Because of the continuing rapid demands of LED production in Taiwan and China, Johnson Matthey, the designer and manufacturer of hydrogen purifiers, has shipped its purifiers to new and expanding fabs for LED production.

 It’s said that Johnson Matthey's state-of-the-art PSH Series bulk hydrogen purifiers can provide 99.9999999% pure hydrogen for wafer fabrication. And the HP Series purifier product line is the most popular and provides the purest hydrogen.

 According to Stuart Bestrom, Sales Manager for Johnson Matthey’s Gas Purification Technology (GPT) group, the company has supplied purifiers to two major high-tech manufacturers in China,.

One focuses on the development and large-scale production of ultra-high brightness red, orange and yellow LED epitaxy and chips, light communication components as well as other optoelectronic devices. Another purchased several Johnson Matthey Model PSH-60 purifiers capable of hydrogen flows of 60 Nm3/hr.
 
For Taiwan, among the major customers who have purchased several Model PSH-60 purifiers is a leading maker of pure-play, high power InGaN LED wafers and chips, and the only one in Taiwan offering a full spectrum of products including high power InGaN blue, green and near-UV LEDs. Another is using Johnson Matthey purifiers to supply ultrapure hydrogen to its growing number of high throughput MOCVD tools.
