A state detection device includes at least one chuck pin for holding a substrate, a photographing unit configured to photograph the chuck pin, and set at least one image to be obtained as a target image, a matching coordinate calculation unit configured to perform matching processing between the target image and a reference image which is at least one image showing the chuck pin, and calculate matching coordinates, which are coordinates indicating a position of the reference image in the target image when a matching score between the reference image and the target image is the highest, and a detection unit configured to detect an open/closed state of the chuck pin based on the matching coordinates. Therefore, the open/closed state of the chuck pin can be detected while detection accuracy is suppressed from lowering.

A machine and a wafer processing apparatus are provided; the machine includes a body and an adjustment part. The body is configured to bear a wafer; the adjustment part is disposed in the body, and the adjustment part uses a vacuum suction to adjust a levelness of an in-process wafer.

Embodiments disclosed herein generally relate to a system and, more specifically, a substrate processing system. The substrate processing system includes one or more cooling systems. The cooling systems are configured to lower and/or control the temperature of a body of the substrate processing system. The cooling systems include features to cool the body disposed in the substrate processing system using gas and/or liquid cooling systems.

An electrostatic chuck device includes: an electrostatic chuck plate having a dielectric substrate having a placement surface on which a wafer is placed and an adsorption electrode positioned in the dielectric substrate; a metal base supporting the electrostatic chuck plate from a back surface side opposite to the placement surface; and a focus ring installed on an outer peripheral portion of the electrostatic chuck plate and surrounding the placement surface. The electrostatic chuck plate has a ring adsorption region which is adsorbed to the focus ring and is located on a surface positioned on the same side as the placement surface and has a base adsorption region which is adsorbed to the metal base and located on a back surface opposite to the placement surface.

A substrate processing system includes a vacuum transfer module; a plasma process module; a transfer robot in the vacuum transfer module; a stage in the plasma process module; a first ring disposed on the stage and a second ring disposed on the first ring to surround a substrate that is placed on the stage, the second ring having an inner diameter smaller than an inner diameter of the first ring; actuators to move support pins vertically to raise the first and the second rings and a transfer jig; and a controller configured to selectively execute a simultaneous transfer mode in which the transfer robot is caused to simultaneously transfer the first ring and the second ring and a sole transfer mode in which the transfer robot is caused to transfer only the second ring.

Methods and systems for performing sample lift-out and protective cap placement for highly reactive materials within charged particle microscopy systems are disclosed herein. Methods include preparing a nesting void in a support structure, translating at least a portion of a sample into the nesting void, and milling material from a region of the support structure that defines the nesting void. The material from the region of the support structure is milled such that at least some of the removed material redeposits to form an attachment bond between the sample and a remaining portion of the support structure. In various embodiments, the sample can then be investigated using one or more of serial sectioning tomography on the sample, enhanced insertable backscatter detector (CBS) analysis on the sample, and electron backscatter diffraction (EBSD) analysis on the sample.

Methods and systems for creating attachments between a sample manipulator and a sample within a charged particle systems are disclosed herein. Methods include translating a sample manipulator so that it is proximate to a sample, and milling portions of the sample manipulator such that portions are removed. The portion of the sample manipulator proximate to the sample is composed of a high sputter yield material, and the high sputter yield material may be the material milled with the charged particle beam such that it is removed from the sample manipulator. According to the present disclosure, the portions of the sample manipulator are milled such that at least some of the removed high sputter yield material redeposits to form an attachment between the sample manipulator and the sample.

Provided is a substrate support unit including an electrostatic chuck configured to fix a wafer, an insulating isolation unit, which is arranged below the electrostatic chuck and is configured to insulate the electrostatic chuck, and a ground plate arranged below the insulating isolation unit, wherein the electrostatic chuck, the insulating isolation unit, and the ground plate are spaced apart from each other in a vertical direction, and a lower surface of the electrostatic chuck, a surface of the insulating isolation unit, or a surface of the ground plate has hydrophobicity.
