Abstract:
1. A method of manufacturing a semiconductor device comprising: supplying a liquid chemical from a first nozzle to a semiconductor substrate at a position above a treating bath; transferring the first nozzle to above a nozzle cleaning bath arranged at a position apart from the treating bath after supplying the liquid chemical; removing materials adhered on an outside of said first nozzle by supplying a cleaning liquid from a second nozzle to said materials at a position above the nozzle cleaning bath; washing away the liquid chemical remaining on the semiconductor substrate by supplying water from a third nozzle at a position above the treating bath; and drying the semiconductor substrate at a position above the treating bath, wherein at least one of washing away the liquid chemical or drying the semiconductor substrate is performed while the first nozzle is located above the nozzle cleaning bath.
