Patterned Sapphire Substrates

Rubicon Technology, Inc., the global leader in large-diameter sapphire substrates, has leveraged its unique expertise to create a complete line of Patterned Sapphire Substrates—PSS—in 4” through 8” diameters. Our facility and equipment are state-of-the-art, including our Class 100 clean room and advanced metrology tools. 

We offer fully customizable sub-micron patterning capability with tight dimensional tolerances, within ± 0.1 μm, high-precision control of pattern dimensions, and very high uniformity from wafer to wafer. With an edge exclusion zone as small as 1 mm, Rubicon provides you more usable area to maximize the number of chips per wafer.
