The high luminosity SuperB asymmetric e+e−e+e− collider, to be built near the INFN National Frascati Laboratory in Italy, has been designed to deliver a luminosity greater than 1036 cm−2 s−1 with moderate beam currents and a reduced center of mass boost with respect to earlier B-Factories. An improved vertex resolution is required for precise time-dependent measurements and the SuperB Silicon Vertex Tracker will be equipped with an innermost layer of small radius (about 1.5 cm), resolution of 10–15μm in both coordinates, low material budget (<1%<1% X0), and able to withstand a background rate of several tens of MHz/cm2. The ambitious goal of designing a thin pixel device with these stringent requirements is being pursued with specific R&D programs on different technologies: hybrid pixels, CMOS MAPS and pixel sensors developed with vertical integration technology. The latest results on the various pixel options for the SuperB SVT will be presented.
