Paper Abstract

The demand for higher red wavelength sensitivity is being met by various technological developments of modern CCDs. We discuss techniques for achieving higher red wavelength sensitivity by using thicker silicon to make backthinned CCDs, which combines with very low read noise for enhanced sensitivity. Thicker devices requires higher resistivity material including bulk (non epitaxial) silicon. An extended wavelength range also places more demand on the antireflection coatings which benefit from corresponding optimisation.
