Abstract:
A substrate feed chamber comprising:a substrate holding tray storage device capable of storing simultaneously three or more substrate holding trays that hold substrates in a vertical or substantially vertical condition; a horizontal movement mechanism that produces horizontal movement of said substrate holding tray storage device; and a rotary movement mechanism that rotates said substrate holding tray storage device about an axis perpendicular to the plane of the horizontal movement of said horizontal movement mechanism; wherein said horizontal movement mechanism effects horizontal movement of said substrate holding tray storage device with respect to the substrate feed position for performing feeding-in or feeding-out movement of said substrate holding tray between any of the chambers of a group of chambers consisting of one or more substrate processing chambers where a given processing is performed on said substrates and one or more load lock chambers where feeding in/out of said substrates between atmospheric atmosphere and vacuum atmosphere is performed.
