Assignee: ASM IP HOLDING B.V.
Field: Surface technology, coating (Chemistry)
Classification: CPC C  H | IPC C  H

Claim 5:
6. The substrate processing device of claim 1, wherein the substrate supporting unit is configured to:
support the substrate to be processed through the contact surface of the first protrusion during a first operation of the substrate processing device, and
support the substrate to be processed through both of the contact surface of the first protrusion and the upper surface of the second protrusion during a second operation of the substrate processing device,
wherein active species are formed when an electric power is supplied between a gas supply unit and the substrate supporting unit, and
wherein the second protrusion is configured to relocate the active species adjacent to the second protrusion such that the active species are arranged around a center of the substrate to be processed,
wherein the substrate processing device further comprises a suction force generator generating a suction force,
wherein, when the substrate to be processed is deformed due to the suction force, the deformed substrate is in line contact with the first protrusion and at the same time in contact with the second protrusion so that the line contact of the substrate by the first protrusion is maintained to prevent flow of reactive gas into the backside of the substrate to be processed and the second protrusion supports the substrate to be processed during the deformation.
