Title: Method for inspecting micro-scratch and device therefor using the same
Inventor: JUN CHUNG-SAM
IPC: G01N21/21
Filed: 2000-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a micro-scratch inspection method by which defects, such as scratches etc., on the surface of a wafer can be detected effectively by quickly discriminating the defects at a high recognition rate and a micro-scratch inspection device using the method. SOLUTION: In a micro-scratch inspection method, a wafer to be inspected is scanned by making light obliquely incident on the medium layer of the wafer at a prescribed angle. The light is made incident within an extent in which the reflection of the light from the underlying layer the medium layer can be suppressed and reflected light is converted into electric signals by eliminating scattered light as much as possible. After position-wise electric intensity signals on the surface of a wafer are obtained from the electric signals, defects are detected by comparing the signals with each other.  When this method is used, micro-scratches formed on the surface of the wafer can be monitored successively and defects including the micro-scratches, etc., formed on the surface of the medium layer can be inspected regardless of the underlying structure of the medium layer, particularly, a pattern layer.

IPC: B23Q17/09
Filed: 2000-08-31
Abstract: PROBLEM TO BE SOLVED: To provide an automatic lathe capable of reducing idle time by reducing the time required for detecting whether or not a cutting tool has been broken. SOLUTION: If a workpiece W is cut by a cut-off tool 5a, a feed lever 12 is rotated to a second rotating position, so that an abutting member 28 moves from a detection standby position to a detecting position without abutting against the end of the workpiece W. This movement of the abutting member 28 to the detecting position brings a detection element 29 into engagement with a detecting portion 30a to turn a detecting switch 30 on. If the workpiece W is not cut by the-cut-off tool 5a, the feed lever 12 is rotated to a second rotating position, so that the workpiece W is left behind and restricts the movement of the abutting member 28, with the abutting member abutting against the end of the workpiece W.  Upon restriction of the movement of the abutting member 28, movement of the abutting member 28 to a detecting position is avoided and the detecting element 29 is not engaged with the detecting part 30a and the detecting switch 30 is maintained in its off state.
