To fully remove particles and build-up in a load lock chamber.
The load lock chamber 2 is airtightly connected to a separation chamber 3 airtightly connected to treatment chambers 11, 12 and 13 where a substrate 9 is specifically treated inside, and a transport mechanism carries the substrate 9 between the atmosphere side and the treatment chambers 11, 12, and 13 via the load lock chamber 2 and the separation chamber 3. The load lock chamber 2 has size and weight so that a human can hold in hands, and at the same time accommodates only a sheet substrate 9, and no transport mechanism is present within the load lock chamber 3. The load lock chamber 2 is connected so that it can be completely separated from the separation chamber 3, and an inner wall surface is cleaned by washing liquid after the separation.
