Title: Method for inspecting foreign matter on lattice face plate
Inventor: HONDA MASASHI
IPC: H01L21/66
Filed: 1990-08-10
Abstract: PURPOSE:To make it possible to perform inspection efficiently by providing a dark-field light receiving system for detecting scattered light and a bright-field light receiving system for detecting the change in direction of regular reflection, and obtaining the detected data of a foreign matter. CONSTITUTION:When a laser spot is cast on a lattice face palte 1a, the scat tered light from a foreign matter is received with a photoelectric converter 6-1 of a dark-field light receiving system, and a received photocurrent I1 is outputted. However, the change in direction of the regular reflected light from the foreign matter is very weak. The light is not received with a bright-field light receiving system. A constant received photocurrent I2 is outputted from a photoelectric converter 6-2. The direction of the regular reflected light from the protruding surface of the edge of a lattice groove 1b is changed, and the light is received witha photoelectric converter 6-3. A received photocurrent I3 is outputted. Therefore, the detected data of the edge of the lattice groove 1b are erased by subtracting the associated data stored in a memory, and only the detected data of the foreign matter attached to the lattice face plate 1a are obtained.
