1.75um Pixel in Sony CCDs

Sony quitely released new CCDs: 8.15MP with 1.75um pixels and 12.19MP with 1.85um pixels.

The ICX636/646 series which features 1.75um pixels, is said to use finer process features to increase the aperture ratio per unit pixel by 9% from the existing 1.86um pixel ICX629. It allowed Sony to achieve equivalent levels of sensitivity, saturation signal level, and smear characteristics as the existing ICX629 despite the reduced pixel size.
