Abstract: PROBLEM TO BE SOLVED: To provide a circuit pattern testing apparatus which facilitates convenient and rapid creation of a recipe, comparison and display of images, setting of test regions, or other operations. SOLUTION: In the circuit pattern testing apparatus 1, when performing a test, with a created recipe applied to a plurality of wafers, the recipe is copied from one shelf number to another shelf number on a graphic screen display of a cassette wherein the wafers are held. A defect information file from another testing apparatus is retrieved, and based on the content of the file, a new recipe for the circuit pattern testing apparatus 1 is created. Moreover, from the results of merging of test results or overlapping of dies and shots, areas which require no test are assigned using graphics on the screen to create new test areas or change the test areas.

Abstract: A semiconductor wafer inspection tool and a semiconductor wafer inspection method capable of conducting an inspection under appropriate conditions in any one of an NVC (Negative Voltage Contrast) mode and a PVC (Positive Voltage Contrast) mode is provided. Primary electrons 2 are irradiated onto a wafer to be inspected 6 and the irradiation position thereof is scanned in an XY direction. Secondary electrons (or reflected electrons) 10 from the wafer to be inspected 6 are controlled by a charge control electrode 5 and detected by a sensor 11. An image processor converts a detection signal from the sensor 11 to a detected image, compares the detected image with a predetermined reference image, judges defects, an overall control section 14 selects inspection conditions from recipe information for each wafer to be inspected 6 and sets a voltage to be applied to the charge control electrode 5. A Z stage 8 sets the distance between the wafer to be inspected 6 and the charge control electrode 5 according to this voltage.
