Latest Patents

Omura holds a patent for a method of producing a transparent conductive ZnO film. This method involves the formation of a film on a substrate using a chemical vapor deposition process. The process is characterized by feeding purified water and an organic metal material for Zn into a vacuum chamber, adjusting the gas pressure, and supplying diborane gas or a compound containing boron or aluminum. The substrate is heated to a prescribed temperature, and the film formation occurs under specific gas pressure conditions. Notably, the substrate is kept irradiated with ultraviolet light during the process. This innovative method allows for the production of a textured surface ZnO film with low resistivity, making it particularly suitable for use in thin-film solar cells.
