A 1/4-inch 380 k-pixel IT-CCD image sensor

Abstract

A 1/3-inch 360 kpixel IT-CCD image sensor has been developed to satisfy recent demand for small CCD image-sensors with higher resolution and higher sensitivity. The photo-diode aperture and the microlens structure were optimized using microlens simulation technology. As a result, a minimum object illumination of 3 lux and a low smear level of 0.002% have been achieved.
