Abstract:
A method for transferring a pattern from a mask to a substrate (or wafer), comprises dividing a mask generation data file into a plurality of segments. The segments include a main pattern area and a stitching area. Each stitching area contains a respective common pattern. An image of an illuminated portion of the main pattern area is formed. Connection ends of the segments in a substrate area (or wafer area) are illuminated with an illumination beam. An image of the illuminated portion of the main pattern area is formed, and a halftone gray level dosage distribution is produced in the substrate area (or wafer area) corresponding to the common pattern. The common patterns of adjacent segments substantially overlap in the substrate area (or wafer area).

Abstract:
A touch device to sense and compute the coordinate of a touch object is provided. The touch device comprises a panel, a light-emitting element, an image sensor, a reflective strip and a processing unit. The panel has a sensing area surrounded by first to fourth boundaries where the first and the third boundaries define an x direction and the other two boundaries defines y direction. The light-emitting element and the image sensor are located on the first boundary with a specific distance therebetween. The reflective strip is located on the second to fourth boundaries. When the touch object touches the sensing area, a first and a second light path from the light-emitting element to the image sensor are blocked to form a real and a virtual image such that the processing unit computes the coordinate of the touch object according to the real and the virtual images. A touch method is disclosed herein as well.
Abstract:
A handheld electronic device and an operating method thereof are provided. The handheld electronic device includes a first body, a second body, and a moving assembly. The moving assembly includes a sliding module and at least one rotating module. The sliding module is coupled to the second body, wherein the second body is moveable between a first position and a second position. The rotating module is coupled between the first body and the sliding module so that the second body is rotated relative to the first body. The second body is automatically rotated from the second position to a third position to form a first angle with the first body. The second body can be rotated between the third position and a fourth position to form a second angle with the first body, wherein the second angle is greater than the first angle.
