Hayashi Pure Chemical Ind., Ltd. Electronic Materials Official site

We are pleased to announce that Hayashi Junyaku Kogyo Co., Ltd. has developed UHP grade PGMEA, guaranteed to contain metal impurities of 33 elements at less than 50 ppt. We have installed small-scale production equipment at our Mie factory and have begun sample work. This grade is proposed for use in fields requiring ultra-low metal content, such as semiconductor materials and ultra-trace element analysis. <Features> - Low metal content through purification Guaranteed to contain 33 elements at less than 50 ppt - Metal assurance through high-precision analysis Introduction of ICP-MS/MS and improvement of analytical techniques - Thorough quality control Clean management from manufacturing environment to supply containers - Compatible with various containers 500ml, 20L, 200L poly containers 18L canisters, etc. - Second phase in development PGME, ethyl lactate, and others □ For other functions and details, please refer to the documentation.

We are pleased to announce that Hayashi Junyaku Kogyo Co., Ltd. has published the "Functional Chemical Solutions Catalog" for the electronics industry on July 22, 2013 (first edition). The catalog includes a variety of metal film etching solutions, stripping solutions, and developing solutions, as well as various products for textured etching solutions for solar cells and roughening etching solutions for LEDs, which have been gaining attention in recent years. We invite you to take a look at this opportunity.

Lin Jun Pharmaceutical Industry Co., Ltd. has developed a crystal etching solution for crystal devices. Etching solutions commonly used for wet etching of crystals include hydrofluoric acid (HF) and a mixed solution of HF and ammonium fluoride (NH4F), but they have various issues. Therefore, our company has developed a crystal etching solution that reduces the angle difference in taper angles of cross-sectional shapes due to etching, enabling the flattening of the etched surface and uniform etching thickness through our unique technology. □ For other functions and details, please refer to the materials.

Our company will be showcasing various etching solutions, including silver nanowire etching solution (for ITO alternative transparent conductive films) and GaN film (N-face) roughening etching solution (for blue LEDs), at the SUMITRONICS TAIWAN booth during SEMICON Taiwan 2012. We cordially invite you to stop by and take a look at this opportunity.

Lin Jun Pharmaceutical Industry Co., Ltd. has developed a high-performance etching solution that can etch silver nanowires, which are a transparent conductive film alternative to ITO. Silver nanowire transparent conductive films are gaining attention in the touch panel field as a substitute for ITO, and their development is being actively pursued. However, due to the characteristic that the wiring patterns are more easily visible compared to ITO, technology is needed to make the wiring patterns less visible during product commercialization. Therefore, our company has developed an etching solution that can make the wiring patterns less visible through our unique technology. □ For other functions and details, please refer to the materials.
