Abstract: PURPOSE:To increase the speed of feedback by composing the title inspection device of a long-sized light source for oblique projection light tying line focuses in the direction rectangular to the direction of carrying of a wafer surface, a projection lens, a long-sized receiving lens receiving only irregular reflected light, a receptor, and a douser mutually making oblique projection light, irregular reflected light and reflected light independent. CONSTITUTION:Linear oblique projection light L emitted from a light source 10 is focussed on the surface of a wafer 1 placed onto a carrier 6 jagging in the direction (a) as line beams by a projection lens 11. When there is no dust and foreign matter on the surface of the wafer 1, oblique projection light L total-reflects on the surface of the wafer 1 and is changed into reflected light L', and the light is recognized as normal reflected light. When contaminated particles adhere on the surface of the wafer 1, oblique projection light L is turned into scattered light and one part thereof is converted into irregular reflected light L'' and condensed to a receptor 13 through a receiving lens 12, and an electric signal is generated from the receptor 13. The electric signal is fed back to a preprocess as an alarm, and the wafer is treated as an abnormal one while a countermeasure treatment is executed in the preprocess, and subsequent wafers are changed into nondefectives. Accordingly, the status of the adhesion of contaminated particles on all wafers is monitored, thus improving the yield of the wafers.

IPC: A61B6/00
Filed: 1984-10-29
Abstract: PURPOSE:To improve sensitivity by shortening the inside of a radiation stop piece near the boundary of adjacent parts of collimators by specific length. CONSTITUTION:A ring type collimator 2 is so constituted that the stop piece 31 is made short at end parts of respectively parallel collimators 3 and a blind sector part 4 formed near the boundary where the parallel collimators 3 adjacent to each other is made small; the sensitivity of the whole system is improved and the visual field 5 is made large as long as the internal diameter of a ring type radiation detector 1 is equal.
