Abstract: A hot spot defect detecting method and a hot spot defect detecting system are provided. In the method, hot spots are extracted from a design of a semiconductor product to define a hot spot map comprising hot spot groups, wherein local patterns in a same context of the design yielding a same image content are defined as a same hot spot group. During runtime, defect images obtained by an inspection tool performing hot scans on a wafer manufactured with the design are acquired and the hot spot map is aligned to each defect image to locate the hot spot groups. The hot spot defects in each defect image are detected by dynamically mapping the hot spot groups located in each defect image to a plurality of threshold regions and respectively performing automatic thresholding on pixel values of the hot spots of each hot spot group in the corresponding threshold region.

Abstract: A photograph device is provided. The photograph device includes a body, a lens device mounted on the body, and an illuminating device mounted on the body and surrounding the lens device.

Abstract: An auto focus device and method are provided. The device comprises a beam splitter set; a laser emitting device disposed at a first side of the beam splitter set for providing a laser beam to the beam splitter; a lens set disposed at a second side of the beam splitter set and opposing to the testing subject positioned at a third side of the beam splitter set for refracting a reflected beam from a testing subject for generating a light spot; and a photo detecting device disposed with respect to the lens set for receiving the light spot and generating a driving signal.

Abstract: A device for measuring a lens, comprising a first interferometer having a first optical axis and carried on a first adjustment base, a lens holder for holding the lens having a first surface having a first lens optical axis and a second surface having a second lens optical axis, and a platen having a sliding rail and carrying the first adjustment base and the lens holder thereon, wherein the lens holder is movable on the sliding rail, wherein each of the first adjustment base and the lens holder has a tetra-axis adjustment mechanism through which a relative positional relationship of the first optical axis of the first interferometer and the first lens optical axis of the first surface of the lens is adjustable.

Abstract: A global real-time transmission and control system, which can track the position of the aircraft by up-linking and down-linking the A/V information and can control the A/V devices equipped on the aircraft. The automatic tracking system includes an aircraft A/V transmitting system disposed on the aircraft, an A/V automatic tracking system at ground for the aircraft, and a ground control system. The automatic tracking system is used to receive information from the aircraft A/V transmitting system, and automatically transmit the received information to the ground control system. According to the actual need, the ground control system can actively obtain the A/V information by the video/camera unit through the aircraft A/V transmitting system and the A/V automatic tracking system. Additionally, a salvaging plane is provided to land on the aircraft, which needs a salvage due to an accident or hijacking occurring on the aircraft.
