Latest Patents

**LCD TFT Drain and Source Electrodes Having Ohmic Barrier.** This invention describes a matrix display in which address and data wiring layers cross at right angles, with a TFT at each intersection. The TFTs connect to display electrodes in their respective regions. The wiring layers and TFT source and drain electrodes use a three-layer structure: an ohmic barrier layer, a conductive layer for carrying signals, and a layer that helps prevent battery-related reactions.

**Sputtering Apparatus.** This invention describes a sputtering system with a pressure-resistant vessel, a substrate, a target, and a magnet that confines plasma near the target surface. A conductive, plate-shaped anode sits between the substrate and target and has an opening larger than the substrate’s profile. A power supply provides sputtering current between the anode and target.

Career Highlights

Ohno’s listed company affiliations include Casio Computer Co., Ltd. and Oki Electric Industry Co., Ltd. The patent descriptions provided highlight technical contributions to display-device wiring and thin-film deposition equipment.
