    Abstract: Provided is an electrostatic chuck device in which the attachment of particles to the rear surface of a plate-like specimen can be further suppressed by suppressing the generation source of the particles and, furthermore, an effect of cooling the plate-like specimen using a cooling gas can be improved. The electrostatic chuck device is formed by including an electrostatic chuck portion in which an upper surface (2a) of a ceramic plate-like body (2) is used as a placement surface on which a wafer is placed and an electrostatic adsorption electrode is provided inside the ceramic plate-like body (2) or on the rear surface thereof, multiple protrusions (11) are formed on the upper surface (2a), and multiple fine protrusions (13) are formed in regions (12) excluding the multiple protrusions (11) in the upper surface (2a).

    Abstract: An electrostatic chuck apparatus is disclosed which can be prevented from being damaged or fractured when the temperature abruptly increases or decreases when plasma is irradiated on a plate-like specimen, the heater is heated, or the like, and can also prevent corrosion when a corrosive gas or plasma is provided. The electrostatic chuck apparatus has an electrostatic chuck portion 2 having a mounting plate 11 made of a corrosion-resistant ceramic, a supporting plate 12 which is integrated with the mounting plate 11 so as to support the mounting plate 11 and is made of an insulating ceramic having a larger thermal conductivity than the thermal conductivity of the corrosion-resistant ceramic, and an internal electrode for electrostatic adsorption 13 provided between the mounting plate 11 and the supporting plate 12; and a temperature-controlling base portion 3 which adjusts the electrostatic chuck portion 2 to a desired temperature.
