Proximity exposure method
A proximity exposure method, wherein a mask (M) of which the master patterns (31) are formed larger than the resolution limit of the resist (R) is prepared with respect to the resist patterns (43) having the minimum pitch (P) equal to or smaller than the resolution limit of the resist (R); in the first exposure step, the mask (M) and the workpiece (W) are relatively step-moved by the pitch (P) of the resist patterns (43) after the mask patterns (31) are exposed and transferred onto the workpiece (W); and in the second exposure step, the mask patterns (31) are exposed and transferred onto the workpiece (W) again.
Imprint apparatus
The present invention provides an imprint apparatus that performs imprint processing of forming a pattern of an imprint material on a substrate using a mold, the apparatus including an image sensing unit configured to sense at least one of the mold and the substrate and obtain an image, and a determination unit configured to determine normality/abnormality of the imprint processing, wherein the imprint processing includes a first step of supplying the imprint material onto the substrate, and a second step of bringing the mold and the imprint material on the substrate into contact with each other, and the determination unit changes a reference of determination of the normality/abnormality of the imprint processing for each step of the imprint processing and determines the normality/abnormality of the imprint processing based on the image sensed by the image sensing unit.
Position detector, position detection method, imprint apparatus, and product manufacturing method
A position detector includes a detection unit configured to detect light from a first diffraction grating including a first pattern disposed in a first direction, and light from a second diffraction grating including a second pattern disposed in the first direction, and a control unit configured to obtain a relative position between the first and the second diffraction gratings based on the light detected by the detection unit. The position detector has a third pattern formed in a second direction different from the first direction at edges of the first pattern of the first diffraction grating, the third pattern has a width smaller than a width of the first pattern of the first diffraction grating.
Dual-layer alignment device and method
A dual-layer alignment apparatus is disclosed which includes: a fixed frame (40) and, disposed thereon, a first measuring device (50) and a mark plate (41), the mark plate (41) having a fixed-frame mark (20); and a motion stage (60) and, disposed thereon, a reference mark (30), a motion-stage mark (70) and a second measuring device (10). The first measuring device (50) is configured to measure a relative positional relationship between the reference mark (30) and the motion-stage mark (70), the second measuring device (10) is configured to measure a relative positional relationship between the reference mark (30) and the fixed-frame mark (20), from which a final relative positional relationship between the motion-stage mark (70) and the fixed-frame mark (20) is derived, based on which the motion stage (60) is displaced to a target location. A corresponding dual-layer alignment method is also disclosed. In the apparatus, the motion stage (60) is the only movable component. Additionally, coordinate relationships can be calibrated in a static manner in order to immunize calibration accuracy from positioning accuracy of the motion stage (60), such that the alignment accuracy is improved. Further, a dual- or multi-lens design can be employed to allow additional improvements in flexibility and alignment efficiency.
PROXIMITY EXPOSURE METHOD
A proximity exposure method, wherein a mask (M) of which the master patterns (31) are formed larger than the resolution limit of the resist (R) is prepared with respect to the resist patterns (43) having the minimum pitch (P) equal to or smaller than the resolution limit of the resist (R); in the first exposure step, the mask (M) and the workpiece (W) are relatively step-moved by the pitch (P) of the resist patterns (43) after the mask patterns (31) are exposed and transferred onto the workpiece (W); and in the second exposure step, the mask patterns (31) are exposed and transferred onto the workpiece (W) again.
