Patent: February 4, 2025Assignee: TOMOEGAWA CORPORATIONInventor: Nobuyoshi Yamazaki

Patent number: 12176237Abstract: An electrostatic chuck device is provided in which the occurrence of cracking in a ceramic layer, the cracking being caused by a difference in thermal expansion between a substrate and a sleeve due to heat generated during formation of the ceramic layer, is suppressed. The electrostatic chuck device includes a substrate, a laminated body that is laminated on the substrate and that includes at least an internal electrode, and a ceramic layer that is laminated on the upper surface of the laminated body in the thickness direction. The electrostatic chuck device is such that the substrate has a through-hole provided so as to pass through in the thickness direction, a sleeve formed from an insulating material is inserted into the through-hole, and the sleeve is joined to the through-hole via a joining means at an upper portion of the substrate in the thickness direction.Type: GrantFiled: February 10, 2021Date of Patent: December 24, 2024Assignee: TOMOEGAWA CORPORATIONInventors: Tomoya Hagihara, Jun Tochihira
