Abstract
Feasibility of obtaining CCD image sensors with a small image size, such as 1/2 inch or 8mm, has been investigated using the conventional 2/3 inch design and process technology. For estimating the expected characteristics for reduced image size sensors, a 2/3 inch interline transfer CCD was fabricated, in which the horizontal function was designed compatible with a 1/2 inch device. It was deduced that the reduction in the image size, using the 2/3 inch technology, could be made without deteriorating the practical imager performance. Based on these results, an 8 mm size sensor with the FIT-CCD configuration has been designed, fabricated and evaluated. Most of the characteristics obtained are on levels with those expected. Note that the smearing level has been strinkingly lowered, as a result of the FIT-CCD configuration.
