Established in 1972, Yongguang Chemical is committed to the development of electronic chemistry, providing photoresists, developing solutions for the LCD, LED, and IC semiconductor industries, as well as key chemicals such as polishing fluids, polishing fluids, and cleaning fluids for polishing processes. The supply of products has become the only supplier of domestic IC photoresists in China. During the 2010 Taiwan Flat Panel Display Exhibition, Everlight will exhibit the latest key photoresist and developer products for LED and LCD at the C 1116 booth of World Trade Center.
Looking back on the achievements in 2009, Everlight has made further gains in the field of touch, LCD and LED. Chen Guangwang, general manager of Yongguang, said that touch technology applications have spread all over the consumer electronics, the key to the Touch PanEL process. Chemicals, Everlight has completed the development of Add-On Type and On Cell Type insulation-level protective layer photoresist products with high hardness (5H), good metal adhesion (>4B) and high water wash resistance (>4B). ), excellent boring capacity and other characteristics, Yongguang has also been commercialized in the mass production supply market.
In addition, the transparent protective material for touch panels has entered the production line of Japanese manufacturers. In the layout of the touch industry, Yongguang products have already obtained orders from core manufacturers. Yongguang is confident in supplying related products for the touch industry. Indirect profit will be paid for revenue as the scale of touch products on the market expands.
In the LCD industry, Yongguang completed the commercialization of LTPS TFT LCD low-temperature polysilicon photoresist in 2009. This product is a highly technical process product with low n-light energy, high resolution and high heat resistance. Some manufacturers are already using it, but because of the high cost of such products, the demand has not yet fully responded. In time, when the process is more mature and the cost is lower, the demand will inevitably follow.
Chen Weiwang pointed out that in view of the ever-increasing color saturation requirements of TFT LCD liquid crystal display screens, Yongguang will introduce a high-concentration developing solution for color resists in 2009, which can improve the residue residue residue, has high dilution, and can reduce customer production. The cost is a developer standard used with a new generation of color photoresists. This product is in a state of layout this year. Yongguang believes that after two or three years, the product will start to ferment.
As for the LED industry with the most potential in the cross-strait market, Yongguang has been able to provide Wafer polishing slurry for LED, Lift Off Process photoresist and LED chip encapsulant, and high-end LED photoresist (Lift-off) product ENPI 2= The series of photoresists can eliminate the process of strong acid precious metals and meet the energy saving, carbon reduction and green environmental benefits.
In LED chip encapsulant, Everlight has a series of products with anti-UV and yellowing resistance. This kind of product can be used in high-luminous LED bulbs at reasonable price, which can make LEDs stable for a long time.
Chen Weiwang said that in the LED industry, Yongguang has a complete supply capacity of the upper, middle and lower reaches. Not only from the polishing slurry of the upstream substrate, to the supply of special chemicals such as midstream photoresist and developer, but also to the downstream packaging adhesive, it also actively introduces key packaging materials, such as chemistry that has accelerated the development of energy saving and environmental protection requirements. Products, hope to achieve long-term effect characteristics, and high-quality LED package products. At present, the upstream and middle reaches of LED is the main supply side of Yongguang, and in 2010, there will be more active layout in the LED packaging market, and there will be a higher growth performance.
In 2010, the goal of Yongguang's electronic chemistry business will focus on the TFT-arrray positive-type photoresist development project EPL 360 series and EPL 380 series photoresist, and develop Spinless and I-line photoresist. Spinless is mainly aimed at the current glass substrate size. The trend is to make the photoresist evenly coated on the glass substrate without the spinner.
In addition, Everlight has successfully developed TFT-arrray I-line photoresist. I-line photoresist is mainly used to meet the requirements of thin-filming of TFT array design. It can be used with I-line Stepp= exposure machine for yellow light lithography process. The customer is provided in a 1.5 micron design process and the product has been certified by the customer.
