Solid-State MAPD Photo Detectors Achieve Commercial Production Status

Zecotek Announces Significant Manufacturing Breakthrough With Solid-State MAPD Photo Detectors

Singapore, February 9, 2012 - Zecotek Photonics Inc. (TSX-V: ZMS; Frankfurt: W1I),a developer of leading-edge photonics technologies for medical, industrial and scientific markets, today announced that it has achieved commercial production status with its most advanced solid-state Micro-pixel Avalanche Photo Diode (MAPD) photo detectors MAPD-3N. The MAPDs are manufactured under contract by the Malaysian Institute of Microelectronic Systems and Omega Semiconductor Sdn Bhd (MIMOS). Fine tuning of pre-production runs over the last 6 months has resulted in MIMOS stabilizing the manufacturing process and the MAPD-3N is now ready for commercial production.

“MIMOS has done a commendable job stabilizing the manufacturing process of our proprietary MAPD photo detectors which are now ready for commercial production,” said Dr. A.F. Zerrouk, Chairman, President, and CEO of Zecotek. “The MAPD-3N features superior photon detection efficiency, energy and timing resolutions and working gain when compared to existing photo multiplier tubes (PMT). These areonreached mutual agreement critical requirements for PET (positron emission tomography) scanning devices and high energy physics applications. Customers of our solid-state MAPD photo detectors are impressed with the performance and cost advantage offered and we are now in the position to deliver units on a commercial basis.”

Zecotek’s proprietary MAPD-3N is a design upgrade of the previously announced MAPD which offers significant performance advantages over competing photomultiplier tubes (PMT). The solid-state MAPD photo detector features the highest linearity and dynamic response as compared to existing PMTs. The improvement in photon detection efficiency and working gain by a factor of 2, and the reduction of dark count rates by almost a factor of two, make the universal adoption of solid-state detection technology in advanced, high-resolution PET medical scanners and gamma camera applications, a reality, particularly when the MAPD-3Ns are matched with Zecotek’s patented LFS scintillation materials. Zecotek’s pioneering MAPD technology can be used to manufacture two-dimensional arrays of solid-state photo detectors, another significant advancement, which allows for the manufacture and implementation of both very large-area detectors and compact position-sensitive arrays, which will likely displace expensive and bulky position-sensitive PMT’s.

The MAPD-3N is supplied to customers through Zecotek Imaging Systems Pte. Ltd., Singapore, a wholly owned subsidiary of Zecotek Photonics Inc., and manufactured under contract by the Malaysian Institute of Microelectronic Systems and Omega Semiconductor Sdn Bhd.
