  The SemiConductor Tracker (SCT) together with the Pixel detector and the
Transition Radiation Tracker (TRT) form the central tracking system of the
ATLAS experiment at the LHC. It consists of single-sided microstrip silicon
sensors, which are read out via binary ASICs based on the DMILL technology, and
the data are transmitted via radiation-hard optical fibres. After an overview
of the SCT detector layout and readout system, the final-stage assembly of
large-scale structures and the integration with the TRT is presented. The focus
is on the electrical performance of the overall SCT detector system through the
different integration stages, including the detector control and data
acquisition system.
