The inner detector of the ATLAS experiment will contain three layers o
f pixel detectors. The prototype of the sensor part is an n(+)n-device
in order to allow partial depleted operation after bulk inversion and
a guard-ring scheme keeping the entire detector surface close to the
electronic chip on ground potential. Further, a bias structure is intr
oduced providing testability of the sensors before mounting them to th
e electronics. The design of the single pixel cell is the result of a
detailed device simulation study. (C) 1998 Elsevier Science B,V. All r
