摘要:
An electron microscope comprising a microscope chamber having a viewing screen positioned within the chamber and mounted for movement to at least a first position away from a beam of electrons or a second position in which electrons passing through an object or specimen are intercepted by the viewing screen to thereby produce an image. A drive motor is coupled to the viewing screen for moving the screen to either the first or the second position.

An exposure system is equipped with: a first row of chambers that are arranged to be adjacent to a C/D provided on a floor surface F on a +X side; a second row of chambers arranged on the −Y side facing the first row of chambers; and a first control rack adjacent to the to the second row of chambers on a −X side and is arranged on the −Y side facing the C/D. Inside at least a part of the plurality of chambers, exposure chambers where exposure is performed are formed and the first control rack distributes utilities supplied from the below the floor surface to the first and the second rows of chambers.
摘要:
A high voltage inspection system that includes a vacuum chamber; electron optics that is configured to direct an electron beam towards an upper surface of a substrate; a substrate support module that comprises a chuck and a housing; wherein the chuck is configured to support a substrate; wherein the housing is configured to surround the substrate without masking the electron beam, when the substrate is positioned on the chuck during a first operational mode of the high voltage inspection system; and wherein the substrate, the chuck and the housing are configured to (a) receive a high voltage bias signal of a high voltage level that exceeds ten thousand volts, and (b) to maintain at substantially the high voltage level during the first operational mode of the high voltage inspection system.
摘要:
Disclosed is a charged particle beam apparatus wherein a partitioning film capable of transmitting a charged particle beam is provided between a charged particle optical system and a sample, said charged particle beam apparatus eliminating a contact between the sample and the partitioning film even in the cases where the sample has recesses and protrusions. On the basis of detection signals or an image generated on the basis of the detection signals, a distance between a sample and a partitioning film is monitored, said detection signals being outputted from a detector that detects secondary charged particles discharged from the sample due to irradiation of a primary charged particle beam.
摘要:
To provide a charged particle radiation apparatus including a soundproof cover that highly realizes both suppression of image defects due to a specific frequency and improvement in quake resistance. A charged particle radiation apparatus including a box-shaped soundproof cover having a plurality of wall surfaces, the soundproof cover including a plurality of columnar bodies forming a frame of the box shape body and a box-shaped acoustic energy absorbing structure provided in a connecting part of the plurality of columnar bodies and attached to support at least the two columnar bodies, is proposed.
