Production of the ATLAS pixel detector modules

The ATLAS experiment will make use of a pixel detector in the innermost part of its semiconductor tracker. The pixel detector consists of three cylindrical layers in the barrel part and three disks in the forward and backward parts. Modules are the building blocks of the detector. There are 1456 modules in the barrel and 288 in the end-caps. They are all identical to simplify construction and maintenance. The installation of the pixel detector in the experiment is foreseen early in 2006 and the module production should be finished in the fall of 2005. In this paper the status of the module production is reported, focusing on the problems we have found in this large-scale production.
