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.
