in the manufacturing processes of liquid crystal display (LCD) panels and LEDs. While LEDs are used for general lighting and backlight for LCDs, the LED market in China is growing for such new applications as landscape lighting and large screens, in addition to general lighting.


Thus, SDK has strengthened its supply system to meet the growing demand for high-purity ammonia in East Asia, where electronics production sites are integrated.


SDK is operating three high-purity ammonia plants, one each in Japan, Taiwan, and China. Following the capacity expansion in China, SDK now has a total high-purity ammonia production capacity of 6,000 tons a year.


SDK’s high-purity ammonia production sites and their capacities, as of January 31st 2014 include:


1. Japan: SDK’s Kawasaki Plant (Kawasaki City) 1,500 t/y 2. Taiwan: Taiwan Showa Chemicals Manufacturing Co., Ltd. (Tainan City) 2,500 t/y


3. China: Zhejiang Quzhou Juhua Showa Electronic Chemical Materials Co., Ltd. (Quzhou City, Zhejiang Province) 2,000 t/y


Under its consolidated business plan PEGASUS Phase II, SDK classifies the semiconductor-processing high- purity gas business as a “Growth” business. SDK will aim to further globalise the business this year, strengthening the production/distribution system in Asia and expanding sales.


Block Engineering releases ultra-miniature QCL products


One of the III-V based laser systems is widely tuneable while the other can be used in a wireless mode


Block Engineering has released two ultra-miniaturised Quantum Cascade Laser (QCL) products, the Mini-QCL Module and the new LaserTune Infrared Source.


QCLs are fabricated using a number of III-V material systems. These include InGaAs/InAlAs, GaAs/AlGaAs, InGaAs/AlAsSb, InAs/AlSb and more recently Silicon/ SiGe.


The Mini-QCL is a widely-tuneable QCL module for Original Equipment Manufacturers (OEMs), weighing only 75 grams (~2.5 oz).


LaserTune infrared source


Scott Riggi, VP of Sales, comments, “We are receiving tremendous interest in these new products from universities, corporate R&D labs, and a wide range of OEMs. Block has now introduced the world’s most compact, full-function QCL source with the widest contiguous spectral tuning range. The demand for these devices in gas sensing, metrology, and academic and corporate R&D applications is significant.”


Petros Kotidis, Block’s CEO adds, “These two new products are the result of Block’s innovation spirit, engineering strength, and optical packaging capabilities. They meet a strong market need for ultra-compact, ultra- widely tuneable sources for OEM integration and all-in- one laser sources.”

Mini-QCL module


Block’s next-generation LaserTune has been miniaturised to a compact (16.5 × 12.7 × 11 cm), wirelessly-controllable system, while offering one of the widest contiguous tuning ranges available on the market (greater than 1000 cm-1).
