his primer is intended for those involved with CCD image sensing applications wishing to obtain additional insight into the
mechanisms of CCD sensor principles and operations. It is not intended to provide an exhaustive study into the detailed
theory behind the subject and it is assumed that a silicon based CCD is used unless otherwise stated. It is also assumed
that a conventional front illuminated detector system is employed. Some references are listed at the conclusion.
Like many technologies, the Charge-Coupled Device (CCD) started out as one kind of creature and wound up as something
completely different. Invented in the late 1960's by researchers at Bell Labs, it was initially conceived as a new type of
computer memory circuit, and it was demonstrated in 1970 for  that facility. It soon became apparent that the CCD had
many other potential applications, including signal processing and imaging, the latter because of silicon's light sensitivity
that responds to wavelengths less than 1.1µm (the visible spectrum falls between 0.4µm and 0.7µm).  The CCD's early
promise as a memory element has since disappeared, but its superb ability to detect light has turned the CCD into the
premier image sensor technology.
Similarly to integrated circuits (IC), CCDs begin on thin silicon wafers that are processed with a series of elaborate steps,
which define the various functions within the circuit. Each wafer contains several identical devices (“chips”), each capable
of yielding a  functional device. Selected chips, based on a  variety of preliminary screening  tests, are then cut from the
wafer and packaged into a carrier for use in a system.
The scope of  this primer is to introduce the reader to the basics of CCD imaging. The qualitative discussions described
herein reflect silicon based imaging applications in the visible spectrum.
