An electrolytic cell for producing acidic water and alkaline water is disclosed. High-purity acidic water and high-purity alkaline water can be produced in a well balanced proportion from ultrapure water which is supplied in the minimum amount necessary for producing the desired acidic and alkaline waters using the minimum amount of electricity. The electrolytic cell includes an electrolytic acidic-water production unit 3 comprising an anode chamber 6 and an auxiliary cathode chamber 7 separated therefrom by a first ion-exchange membrane 5, and an electrolytic alkaline-water production unit 4 comprising a cathode chamber 10 and an auxiliary anode chamber 9 separated therefrom by a second ion-exchange membrane 8. Separately controllable power supplies are also provided for supplying power to each of the two units. The supply amount of pure water and the amount of electricity used can be fixed according to the desired amounts of acidic and alkaline waters. Thus, wasteful use of ultrapure water and electric power can be avoided.

According one embodiment, a film forming apparatus includes a stage, a coating section, a vapor supply section, a blower section, and a controller. On the stage, an coating target is placed. The coating section applies a material to a predetermined region on the coating target placed on the stage to form a coating film. The vapor supply section generates solvent vapor capable of dissolving the coating film. The blower section blows the solvent vapor generated by the vapor supply section onto the coating film on the coating target placed on the stage. The controller controls an amount of the solvent vapor to be blown by the blower section so that: the coating film is dissolved; viscosity in a part of the coating film on a surface layer side is lower than that in a part thereof on the coating target side; and the viscosity in the part on the surface layer side and the viscosity of the coating target side take such values that prevent the coating film on the coating target from spreading.

According to one embodiment, an apparatus of processing a substrate includes a treatment chamber, a holder, a feed device, and a temperature control device. The holder is provided in the treatment chamber and is configured to rotatably hold the substrate. The feed device includes a nozzle configured to eject an etching solution to a surface of the substrate held by the holder. The temperature control device includes first and second devices, and a controller. The first device is configured to heat and/or cool an atmosphere inside the treatment chamber. The second device is configured to heat and/or cool the etching solution. The controller is configured to control operation of the first and second devices such that a temperature of the atmosphere is higher than that of the etching solution in the nozzle and that difference between the temperature of the atmosphere and that of the etching solution is maintained constant.
