摘要： A semiconductor wafer 11 is irradiated for scanning with a charged particle beam 6 so as to detect secondary charged particles 9 obtained from the wafer 11 as a result of the irradiation of the beam 6. A detected image of an inspection area obtained based on scanning information and on a detection signal derived from the secondary charged particles 9 is compared with a detected image of a reference area to find a difference therebetween. The difference is compared with a threshold value to detect a defect candidate. Defect information including positional information about the defect candidate is generated in such a manner as to include a relative position of a predetermined feature point within each of repeat patterns formed on the semiconductor wafer 11 with regard to the origin of a coordinate area established in each of these repeat patterns, and a relative position of the defect candidate with regard to the feature point. This contributes to providing a defect inspecting apparatus capable of determining defective areas for extraction by FIB more easily than before.

摘要： High-speed inspection is performed with appropriate sensitivity according to the pattern density and pattern characteristic of a device.The pixel dimension used in image acquisition is changed in accordance with the pattern density of a device. An image is acquired at high speed by changing the beam scan speed and the stage drive speed in accordance with the pixel dimension and eliminating an error by controlling the amount of beam delay. The acquired image is so resampled that the image dimensions of the acquired image and a reference image are equally sized, and the acquired image and the reference image are then aligned with each other. The aligned images are resampled in accordance with a preset pixel dimension to extract a difference between the images with the sensitivity according to the pixel dimension.

摘要： Provided is a circuit-pattern inspection device which enables efficient inspection of a semiconductor wafer by selectively inspecting areas on the semiconductor wafer, such as boundaries between patterns thereon, where defects are likely to occur during the step of producing the semiconductor wafer while changing the beam scanning direction for each area. Two-dimensional beam-deflection control is employed for inspection operations in a continuous-stage-movement-type circuit-pattern inspection device in which only one-dimensional scanning has been employed conventionally. That is, by employing a combination of an electron-beam-deflection control in a first direction parallel to the stage-movement direction and an electron-beam-deflection control in a second direction intersecting the stage-movement direction, it is possible to obtain an image of any desired area for inspection that is set within a swath. The amplitude of deflection signals for the electron-beam-deflection and the rise and fall timings of the signals are suitably controlled according to inspection conditions.

摘要： Since charging characteristics differ between the outer circumferential portion and the center portion of a sample to be inspected, equivalent inspection sensitivities cannot be obtained in the outer circumferential portion and the center portion of the sample to be inspected. A sample cover is provided in the outer circumferential portion of a sample holder on which the sample to be inspected is placed. Charging characteristics of the sample cover are changed according to charging characteristics of the sample to be inspected. Consequently, uniform charged states can be formed in the outer circumferential portion and the center portion of the sample. Inspection/observation of the outer circumferential portion of the sample can be realized at higher sensitivity than in the past.
