TWO LEVEL VACUUM WAFER TRANSFER SYSTEM WITH ROBOTS ON EACH LEVEL

Exemplary semiconductor processing systems may include a first processing chamber and a second processing chamber. Each processing chamber may define a processing region and a transfer region having a slit valve. Each processing chamber may include a substrate support that is vertically translatable between the processing region and the transfer region. Each processing chamber may include a gas delivery assembly disposed above and in alignment with the substrate support. The first processing chamber and the second processing chamber may be at least substantially aligned along a first vertical axis. The systems may include a first transfer chamber coupled with the first processing chamber via the slit valve. The systems may include a second transfer chamber coupled with the second processing chamber via the slit valve. A transfer robot may be disposed within each transfer chamber. The transfer chambers may be at least substantially aligned along a second vertical axis.
