Audience: Not Specified Intended Educational Use: No Abstract / Description: DEPFET pixels offer a unique possibility for a high resolution pixel vertex detector at a future linear collider (ILC) experiment. The key idea of DEPFET sensors is the integration of amplifying transistors into a fully depleted bulk. The excellent noise performance obtained through the low input capacitance in combination with the full signal from the depleted bulk leads to a large S/N ratio. The sensor itself can therefore be made very thin (50mm) without loss of efficiency. In this article the progress of the DEPFET development towards an ILC vertex detector is presented. Properties of prototype matrices and dedicated ASIC electronics have been characterized in various laboratory and test beam measurements. In particular a point resolution of less than 2 mm has been demonstrated (using 450 mm thick sensors). Based on these results larger matrices, improved readout and control electronics have been designed which are presently in production. In parallel software was developed to simulate the performance of a DEPFET based vertex detector in an ILC experiment.
