The DØ collaboration is completing production of a 793 000 channel silicon strip tracking system for the DØ upgrade. The tracker consists of 768 ladder and wedge assemblies including both single- and double-sided detectors. The production process includes burn-in of electronics, mechanical assembly under coordinate measuring machines, wire bonding, repair of bad channels, detector burn-in, laser testing, and final assembly. We describe observed failure modes of the detectors, including microdischarge and lithography defects. We present results of the production and testing process and describe the anticipated performance of the detector. Lessons for future production of large-scale tracking systems are discussed
