Title: Structure of wafer handling chuck
Inventor: WATANABE TETSUYA
IPC: H01L21/68
Filed: 1988-07-29
Abstract: PURPOSE:To ensure sucking action even if a chuck itself is in the horizontal state or in the downward inclined state by inclining the contact surface of a wafer handling chuck at a small downward inclining angle in the direction of the center of a wafer with respect to a horizontal plane. CONSTITUTION:The surface of a chuck is cut and inclined by an angle theta in downward direction toward the center of a wafer, and a new contact surface 4c is formed. The slant angle theta is set at a value which is larger than the maximum value of the upward slant angle that is formed by the movement of the chuck itself. When the chuck 4 itself is in the horizontal state and the chuck is lifted, a part of the contact surface 4c comes contact with the lower surface of the wafer. At this stage, sucking does not occur since there is a gap. When the chuck is further lifted, the wafer is raised with the chuck and inclined with a mounting table 2 as a supporting point. Both surfaces are brought into contact at a position where the slant angle theta' agrees with the slant angle thetaof the contact surface 4c. Therefore there is no gap, and the wafer is sucked with air A.
