DEVICES AND METHODS FOR HIGH ANGLE LIQUID ELECTRON TOMOGRAPY
Devices and methods are described for performing high angle tilting tomography on samples in a liquid medium using transmission electron beam instruments.
Sample loading method and charged particle beam apparatus
Provided is a sample loading method of loading a cooled sample into a sample exchange chamber of a charged particle beam apparatus includes: attaching the sample container in which a sample and liquid nitrogen are accommodated to the sample exchange chamber via a gate valve; evacuating a space between a liquid surface of the liquid nitrogen and the gate valve in a state in which the gate valve is closed; discharging the liquid nitrogen in the sample container after the space between the liquid surface of the liquid nitrogen and the gate valve has been evacuated; evacuating a space in the sample container after the liquid nitrogen in the sample container has been discharged; and opening the gate valve after the space in the sample container has been evacuated.
PLASMA PROCESSING DEVICE AND RETRACTABLE SEALING PART THEREOF
Disclosed are a plasma processing device and a retractable sealing part thereof. The retractable sealing part is arranged in or near a radio-frequency circuit of the plasma processing device. The retractable sealing part includes a bellows assembly having a first end and a second end. Isolation rings are added to an upper part and a lower part of the bellows assembly to weaken longitudinal radio-frequency coupling. Metal sleeves are added to an inner side and an outer side of the bellows assembly to shield transverse radio-frequency coupling. The present disclosure effectively shields radio-frequency coupling on the basis of maintaining the functions of vacuum isolation and extension and retraction of the retractable sealing part, thereby obtaining the stable radio-frequency circuit and etching rate.
Charged particle beam system
Provided is a charged particle beam system capable of reducing the force applied to a sample when a chuck device grips the sample. The charged particle beam system is typified by an electron microscope including a sample chamber, a sample exchange chamber connected to the sample chamber, a sample container capable of being removably attached in the sample exchange chamber, and a transport device for transporting the sample between the sample container and the sample exchange chamber. The transport device includes the chuck device for gripping the sample, a drive mechanism for moving the chuck device in a given direction, a mechanical driver for actuating the chuck device, and a power transmission mechanism for transmitting power of the mechanical driver to the chuck device. The power transmission mechanism includes a shaft and a resilient member that elastically deforms when a force in the given direction is applied to the shaft.
REPLACEABLE MODULE FOR A CHARGED PARTICLE APPARATUS
Disclosed herein is a module for supporting a device configured to manipulate charged particle paths in a charged particle apparatus, the module comprising: a support arrangement configured to support the device, wherein the device is configured to manipulate a charged particle path within the charged particle apparatus; and a support positioning system configured to move the support arrangement within the module; wherein the module is arranged to be field replaceable in the charged particle apparatus.
Sample Cartridge Carrier Apparatus and Carrier Base
A sample cartridge carrier apparatus is coupled with a focused ion beam processing apparatus (FIB processing apparatus). A guide mechanism is configured to guide a series of movements of a sample cartridge holder to allow a sample cartridge to be held by a carrier base on a sub stage. Sub cooling equipment is configured to cool the sample cartridge via the sub stage. A carrier mechanism carries the carrier base between the sub stage and a main stage.
Linear Motor for Vacuum and Vacuum Processing Apparatus
A vacuum processing apparatus includes a linear motor. The linear motor includes a mover having a permanent magnet, a stator having a coil covered by a resin member, and a wire for supplying a current to the coil provided in a vacuum sample chamber. The wire is led out to an outside of the vacuum sample chamber through a through hole portion provided in the wall surface of the vacuum sample chamber. The through hole portion is filled with the resin member integrally or with a filler that binds to the resin member, so that the through hole portion is sealed.
Sample Stage
Sample stage, e.g. for use in a scanning electron microscope. The sample stage includes a base, a sample carrier, and an actuator assembly arranged for moving the sample carrier in at least one direction substantially parallel to the base. The actuator assembly is arranged so as not to contribute to the mechanical stiffness of the sample stage from the sample carrier to the base.
SAMPLE COLLECTION DEVICE AND MANUFACTURING METHOD THEREOF
A sample collection device includes two substrates and a spacer. The two substrates are disposed oppositely. Each substrate has a first surface, a second surface opposing to the first surface, a first recess and at least one second recess. The two substrates are arranged with the first surfaces facing each other, and the first and second recesses are respectively located on each first surface. The first recesses of the substrates jointly form a first channel, and the second recesses of the substrates jointly form a second channel connected to the outside of the sample collection device. The first channel and the second channel are interconnected. The spacer is disposed between the two first surfaces for bonding and fixing the two substrates. A sample containing space is formed between the two substrates and the spacer. The sample containing space includes the first chancel and the second channel. In addition, a manufacturing method of the sample collection device is also provided.
VACUUM PROCESSING APPARATUS AND METHOD FOR CONTROLLING VACUUM PROCESSING APPARATUS
The present disclosure relates to a vacuum processing apparatus. The vacuum processing apparatus includes a processing container capable of maintaining an inside thereof in a vacuum atmosphere, a stage provided in the processing container and on which a substrate is placed, a support member passing through an opening formed at a bottom of the processing container to support the stage from below, a holder part located outside the processing container, a flange part arranged around the opening on the outside of the processing container, and a sealing part configured to be expandable and contractible and provided inside the spherical bearing along the circumferential direction of the opening so as to airtightly seal at least a space between the flange part and the holder part.
