By use of extensive simulation, it is shown how a spread of the alumin
ium metallization over the intercathodic field oxide sensibly lowers t
he electric field at reverse biased p(+) n junctions, thus allowing us
e of higher drift fields. Based on the simulation results, the layout
of a few test structures implementing alternative technological choice
s has been defined. The fabrication of these prototype detectors is pr
esently in progress.
