Clearly Brilliant, Clearly Powerful, Clearly Sapphire. For many years, two-inch and four-inch diameter sapphire wafers have been the standard for LED production. Now, LED manufacturers are moving to six-inch large diameter sapphire wafers. For further reading, visit the ClearlySapphire.com Blog,.

Clearly Brilliant, Clearly Powerful, Clearly Sapphire. Although it is typically associated today with high-tech applications such as LEDs and spacecraft windows, the production of industrial sapphire dates back to the late 19. Century, when A. V. L. Verneuil developed a flame fusion process to produce ruby and sapphire. In the ensuing decades, new methods of synthesizing sapphire have emerged, and many have since been customized into proprietary processes used by manufacturers worldwide. The physics invo...

Clearly Brilliant, Clearly Powerful, Clearly Sapphire. To address growing demand higher quantities as well as the need for cost reduction, LED manufacturers are migrating to large diameter sapphire wafers. Simply stated, the larger diameter substrates (six- or eight-inch, as opposed to traditional two-inch wafers) yield many more chips. For example, 10,000 six-inch wafers can yield the same number of LEDs as 100,000 two-inch wafers. For a graphic look at large diameter wafers and yield, download.

Clearly Brilliant, Clearly Powerful, Clearly Sapphire. As manufacturers of LEDs. Before the epitaxial layer is deposited for LED growth, a wafer’s surface morphology must be uniform. Wafer uniformity and flatness are paramount qualities – particularly in larger diameter (six- and eight-inch) sapphire wafers that are rapidly becoming the industry standard for substrates used to produce LEDs and silicon-on-sapphire.

Clearly Brilliant, Clearly Powerful, Clearly Sapphire. Sapphire in the LED Market. The LED market has been identified as a tremendous growth market. According to Yole Developpement, the LED industry grew by almost 75% in 2010 alone. Growth will continue through 2015 thanks to widespread adoption in LCD TV and General Lighting applications. There are three main segments in the LED market. Nearly half of flat-screen LCD TV and monitor panels shipped worldwide in 2011 will be illuminated by LEDs, a huge inc...

Clearly Brilliant, Clearly Powerful, Clearly Sapphire. History of the LED and Markets. Modern LEDs were invented in the early 1960s, but were limited in use. . The early low intensity little red lights were employed as indicator lights on industrial equipment. . As costs declined, they could be increasingly found in consumer electronics like clocks, watches, calculators and toys. Nissan decided to deploy LEDs for headlights electric-powered Nissan Leaf. In an effort to cut down headlight power consumpt...

Standards
http://www.clearlysapphire.com/Standards.html
Clearly Brilliant, Clearly Powerful, Clearly Sapphire. The move to large diameter sapphire wafers isn’t just a matter of making larger diameter wafer. . The laws of physics mean that larger diameter wafers need to get thicker in order to maintain their quality. . For example, six inch wafers need to be as much of three times thicker than 2” wafers, consuming three times as much base sapphire material to make the larger wafer. . The organization is working on standards for large diameter wafers.
