Abstract
A particle control method is provided which can prevent an extremely small quantity of particles descending on a stream of a laminar flow in a clean zone through which the laminar flow flows as in a RABS or isolator device from descending to a specific position or can guide it so as to descend to the specific position by controlling movement of the particles. A particle descent position is separated away from a board surface of the oscillation board by using an acoustic radiation pressure generated by prompting ultrasonic vibration of the oscillation board disposed with a board surface substantially in parallel with a flow direction of the laminar flow.
