Abstract

A high-pressure processing apparatus for removing unnecessary matters on objects to be processed by bringing a high-pressure fluid and a chemical liquid other than the high-pressure fluid into contact with the objects to be processed in a pressurized state is provided with a plurality of high-pressure processing chambers, a common high-pressure fluid supply unit for supplying the high-pressure fluid to each one of the high-pressure processing chambers, a common chemical liquid supply unit for supplying the chemical liquid to the each high-pressure processing chambers, and a separating unit for separating gaseous components from a mixture of the high-pressure fluid and the chemical liquid discharged from the high-pressure processing chambers after the objects are processed.Thus, a high-pressure processing apparatus which has such a compact construction as to be partly installable in a clean room and can stably perform a high-pressure processing can be provided.
