Description

Protection of AC coupling capacitors from beam splashes has been studied on the heavy irradiated HPK ATLAS07 mini-sensors with special structures, BZ4A,B,C and D, for p-stop ion concentrations 2e12, 4e12 and 1e13 ion/cm^2. Punch through voltage is rapidly increasing with neutron fluence from 4e14 neq/cm^2 to 2e15neq/cm^2 for all tested ion concentrations and for 1E13 ion/cm^2 it is significantly higher than 50V. Measurement prefers PT structure BZ4A and ion concentration ~4E12 ion/cm^2.
