Structure of a CCD 2.
CCDs are are manufactured on silicon wafers using the
same photo-lithographic techniques used
to manufacture computer chips. Scientific CCDs are very big ,only a few can be fitted
onto a wafer.
This is one reason that they are so costly.
The photo below shows a silicon wafer with three large
CCDs and assorted smaller devices. A CCD has
been produced by
Philips that fills an entire 6 inch wafer! It is the worlds largest integrated
circuit.
