Rubicon Technology announced the publication of Opportunities for Sapphire, a new white paper that examines markets that leverage the highly versatile material, sapphire. Based on research from IMS Research, the paper takes an in-depth look at the demand for sapphire in key markets including LED, semiconductor and optical. You can find the white paper on Rubicon’s new web site at http://rubicontechnology.com/resources/papers, but here’s a look at what you’ll find.
Sapphire has emerged as a versatile material in a range of industries for many varied applications. Sapphire’s inherent physical attributes for durability, light transmission, chemical inertness and thermal insulation make it desirable for a growing list of applications in a range of markets. The white paper examines the opportunity for the LED market in general lighting, backlighting and display and uses in industries like automotive. It also explores sapphire applications for optical-grade sapphire windows, lenses and covers as well as semiconductor applications such as silicon-on-sapphire chips in radio frequency integrated circuits (RFICs) for RF antennas, as digitally tunable capacitors (DTCs) and power amplifiers in smart phones and other consumer devices.
According to white paper author Jamie Fox of IMS Research, high quality sapphire delivers great benefits to LED chip manufacturers gearing up for applications like LED-based general lighting. “Every LED company we spoke to during the research for this paper purchases sapphire and benefits from the superior yields and quality,” writes Fox. “Substrate demand in 2012 is estimated at 42 million two-inch equivalent wafers (TIE) and expected to grow to 57 million TIE in 2013 according to market research firm Displaybank. As the lighting market grows into a more significant segment and larger, thicker wafers are utilized, sapphire demand will accelerate.”
“Opportunities for Sapphire” also discusses the role of sapphire in LED production, the emergence of the market for large diameter sapphire wafers and sapphire demand by application.
