INNOTECH announced that it has licensed its cutting-edge, solid-state device VMIS image sensor technology to Sharp Corporation. Sharp is developing an advanced image sensor that uses VMIS to achieve low power consumption and high image quality to meet the growing requirements of cameras for cell phones, PDA’s and other mobile devices in near future. Highly acclaimed, VMIS technology enabled image quality as close as CCD levels with CMOS-like VMIS process featured in low power consumption.
VMIS (Threshold Voltage Modulation Image Sensor) is a sensor that alters the MOStransistor threshold voltage with electric charge generated by light reception and outputsthis change in threshold voltage as the image signal. VMIS technology features both lowpower consumption and advanced picture quality. The performance differs radically fromthat of conventional CMOS sensors and incorporates a unique state of the art in devicemechanism. With VMIS technology, photoelectric conversion process can be achieved withmuch lower noise compared to conventional CMOS image sensors, and high sensitivity andhigh image quality can be obtained with low voltage and low current. Image sensors rangingfrom low pixel CIF and VGA-class sensors to high multi-mega pixel sensors can bemanufactured with existing CMOS like VMIS processes.
