Currently the heavy flavour factory KEKB located at the KEK accelerator centre in Tsukuba, japan, is being upgraded to the Super KEKB factory, aiming for a substantially higher luminosity of 8 x 10(35) cm(-2) s(-1). This by a factor of 40 increased luminosity that requires significant modifications of the Belle detector. The vertex detector needs to be redesigned and, besides a four-layer silicon strip detector, a pixel detector based on the DEPFET technology will be installed closest to the interaction point. The requirements for this pixel detector, the DEPFET technology and the current status of the pixel detector will be presented in this paper.
