Title:
TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/106979
Kind Code:
A1
Abstract:
[Problem] To perform highly uniform treatment within the surface of a substrate by attracting and holding the substrate with high reliability when the substrate is treated in an atmosphere where no plasma is formed. [Solution] The present invention configures a device so as to be provided with: a DC power supply 35 the positive electrode side of which is connected to one of an electrode 32 of an electrostatic chuck 3 and a conductive member 4 and the negative electrode side of which is connected to the other, that applies a voltage across the electrode 32 and the conductive member 4 located at a treatment position in contact with a substrate W in a state where no plasma is formed in a treatment container 11, and that causes an electrostatically attracting force generated thereby to attract and hold the substrate W on a dielectric layer 31 of the electrostatic chuck 3; and a treatment-gas supply part 28 that supplies a treatment gas to the substrate W to treat the substrate W in a state where the substrate W is attracted to and held on the dielectric layer 31.
