摘要： A cleaning equipment generally comprises: a cleaning bath 30 for storing therein a cleaning solution to allow a semiconductor wafer W to be dipped in the cleaning solution to clean the surface of the wafer W; a cleaning solution supply pipe 33 for connecting the cleaning bath 30 to a pure water supply source 31; a chemical storing container 34 for storing therein a chemical; a chemical supply pipe 36 for connecting the cleaning solution supply pipe 33 to the chemical storing container 34 via an injection shut-off valve 35; and a diaphragm pump 37 for injecting a predetermined amount of chemical from the chemical storing container 34 into pure water flowing through the cleaning solution supply pipe 33. The temperature of the cleaning solution in the cleaning bath 30 is detected by, e.g., a temperature sensor 44. On the basis of a detection signal outputted from the temperature sensor 44, the amount of the chemical injected by the diaphragm pump 37 is controlled so that the concentration of the chemical is a predetermined concentration. Thus, a predetermined amount of chemical can be injected so as to clean the wafer W with a predetermined concentration of chemical.

摘要： Disclosed is a liquid treatment for an object to be processed, such as a semiconductor wafer or a glass LCD substrate, which is designed to remove any chemicals remaining in chemical supply nozzles and also improve the rinse capability and throughput. To that end, a processing liquid supply means is configured as jet nozzle pipes 40, a bottom surface 40c of each of the jet nozzle pipes 40 is inclined so as to slope downward from a chemical supply side thereof to an end portion, and the end portion is connected to a drain pipe 55 by a waste liquid orifice 40d and a drain valve 54. A chemical is supplied from nozzle orifices 40b of the jet nozzle pipes 40, the chemical is brought into contact with wafers W, and a treatment is performed thereby. Thereafter, a chemical-removing agent such as pure water or N.sub.2 is supplied through the jet nozzle pipes 40 to remove any remaining chemical from the jet nozzle pipes 40, then pure water is brought into contact with the wafers W to wash them.

摘要： A cleaning tank 30 stores a cleaning liquid to clean the surfaces of semiconductor wafers W immersed in the cleaning liquid. A cleaning liquid supply pipe 33 connects the cleaning tank 30 to a pure water supply source 31. A chemical liquid container 34 stores a chemical liquid, and a chemical liquid supply pipe 36 connects the cleaning liquid supply pipe 33 to the chemical liquid container 34 via an infusion open/close switching valve 35, and a chemical liquid feed means is interposed in the chemical liquid supply pipe 36. The chemical liquid feed means is a reciprocal pump, such as diaphragm pump 37. Thus, a predetermined quantity of the chemical liquid can be infused into pure water or to a drying gas generator to ensure that the chemical liquid of a predetermined concentration be available for washing or drying treatment, regardless of fluctuations in flow amount or pressure of pure water or a drying gas carrier gas.
