During the last few years a large number of Silicon Microstrip Detecto
rs have been especially designed and tested by the CMS collaboration i
n order to study and optimize the performances of the tracking devices
to be used in the inner part of the experiment. Both single and doubl
e sided silicon detectors of different shapes and strips configuration
, including prototypes produced with double metal technology, have bee
n exposed to high energy beams. The main results on detector performan
ces (charge response, signal to noise ratio, spatial resolution etc.)
will be reviewed and discussed.
