Abstract:
1. A vacuum processing apparatus comprising: a process chamber connecting to a vacuum pump; a transporter, which is provided in the process chamber, to transport a plurality of substrates; a gas supply unit, which is provided on the same side as respective surfaces to be processed of the substrates, the gas supply unit having at least one flow control valve to supply process gas to process the substrates in the process chamber; a target holder configured to support a target opposing the substrates, wherein the gas supply unit supplies the process gas to the substrates from a side of the target facing toward the surfaces of the substrates, and a detection sensor configured to detect a substrate interval between adjacent substrates out of the plurality of substrates; and a control device having a controller configured to control, based on the substrate interval detected by the detection sensor, the at least flow control valve and a supply amount of the process gas to be supplied by the gas supply unit.
