First large DEPFET pixel modules for the Belle II Pixel Detector — •Felix Müller1, Ladislav Andricek2, Paola Avella1, Christian Kiesling1, Christian Koffmane1, Hans-Günther Moser1, Rainer Richter2, and Manfred Valentan1 for the Belle II collaboration — 1Max-Planck-Institut für Physik, München — 2Halbleiterlabor der Max-Planck-Gesellschaft, München
DEPFET pixel detectors offer excellent signal to noise ratio, resolution and low power consumption with a low material budget. They will be used at Belle II and are a candidate for an ILC vertex detector. The pixels are integrated in a monolithic piece of silicon which also acts as PCB providing the signal and control routings for the ASICs on top. The first prototype DEPFET sensor modules for Belle II have been produced. The modules have 192000 pixels and are equipped with SMD components and three different kinds of ASICs to control and readout the pixels. The entire readout chain has to be studied; the metal layer interconnectivity and routings need to be verified. The modules will be fully characterized and the operation voltages and control sequences of the ASICs will be investigated. An overview of the DEPFET concept and first characterization results will be presented.
