Title: Method and apparatus for inspecting defect in edge of plate material
Inventor: KOIKE SEIJI
IPC: G01N21/88
Filed: 1990-03-15
Abstract: PURPOSE:To detect defects at the edges of a silicon wafer or the like more accurately by comparing and judging a normal signal with an output signal from a photodetector for detecting the scattering light of a beam at the edge part of a body under inspection. CONSTITUTION:A beam 2 generated from a beam generating device 1 is projected on an edge 4 of a silicon wafer 3 to be inspected. Scattering light 5 from the edge 4 is detected with a light detector 6. The output is sent into a discriminating circuit 7. When the edge is normal, the pattern of the scattering light at the edge of the projected light is provided only by the partially reflected light and forms one line locus. Therefore, the output of the detector 6 has the output waveform having one peak at one place. When a crack is present at the edge 4, a plurality of weak line loci appear on the side part of the reflected light in the pattern of the scattering light at the edge. Several small peaks appear at the side part of one large peak in the output waveform of the detector 6. The outputs are inputted into the circuit 7, and the number of the peaks is counted. The result is compared with the normal value and judged. Thus the presence or absence of a defect is judged.

Besides, a waveform 13 is obtained by having mutual relation with the waveform 12, a peak value comes to the center position of the mark, and the signal (p) caused by a defect does not effect the decision of the peak value. As a result, the error in the decision of mark position can be prevented.

Abstract: PURPOSE:To enable to control smooth speed and arbitrary deceleration of a truck by comparing the length from each station to a target station with the length added with a deceleration distance to the maximum distance of the distance between the stations and using the smaller one as remaining distance to be moved. CONSTITUTION:Since the distance to a target position is larger than the sum of the longest distance L2 between stations and the deceleration distance A in the station 1, L2+A is set to the remaining distance counter. Subsequently, the value of the counter decreases upon moving of a truck. Since the distance to the target position is larger than L2+A even in the station 2, L2+A is set to the remaining distance counter. Since the distance L1 to the target position is smaller than L2+A in the station 3, L1 is set to the remaining distance counter. Lphi is set to the remaining distance counter similarly even in the station 4.
