A pattern exposure apparatus comprising: a rotary drum that supports a flexible substrate, which is exposed with a mask pattern formed on an outer circumferential surface of a cylindrical mask that rotates about a first center axis; a rotary drum-side scale portion that is arranged for measuring a movement of the substrate which is fed in a circumferential direction by a rotation of the rotary drum, that includes a scale; a first projection optical system that projects an exposure light; a second projection optical system that projects an exposure light; a first reading device that is arranged to oppose with the rotary drum-side scale portion and that reads the scale; and a second reading device that is arranged to oppose with the rotary drum-side scale portion and that reads the scale.

A super-resolution system for nano-patterning is disclosed, comprising an exposure head that enables a super-resolution patterning exposures. The super-resolution exposures are carried out using electromagnetic radiation and plasmonic structures, and in some embodiments, plasmonic structures having specially designed super-resolution apertures, of which the bow-tie and C-aperture are examples. These apertures create small but bright images in the near-field transmission pattern. A writing head comprising one or more of these apertures is held in close proximity to a medium for patterning. In some embodiments, a data processing system is provided to re-interpret the data to be patterned into a set of modulation signals used to drive the multiple individual channels and multiple exposures.

A pattern forming apparatus comprising: a rotary drum that includes a cylindrical outer circumferential surface which is curved at a predetermined radius from a predetermined center line, that rotates about the center line in a state in which a part of a sheet substrate is supported in a length direction of the sheet substrate along the outer circumferential surface; a pattern forming part that forms the pattern on the sheet substrate at a first specific position; a scale disk that is fixed to an end portion of the rotary drum in a direction in which the center line extends while being coaxial with the center line and that includes a circular scale; and a first reading mechanism that is arranged to oppose with the scale formed at the outer circumferential surface of the scale disk, that is arranged at substantially same azimuth as an azimuth.

A system for constructing a roller-type nanoimprint lithography (RNIL) master comprises a master fabrication tool positioned in relation to a metal sleeve which is axially mounted on a rotatable drum. As part of the manufacturing process, the metal sleeve is applied with a layer of photoresist. Then, a laser writing instrument for the master fabrication tool exposes the photoresist in a defined, controller-regulated pattern using highly-focused pulses of light. Using alignment fiducials on the metal sleeve for registration, the laser writing instrument sensitizes the photoresist in a designated pattern as the rotatable drum continuously moves both rotationally and linearly about its longitudinal axis. In connection with one manufacturing process, the photoresist is sensitized at variable depths by modifying the number, duration and intensity of light pulses emitted. Thereafter, light-sensitized photoresist is removed during a development step, with the remaining photoresist hardened and coated to yield a high-precision feature pattern.

A drawing pattern includes at least one stepped pattern that is drawn at least partially on an inclined surface of a stepped structure and extends in a longitudinal direction in a plan view, and the drawing apparatus includes: a modulator that has a diffraction grating including a plurality of diffractive elements arrayed in an array direction; a rotation mechanism that rotates a substrate in a horizontal plane; and a controller that controls the rotation mechanism to adjust an orientation of the substrate on the horizontal plane such that the longitudinal direction of the at least one stepped pattern substantially coincides with an orthogonal direction orthogonal to the array direction in the plan view.

An extreme ultraviolet lithography system (10) that creates a new pattern (330) having a plurality of densely packed parallel lines (332) on a workpiece (22), the system (10) includes a patterning element (16); an EUV illumination system (12) that directs an extreme ultraviolet beam (13B) at the patterning element (16); a projection optical assembly (18) that directs the extreme ultraviolet beam diffracted off of the patterning element (16) at the workpiece (22) to create a first stripe (364) of generally parallel lines (332) during a first scan (365); and a control system (24). The workpiece (22) includes an existing pattern (233) that is distorted. The control system (24) selectively adjusts a control parameter during the first scan (365) so that the first stripe (364) is distorted to more accurately overlay the portion of existing pattern (233) positioned under the first stripe (364).
