Title: Hiroyuki Hoshina: Innovator in Electroforming Technology
Introduction
Hiroyuki Hoshina is a prominent inventor based in Funabashi, Japan. He has made significant contributions to the field of electroforming technology, holding a total of four patents. His innovative methods have advanced the manufacturing processes in this specialized area.
Latest Patents
Hoshina's latest patents focus on a method of manufacturing electroforming molds. In this method, a first photoresist layer is formed on the upper surface of a bottom conductive film of a substrate. The first photoresist layer is then divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on the upper surface of the first photoresist layer within a predetermined temperature range, resulting in the formation of an intermediate conductive film. This intermediate conductive film is subsequently patterned. A second photoresist layer is formed on the exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, as well as on the upper surface of the remaining intermediate conductive film. The second photoresist layer is also divided into a second soluble portion and a second insoluble portion. Finally, the first and second photoresist layers are developed, and the soluble portions are removed, completing the process.
