摘要： An electrode substrate is brush cleaned with a hydrogen gas dissolved water, which has an oxidation-reduction potential of −860 mV to −400 mV and a pH of 8 to 12, before applying an alignment layer material on the electrode substrate. Thus, it is possible to decrease the manufacturing costs without decreasing the detergency.

摘要： A method of water electrolysis for producing acidic water and alkaline water is disclosed, which is effective in preventing the dissolution of electrode material in the acidic water, etc. attributable to a reverse current flowing in a power supply cutoff state and also in preventing electrode deactivation caused by the electrode material dissolution. This enables the electrolytic cell to be operated stably over a long period of time to yield high-purity acidic and alkaline waters. An electrolytic cell 1 partitioned into an anode chamber and a cathode chamber with a cation-exchange membrane 2 as a solid electrolyte is used to electrolytically produce acidic water and alkaline water. A voltage of 1.2 V or higher and/or a current of 20 mA/dm.sup.2 or higher is applied between the anode 7 and the cathode 8 when the electrolytic cell is in a power supply cutoff state.

摘要： A copper-based metal polishing solution comprises a water-soluble organic acid capable of reaction with copper to form a copper complex compound which is unlikely to be dissolved in water and has a mechanical strength lower than that of copper. The polishing solution also contains polishing abrasive grains and water. The polishing solution of the particular composition does not dissolve at all copper or a copper alloy when a copper or copper alloy film is immersed in the polishing solution, and permits polishing the copper or copper alloy film at a practical rate in the polishing step.
