In an embodiment, a sealing medium is provided between each of the plurality of first concentric separators, and the second concentric separators are inserted into a surface of the sealing medium.

A deposition apparatus includes an electrostatic chuck which supports a substrate, a mask assembly disposed on a surface of the substrate, a deposition module disposed to be movable in a horizontal direction intersecting a thickness direction of the mask assembly, where the deposition module discharges a deposition material to the mask assembly, and a camera which captures an image of the electrostatic chuck or the mask assembly, where the deposition module is in a deposition position overlapping the mask assembly in the thickness direction of the mask assembly while the deposition module discharges the deposition material, and is in a standby position not overlapping the mask assembly in the thickness direction of the mask assembly while the deposition module does not discharge the deposition material, and the camera captures the image of the electrostatic chuck or the mask assembly when the deposition module is in the standby position.

A plasma processing system is provided. The system comprises a plasma processing apparatus, a transfer apparatus connected to the plasma processing apparatus, and a controler. The plasma processing apparatus includes a substrate support including a support unit for a substrate as well as an annular member disposed to surround the substrate. The substrate support includes a plurality of insertion holes passing through the support unit, lifters to elevate/lower the annular member through the holes insertion and a temperature adjustment mechanism for adjusting a temperature of the support unit. The transfer apparatus includes a transfer mechanism for transferring the annular member to the substrate support. The annual member has includes concave portions in its bottom surface, into which upper end the lifters are fitted.

A cleaning method according to one aspect of the present disclosure which cleans an electrostatic chuck includes exposing the electrostatic chuck to plasma and maintaining a relationship between a potential of the electrostatic chuck and a potential of the plasma such that electron current is introduced from the plasma toward the electrostatic chuck.

A pick-up structure for a memory device and method for manufacturing memory device are provided. The pick-up structure includes a substrate and a plurality of pick-up electrode strips. The substrate has a memory cell region and a peripheral pick-up region adjacent thereto. The pick-up electrode strips are parallel to a first direction and arranged on the substrate in a second direction. The second direction is different from the first direction. Each pick-up electrode strip includes a main part in the peripheral pick-up region and an extension part extending from the main part to the memory cell region. The main part is defined by fork-shaped patterns of a first mask layer. The extension part has a width less than that of the main part, and the extension part has a side wall surface aligned with a side wall surface of the main part.

A ceramic joined body includes: a pair of ceramic plates; and an electrode layer that is interposed between the pair of ceramic plates, in which the electrode layer is embedded in at least one of the pair of ceramic plates, and in an outer edge of the electrode layer, a joint surface between the at least one of the pair of ceramic plates and the electrode layer has an inclination with respect to a thickness direction of the pair of ceramic plates and the electrode layer.

A pressure control system includes a first sensor, a second sensor, an evacuation valve and a controller. The first sensor is configured to detect a frontside pressure within a processing chamber. The frontside pressure is indicative of a downforce on a substrate disposed on a substrate support within the processing chamber. The second sensor is configured to detect a backside pressure on a backside of the substrate. The controller is configured to: control the evacuation valve to remove gas from and reduce the frontside pressure of the processing chamber; and during the removal of gas from a reduction in the frontside pressure of the processing chamber and based on the frontside pressure and the backside pressure, regulate an opening of the evacuation valve such that the frontside pressure does not drop below the backside pressure.
