Title: Innovations by Yuichiro Sano

Introduction

Yuichiro Sano is a notable inventor based in Mito, Japan. He has made significant contributions to the field of circuit pattern formation, holding a total of 5 patents. His work focuses on improving the efficiency and effectiveness of circuit pattern transfer methods.

Latest Patents

One of his latest patents is a "Circuit pattern formation device and method of forming circuit pattern." The purpose of this invention is to provide a method for transferring a pattern of a circuit pattern precursor formed of electroconductive particles containing no resin component onto an objective substrate with high transfer efficiency while retaining the pattern shape. This method involves temporarily removing a liquid film around the circuit pattern precursor after a development step, re-electrifying the electroconductive particle pattern by supplying a solvent, and then electrostatically transferring the pattern onto the objective substrate through electrophoresis in the solvent.

Another significant patent is the "Circuit pattern formation device and method of forming circuit pattern to substrate." This invention aims to improve the adhesion strength between a circuit pattern and its substrate without increasing the resistance value of the circuit pattern. The device forms a precursor circuit pattern on the surface of a dielectric thin film body and transfers it to a target substrate. The process includes forming an electrostatic latent image, exposing it using an exposure unit, and supplying a conductive particle dispersion solution to create a precursor circuit pattern. The precursor is then temporarily transferred to a circuit pattern holding substrate, heated, and finally released to transfer to the target substrate.
