Title: Akihiko Yokoyama: Innovator in Thin Film Technology
Introduction
Akihiko Yokoyama is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of thin film technology, holding a total of 4 patents. His work focuses on innovative methods for film formation, which have applications in various industries.
Latest Patents
Yokoyama's latest patents include a film forming method and apparatus designed for the formation of thin films on both surfaces of substrates, such as lenses. This method utilizes a pair of cluster beam evaporation sources that are positioned separately within a film forming chamber. The substrate is strategically placed between these sources to optimize the film formation process. Another notable patent is a cluster beam deposition method for manufacturing thin films. This method generates evaporated particles from a vapor source, clusters them, and deposits them onto a substrate in a vacuum atmosphere. The process is carefully controlled to maintain a partial pressure of water not exceeding 5 × 10⁻⁶ Torr, while keeping the substrate temperature at or below 150°C. This innovative approach results in films with high adhesion characteristics and mechanical strength without damaging the substrate.
