| description | PURPOSE:To provide the wafer absorbing and holding function and flat surface by using sintered metal for the chuck surface for absorbing substrates. CONSTITUTION:In a chuck case-body 11, a sintered metal plate 10 is used as the substrate absorbing plate 1, and a vacuum suction hole 12 is drilled onto the back surface side. Therefore, a number of gas holes peculiar to the sintered metl body are uniformly formed onto the absorbing plate 1 of the vacuum chuck, and the force for absorbing a loaded wafer as working object from the back surface side is generated. Therefore, the captioned chuck is provided with the strain correcting function for the held wafers, together with the holding fuction for the substrate such as wafers. |
