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.

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.

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.

Lin Jun Pharmaceutical Industry Co., Ltd. has recently started handling a high-performance etching solution that can etch and roughen the surface of GaN films (N-face) in the blue light-emitting diode process. By roughening the surface, the light extraction efficiency is improved, resulting in a higher luminous efficiency. Our company will continue to propose environmentally conscious functional chemicals to many companies to support the improvement of luminous efficiency in blue LEDs. □ For other functions and details, please refer to the materials.

We will be showcasing our etching solutions for forming uneven surfaces on blue LED GaN films released this year, as well as etching solutions for forming uneven surfaces on yellow-green to red LED AlGaInP films, GaP films, GaP substrates, AlGaAs films, and GaAs substrates released last year, in addition to etching solutions for insulating films and various metal films. We cordially invite you to visit the Sumitronics booth and take a look.

Lin Jun Pharmaceutical Industry Co., Ltd. has recently developed a damage-free aluminum (Al) etching solution for silicon oxide and silicon nitride (insulation film) etching. By using this etching solution, it becomes possible to etch insulation films without corroding Al or Al alloys, eliminating the need for processes to protect Al or Al alloys, which can improve the overall throughput of the manufacturing process. Our company will continue to propose functional chemical solutions that emphasize energy savings and cost reduction through process shortening to many companies.

Our company will be showcasing at SEMICON Taiwan 2011, featuring Si anisotropic etching solutions, Al tapered etching solutions, and this year's releases including green to red LED AlGaInP films, GaP films, GaP substrates, AlGaAs films, GaAs films, GaAs substrates, as well as roughening etching solutions for single crystal silicon solar cells. We invite you to take this opportunity to visit the SUMITRONICS TAIWAN booth. Event Dates: September 7 (Wednesday) to September 9 (Friday), 2011 Opening Hours: 10:00 AM to 5:00 PM (September 7 and 8) 10:00 AM to 4:00 PM (September 9) Venue: Taipei World Trade Center (TWTC) Hall 1 No. 5, Section 5, Xinyi Road, Taipei City 110 Exhibition Location: SUMITRONICS TAIWAN Booth #495 and #496 Official SEMICON Taiwan Website: http://www.semicontaiwan.org/en/

Lin Jun Pharmaceutical Industry Co., Ltd. has recently developed an etching solution for texture (roughness) formation processing for monocrystalline silicon solar cells. By using this etching solution, it has become possible to effectively and easily form textured structures on monocrystalline silicon surfaces without the use of special techniques. Our company will continue to propose environmentally conscious functional chemicals to many companies, supporting the improvement of conversion efficiency in solar cells, which are expected to expand rapidly. □ For other functions and details, please refer to the materials.

Lin Jun Pharmaceutical Industry Co., Ltd. has recently developed an etching solution that allows for the easy formation of desired surface roughness on AlGaAs and GaAs semiconductor films and substrates, as well as GaP semiconductor films and substrates in the LED process, without the use of special techniques. Our company will propose functional chemical solutions that focus on improving LED luminous efficiency and supporting energy-saving in various devices to many companies. □ For other functions and details, please refer to the materials.

We have successfully developed a high-performance etching solution that can etch and roughen the surface of AlGaInP films (semiconductor films) in the LED (light-emitting diode) process. By applying this etching solution, it has become possible to efficiently etch and roughen the surface of the semiconductor film that constitutes the light extraction surface of the LED without using any special techniques. In the future, this is expected to contribute to the enhancement of brightness, processing precision, and reliability of LED products, which are anticipated to experience high growth, and we plan to propose and sell it not only for LED manufacturing but also for various other fields. □ For other functions and details, please refer to the materials.
