摘要： A scan control unit for generating two-dimensional coordinates for performing a scan with an electron beam of an electron scanning microscope is provided with first and second transforming units for transforming coordinates in the horizontal (X) direction and the vertical (V) direction. An area to be tested in a sample is scanned with an electron beam in an arbitrary direction. As the first and second transforming units, small-capacity transformation tables (LUTs) capable of operating at high speed in each of the horizontal (X) direction and the vertical (Y) direction are used. By also using a large-capacity transformation table (LUT) that stores coordinate transformation data corresponding to plural scan types, a test apparatus compatible with the plural scan types, having multiple functions, and capable of performing high-speed scan control is realized.

摘要： Disclosed is a semiconductor wafer testing apparatus that resolves the following problems which arise when semiconductor wafers become larger: (1) complexity of stage acceleration/deceleration control; (2) throughput reduction; and (3) increased vibration of the stage support platform during the stage inversion operation (deterioration in resolution). In the semiconductor wafer testing apparatus for resolving these problems, a wafer is rotated, an electro beam is irradiated onto the rotating wafer from a scanning electron microscope, and secondary electrons emitted from the wafer are detected. The detected secondary electrons are A/D converted by an image processing unit, realigned by an image data realignment unit, and then image-processed for display. As a result, image information of all dies of a wafer can be acquired without a large amount of movement of the stage in the X and the Y directions.

摘要： A signature circuit, i.e., a random-number generating circuit, is provided in a memory test apparatus. Also, a signature circuit is provided in each of devices-under-test. This configuration allows the large number of semiconductor integrated-circuit devices to be tested at one time with a high efficiency. This condition realizes a tremendous reduction in the test cost.
