Patent ID: 10861730

Abstract:
An object is to provide an electrostatic chuck device having high heat resistance, which can be used even under high-temperature environment. An electrostatic chuck device includes: an electrostatic chuck section having a placing surface for placing a plate-shaped sample on one main surface thereof and an electrode for electrostatic adsorption; a temperature-controlling base section which is provided on the other side of the electrostatic chuck section in relation to the placing surface to cool the electrostatic chuck section; a heater element which is provided in a form of a layer between the electrostatic chuck section and the temperature-controlling base section; and a first adhesive layer which is provided between the heater element and the electrostatic chuck section to adhere the heater element and the electrostatic chuck section to each other, in which the first adhesive layer is made of inorganic glass or an inorganic material having a partially crystallized glass structure.
