Using the TS18IS manufacturing technology at foundry Tower Semiconductor Ltd, Chinese start-up Gpixel Inc. has designed and produced the industry's highest resolution CMOS image sensor.

 GMAX3005

Gpixel's 150 megapixel full-frame CMOS image sensor (GMAX3005) has a resolution of 30,000px by 5,000px and is intended for use in medical, industrial and scientific imaging markets.

The GMAX3005 is a monochrome CMOS image sensor capable of running at 10 frames per second at full frame and with even higher frame rates achieved in row-windowing mode. It has an electronic rolling shutter. Constructed using wafer-scale production techniques, it has a die size of 167.6mm by 30.1mm chip size including 165mm x 27.5mm photon-sensitive area. The GMAX3005 has a 16bit on-chip ADC with 12bit effective number of bits and 120 LVDS output pairs running at 200Mbit/s. The sensor consumes less than 2.5W at full frame rate in full resolution.

GMAX3005 has a dynamic range of 75.4dB and over 70 per cent quantum efficiency at 550nm wavelength.

"We chose TowerJazz's CMOS image sensor manufacturing process due to its excellent pixel performance, stitching technology for wafer-scale die size, and its outstanding pixel and process customisation capabilities," said Xinyang Wang, founder and CEO of Gpixel, in a statement. Tower Semiconductor trades as TowerJazz.

Gpixel was founded in 2013 by experienced CMOS image sensor designers and semiconductor physicists. The company has filed more than 10 patent applications, covering global shuttering, high dynamic range pixels, low-power and high-speed ADCs.
