A progressive scan CCD imager for DSC applications

A progressive scan CCD imager implemented in standard double layer polysilicon CCD for digital still camera (DSC) application, is designed on the pixel interleaved array (PIA) CCD architecture. It arranges the pixels spatial phase alternation by line. It has over 1.4 M pixels integrated zigzag with 3.2 /spl mu/m pitch horizontally and vertically. The unit pixel is diamond shape and is 4.52/spl times/4.52 /spl mu/m/sup 2/. Typical example of color filter arrangement is also shown. Green filter covers the pixel located on square lattice point. Red and Blue filters alternatively cover the spatial phase shifted pixels. Diamond-shaped micro lens is formed on top of each pixel.
