“…Residual fraction of Al substrate with a thickness of 100 nm or more is almost impervious to UV light and cannot be used as translucence APA molds if more than 100 nm of residual Al remains between the mold and the support layer. 42 Fig. 2(b) and (c) show the surface and cross-sectional SEM images of the resulting translucent APA mold.…”

“…The quantum efficiency for X-rays is in the whole energy band from 0.3 keV to 12 keV at least 90 % for the 500 P thick PN-CCD 10 . In the domain of visible light and near infrared a similar high quantum efficiency is obtained (see Figure 3).…”

“…For the PN-CCD this can be realized on chip by a deposition of a thin and homogeneous aluminum layer (e.g. 50 nm or 100 nm) on the photon entrance window 10 . The experience to accomplish such thin layers with homogeneous thickness is gained from the fabrication of silicon drift detectors (SDD) in our laboratory.…”

“…They are the main components of the focal plane detectors for the planned X-ray astronomy missions DUO, a NASA satellite, and ROSITA 8,9,10 , a German experiment accommodated on the International Space Station. For ESA's next great X-ray astronomy mission XEUS 11 , the frame store PN-CCD could be the right choice too, as the detector has the capability to meet all the requirements for the wide field imager (WFI).…”

The fully depleted PN-CCD detector is meanwhile field-tested in several experiments on ground and in space. Its application as focal plane detector aboard ESA's XMM-Newton observatory can be considered as the most impressive one. The further development of this detector type including its readout chip in the MPI semiconductor laboratory is presented here. The new device, called frame store PN-CCD, shows substantial improvement of performance, in particular concerning the energy resolution and the probability of out of time event occurrence. Moreover, the detector offers features which are of great importance for its application in space. This is, besides the radiation hardness of the CCD, the variety of feasible pixel sizes and the high frame rates in combination with the small power consumption of the detector. Because of the thin radiation entrance window and the full depletion of the chip, the detector provides a high quantum efficiency for soft X-rays as well as for optical light and the near infrared. The frame store PN-CCD detector will be applied for the proposed X-ray astronomy missions DUO and ROSITA.
