Plus, from the little I know about chip making, it would be extremely expensive and non-standard.
Chips are not moulded or machined into shape. They are made in big batches, by letting certain elements penetrate into a silicon wafer under the right circumstances. Trying to make them concave would probably yield even a smaller proportion of good chips per wafer than when making big format CCDs. j On 10/20/06, John Francis <[EMAIL PROTECTED]> wrote: > On Fri, Oct 20, 2006 at 10:32:46AM -0700, Jack Davis wrote: > > Would it make sense to develop a concave sensor?
