Title: Device for outside visible defect inspection
Inventor: HASE SHINOBU
IPC: H01L21/66
Filed: 1983-08-12
Abstract: PURPOSE:To prevent the fluctuation of output value of the intensity of diffracted light generated due to the difference in arrangement direction of the same pattern when a defect detection is performed by a method wherein the direction of polarization of the beam to be made to irradiate on the surface of a pattern is brought into a circular polarization. CONSTITUTION:When a linear polarized plane wave is made to incident on the single axis crystal such as crystal, mica and the like, it is propagated in the form wherein the plane wave is divided into an ordinary light and an abnormal light which oscillate in vertical direction with each other in crystal, and a phase difference is generated due to the difference in refracted index for each light when a crystal plate is injected. At this time, wave length is set up, and when the thickness of the crystal plate is controlled, a 1/4 wave length plate having the phase difference of (2m+1)Xpi/2 (m=0,1...) can be formed. If a linear polarized wave of light is made to incident at an arbitrary angle on the optic axis of the 1/4 wave length plate, an elliptical polarized light can be obtained. However, a circular polarized light is obtained when a linear polarized light is made to incident at 45 deg. on the optic axis. By utilizing the characteristics of said 1/4 wavelength plate and by arranging said wavelength plate at the point located in the midway of the linear polarized beam, a circular polarized beam is formed on a sample 5. When the beam is made to irradiate on the linear edge, the output value is always turned to constant and the fluctuation of output can be suppressed even when there is directivity in the same pattern.
