Title: Measuring method of principal index of refraction of sample
Inventor: SAKAI KIYOKAZU
IPC: G01N21/41
Filed: 1992-04-24
Abstract: PURPOSE:To enable determination of principal index of refraction in directions of three axes by making a sample tiltable between two polarizing plates and by measuring the intensity of a transmitted light with the polarizing plates rotated in relation to the sample. CONSTITUTION:When directions of polarizing plates 5 and 6 are parallel to the principal axis (x) being parallel to a sample surface or when they are parallel to the other principal axis (y), no double refraction occurs and the intensity of a transmitted light of an apparatus at this time is the maximum. When the directions of the polarizing plates 5 and 6 are located at an angle of 45 deg. in between the principal axes (x) and (y), a light enters a sample S is divided into two equal polarized lights, a light oscillating in the direction of the axis (x) and a light oscillating in the direction of the axis (y). Since the two polarized lights are different in the index of refraction, there is a phase difference between them when they are transmitted through the sample S, and the light transmitted through the sample becomes a light of rotary polarization. When the direction of the polarizing plate 6 is located at the angle of 45 deg. to the principal axes, it takes out only a light component oscillating in this direction and makes it enter a light-sensing element 8. When the phase difference between the two polarized lights in the direction of the principal axis is zero, the transmitted light is transmitted through the polarizing plate 6 and the intensity is the maximum. When the phase difference between the polarized lights is pi, the intensity of the transmitted light becomes zero. When the phase difference is found between zero and pi, it so varies as to be a minimum value not being zero, and therefore retardation is determined on the basis of the intensity of the transmitted light.

At this time, the irradiated surface is selected to be the side face of the wafer 7 rather than an element forming surface 8 of the wafer 7. The side face may be of either an orientation flat face 9 or an arcuate face 10, but the face 9 is more preferable for optical reading of the mark.
