Title: Wafer-positioning mechanism of surface inspection device
Inventor: NAKADAI TSUTOMU
IPC: H01L21/66
Filed: 1987-07-24
Abstract: PURPOSE:To position wafers of different outer diameters by a method wherein distances from the pivot center of two or more pivot arms to a contact point or a wafer contact face of a wafer contact material are equal and these arms are turned in an identical direction by an identical amount while these arms are interlinked. CONSTITUTION:Individual pivot arms 4 are turned toward the center of a rotary table 2 while they are interlinked; distances from individual axes 4b as the pivot center of the individual pivot arms 4 to a contact face with individual rollers 4a are equal. The center of a circle formed by the individual pivot arms 4 arranged in a circular form coincides with the center of the rotary table 2. When the pivot arms 4 are turned, a wafer is positioned in the center of the rotary table 2. During this process, if an outer diameter of the wafer is large, the pivot arms 4 are turned until they come into contact with a periphery of the wafer; after that, a roller 10a turns a grooved sheet cam 9 to the outside; no further turning force is exerted on the pivot arms 4. By this setup, an actuator is actuated during a shifting process up to an inspection position of a wafer mounting mechanism 1; the grooved cam 9 advances or retreats; the wafer is positioned in such a way that it coincides with the center of the rotary table 2.
