Substrate laminating apparatus
A substrate laminating apparatus which sticks substrates together in vacuum with high accuracy. The apparatus includes a first chamber into which two substrates are carried; a second chamber in which substrates are stuck together; and a third chamber which delivers a substrate laminate. The pressure level in the first chamber and the third chamber is varied from atmospheric to medium vacuum under control and that in the second chamber is varied from medium vacuum to high vacuum under control. In the second chamber, electrostatic adsorption means which can move up and down picks up an upper substrate and holds it on an upper table.
