Title: Visual inspection apparatus of wafer
Inventor: KOMATSU ATSUSHI
IPC: H01L21/66
Filed: 1991-04-17
Abstract: PURPOSE:To increase the inspection speed of the title apparatus without overlooking that a foreign body has adhered by a method wherein, when the title wafer is judged to be abnormal at a comparison judgment, a dark-field lens is inserted in an optical path at the posterior stage of an object lens. CONSTITUTION:An object lens 3a whose magnification is comparatively low is provided; an absorption pattern region on a wafer 4 is expanded. Whether an abnormality exists or not in the pattern region is judged by a pattern matching operation. When the region is judged to be abnormal, a changeover part 11 actuates a changeover mechanism 12 by the instrcution of a computer 8, and a dark-field lens 10 is arranged in an opetical path. A first image and a second image are displayed on a display 9. At this time, a foreign body can more easily be detected because the image of a foreign body 13 having the size of A can be seen as the size of B as the image of scattered light. When an object lens whose magnification is lower than that of conventional object lenses, its angle of field can be expanded in inverse proportion to its magnification. As a result, a region to be inspected per wafer is reduced, and an inspection operation can be shortened.

Filed: 1983-05-17
Abstract: PURPOSE:To obtain the correlation value of an astable signal with a small error and a short interval approximately equal to a sampling cycle, by cascading the integration units consisting of shift registers having different numbers of delay stages and accumulation address. CONSTITUTION:A digital signal x(t) which is sampled in a cycle T supplied from an input terminal 1 is branched into two parts. One of these two branched signals is supplied directly to a multiplier 5; and the other signal is supplied to the multiplier 5 after receiving a delay of time D from a delay shift register 4. Thus x(t)Xx(t-D) is obtained and supplied to an integration unit 20. If (n) units of integration sections are provided in terms of the sample number, the number of stages of a shift register 21 is set at (n). Then the n-unit preceding input is delivered to an adder 16. This adder 16 functions as a subtractor. The outputs of the adder 16 are cumulatively added by an adder 17 and a register 8, and an integration output is obtained at an output terminal 3. Then integration units 20' of different number of stages of the register 21 are cascaded to obtain an integrator, and the correlation value is extracted from an output terminal 3' of the integrator.
