In one embodiment, a charged particle beam drawing apparatus performs drawing by deflecting a charged particle beam with a deflector. A method for evaluating the apparatus includes making a shot of a first pattern, controlling a deflection amount by the deflector to move an applied position of the beam from the first pattern along a first direction to make a shot of a second pattern, controlling the deflection amount to move the applied position from the second pattern along the first direction to make a shot of a third pattern, controlling the deflection amount to move the applied position from the third pattern along a second direction opposite to the first direction to make a shot of a fourth pattern between the second pattern and the third pattern, calculating an interval between the second pattern and the fourth pattern, and comparing the calculated interval to a reference interval.

The present invention relates to an electron beam (eBeam) resist composition, particularly an (eBeam) resist composition for use in the fabrication of integrated circuits. Such resist compositions include an anti-scattering compound which minimises scattering and secondary electron generation, thus affording extremely high resolution lithography. Such high resolution lithography may be used directly upon silicon-based substrates to produce integrated circuits, or may alternatively be used to produce a lithographic mask (e.g. photomask) to facilitate high-resolution lithography.

According to one embodiment, a pattern formation method includes placing an imprint resist film on a substrate, then imprinting a pattern in the imprint resist film. The pattern has a first loop section in a first end portion and a second loop section in a second end portion. After the imprint resist film has been patterned, it is selectively irradiated between the first loop section and the second loop section. The imprint resist film is then etched under conditions leaving the selectively irradiated portion of the imprint resist film and removing the unirradiated portion of the imprint resist film.

A charged particle beam drawing device includes: a storage unit that stores a pattern generation program for generating pattern data, the pattern generation program being a program in which an instruction for specifying a type of a figure and an instruction for specifying a regular arrangement of the figure are described; an execution unit that executes the pattern generation program stored in the storage unit; and a control unit that performs drawing control based on the pattern data generated by the executed pattern generation program.

According to one embodiment, a proximity effect correcting method includes acquiring drawing information for drawing a pattern on a substrate with irradiation of an electron beam. The method further includes acquiring surface profile information related to a surface profile of the substrate. The method further includes calculating an energy distribution of a backscattered beam to be produced by backscattering of the electron beam in the substrate on a basis of the acquired drawing information and surface profile information. The method further includes calculating a required energy amount of the electron beam on a basis of the calculated energy distribution.

Systems, devices, and methods for performing a non-contact electrical measurement (NCEM) on a NCEM-enabled cell included in a NCEM-enabled cell vehicle may be configured to perform NCEMs while the NCEM-enabled cell vehicle is moving. The movement may be due to vibrations in the system and/or movement of a movable stage on which the NCEM-enabled cell vehicle is positioned. Position information for an electron beam column producing the electron beam performing the NCEMs and/or for the moving stage may be used to align the electron beam with targets on the NCEM-enabled cell vehicle while it is moving.

Provided is a focused ion beam processing apparatus including: an ion source; a sample stage a condenser lens; an aperture having a slit in a straight line shape; a projection lens and the sample stage, wherein, in a transfer mode, by Köhler illumination, with an applied voltage of the condenser lens when a focused ion beam is focused on a main surface of the projection lens scaled to be 100, the applied voltage is set to be less than 100 and greater than or equal to 80; a position of the aperture is set such that the focused ion beam is masked by the aperture with the one side of the aperture at a distance greater than 0 μm and equal to or less than 500 μm from a center of the focused ion beam; and the shape of the slit is transferred onto the sample.

An e-beam apparatus is disclosed, the tool comprising an electron optics system configured to project an e-beam onto an object, an object table to hold the object, and a positioning device configured to move the object table relative to the electron optics system. The positioning device comprises a short stroke stage configured to move the object table relative to the electron optics system and a long stroke stage configured to move the short stroke stage relative to the electron optics system. The e-beam apparatus further comprises a magnetic shield to shield the electron optics system from a magnetic disturbance generated by the positioning device. The magnetic shield may be arranged between the positioning device and the electron optics system.
