Title: Tetsuhiro Hatogai: Innovator in Nanoimprint Technology
Introduction
Tetsuhiro Hatogai is a prominent inventor based in Chiyoda-ku, Japan. He has made significant contributions to the field of nanoimprint technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
His latest patents include a nanoimprint stamper and a fine-structure transfer apparatus using the stamper. The nanoimprint stamper is designed to conform to two types of anomalies in the shape of a transfer substrate, such as warpage and surface protrusions. This technology allows for a transfer process that minimizes defects and ensures uniformity. The stamper consists of several components, including a light-transmitting rigid substrate, a resilient plate, a flexible rigid stamper base, a stamper buffer layer, and a patterned stamp layer. Notably, the stamper buffer layer has a lower Young's modulus than the patterned stamp layer, enhancing its performance.
Additionally, Hatogai has developed a nanoimprint resin stamper intended for use in optical transfer-based nanostructure transfer apparatuses. This resin stamper is capable of automatic transport and alignment, featuring a support member made of a light-transmitting material, an intermediate layer, and a patterned resin layer. The design ensures that the support member is larger than the other layers, while the intermediate layer is more flexible than the patterned resin layer.
