High-speed scientific CCDs: substrate bounce

A synergy of digital imaging technologies is taking place that is expanding CCD applications and markets in the high speed arena. Discussions in this paper are directed toward requirements for a new class of High Speed Scientific CCDs. This paper will discuss the theoretical limits in readout rate for maintaining high performance in the areas of charge transfer efficiency and dynamic range. In particular, a high sped problem called 'substrate bounce' is discussed which represent an important speed limitation for the CCD, especially for backside illuminated sensors. Theoretical results are compared to experimental data taken from developmental HSS CCDs recently fabricated.
