BENSENVILLE, Ill. -- October 29, 2013

Rubicon Technology, Inc. (NASDAQ:RBCN), a leading provider of sapphire
substrates and products to the LED, semiconductor, and optical markets, today
announced the launch of the first commercial line of large diameter patterned
sapphire substrates (PSS) in four-inch through eight-inch diameters. This new
product line provides LED chip manufacturers with a ready-made source of large
diameter PSS to serve the needs of the rapidly growing LED general lighting
industry.

Growth of the LED general lighting market is expected to expand from nearly
300 million lamps shipped in 2012 to 3 billion by 2020 according to IMS
Research. Technology innovation is helping the LED supply chain prepare for
this dramatic growth. Most high-brightness LED manufacturers etch a pattern
into the sapphire wafers in order to both improve epitaxial growth and extract
more light from each chip. Patterned sapphire substrates have been available
for purchase in smaller diameters, but Rubicon is the first to offer highly
customizable 6” and 8” PSS. The larger substrates increase chipmakers’
throughput and efficiency.

“As LED-based general lighting gains worldwide adoption, large-diameter
patterned sapphire substrates will become necessary to meet the demands of the
rapidly growing lighting market,” said Raja M. Parvez, president and CEO of
Rubicon Technology. “Rubicon has developed an unmatched technology platform
that is vertically integrated from raw material through crystal growth, large
diameter polished wafers, and now custom PSS in 4”, 6” and 8” diameters. Our
vertical integration enables Rubicon to produce progressively larger sapphire
products while providing customers with exceptional quality, cost control,
reliability, and consistency.”

Rubicon offers fully customizable sub-micron patterning capability with tight
dimensional tolerances, within ±0.1 µm. With an edge exclusion zone as small
as 1 mm, Rubicon offers LED chip manufacturers more usable area to maximize
the number of chips per wafer. Patterning is available in a range of shapes
including cone, dome and pyramid, and in a range of orientations. Further
customization of geometry, pattern and orientation is available upon request.
