Rubicon Technology, a provider of sapphire substrates and products to the LED, semiconductor, and optical industries, today announced the closing of a three year $25 million secured revolving credit facility with Silicon Valley Bank.

“This undrawn credit facility bolsters Rubicon’s strong liquidity position,” said William Weissman, chief financial officer of Rubicon Technology. “We believe it is prudent to establish this additional financial flexibility for the future,” he concluded.
