John,

This idea has been tried by a company called Silicon Film
(http://www.siliconfilm.com). Due to low demand and financial trouble, the
company is contemplating bankruptcy.

The challenge is not in manufacturing a CCD of decent "resolution", there
are already 5 and 6 megapixel sensor that are MUCH smaller than 24x36mm. The
challenge resides in designing a sensor that is thin enough so that it's
thickness does not affect the image quality in the corners (since rays are
'bent' more sharply).
