JMAR Awarded Additional $2.1 Million Funding for X-Ray Mask Program; Award Supports X-Ray Microscope and X-Ray Nano Probe Instrument Research and Development.

SAN DIEGO -- JMAR Technologies, Inc. (NASDAQ: JMAR) today announced that the U.S. Government's Naval Air Warfare Center has awarded its Systems Division an additional $2.1 million in funding to procure sub-100nm feature X-ray masks for next-generation lithography, and to produce Zone Plate optics for X-ray Microscopes and X-ray Nano Probes.

The X-ray masks developed through this program will be used to demonstrate fabrication of high-density CRAM using X-ray lithography with 35-50nm contact holes for high-priority military and space applications. The X-ray masks will also produce X-ray optical elements known as "Zone Plates" which carry out the same functions as lenses for visual wavelength light, and are key components of X-ray Microscopes and X-ray Nano Probe tools.

"This funding enables JMAR to continue its support of X-ray mask infrastructure and to show off X-ray lithography's ability to print sub-50 nanometer resolution, high aspect ratio holes, in this case for CRAM chip fabrication," said Ronald A. Walrod, CEO of JMAR. "Between the X-ray source R&D work carried out for DARPA at our Research Division in San Diego, and the X-ray optics work supported by this new round of funding, JMAR is well positioned to produce advanced X-ray instruments for defense and commercial applications."
