Title: Toshiyuki Numazawa: Innovator in Contact Probe Technology
Introduction
Toshiyuki Numazawa, a notable inventor based in Hyogo, Japan, has made significant contributions to the field of technology with his innovative approaches in manufacturing contact probes and microstructures. With a total of 2 patents to his name, Numazawa has demonstrated his prowess in utilizing advanced materials and techniques in his inventions.
Latest Patents
One of Numazawa's latest patents is focused on the **Contact Probe** and a method for its manufacturing. This innovative technique includes several steps, starting with an electroforming step that uses a resist film arranged on a substrate as a pattern frame corresponding to the contact probe's shape. The process fills the gap in the resist film to form a metal layer. Additionally, there is a tip end shaping step that involves obliquely removing and sharpening the metal layer's tip end portion. Finally, a take-out step is implemented to extract the metal layer from the pattern frame.
His second patent relates to a **Method of Forming a Microstructure** and an **X-ray Mask**. It describes a method for creating a microstructure with a higher aspect ratio utilizing a general-purpose synchrotron orbital radiation apparatus. A resist layer, incorporating a copolymer of methyl methacrylate and methacrylic acid, is applied onto a substrate. The process further involves lithography with synchrotron radiation to develop a resist pattern, followed by normal electroplating or electroforming, resulting in a microstructure with significant aspect ratio.
