Claim:
A substrate load lock and delivery system affixable to a processing chamber for processing substrates, comprising: a vacuum load lock chamber connectable to said processing chamber through a loading port arranged about a central axis of said load lock chamber; a single rail within said load lock chamber extending along said central axis in an axial direction towards said loading port but vertically below said loading port; a trolley sliding on and solely supported on said rail; a substrate paddle having a first substrate bearing surface, supported on said trolley, and having a first substrate bearing surface cantilevered from said trolley in said axial direction toward said loading port, wherein during an operation of said system said paddle is disposed at least partially beyond an axial end of said rail; a first magnet carried on said trolley; and a second magnet disposed on an opposite side of a vacuum wall of said vacuum load lock chamber from said first magnet and magnetically coupled to said first magnet and adapted to deliver a substrate between said load lock chamber and said processing chamber.
