A new type of n-in-p planar pixel sensors have been developed at KEK/HPK in order to cope with the maximum particle fluence of 1-3×1016 1 MeV equivalent neutrons per square centimeter (neq/cm2) in the upcoming LHC upgrades. Four n-in-p devices were connected by bump-bonding to the new ATLAS Pixel front-end chip (FE-I4A) and characterized before and after the irradiation to 2×1015neq/cm2. These planar sensors are View the MathML source thick, using biasing structures made out of polysilicon or punch-through dot and isolation structures of common or individual p-stop. Results of measurements with radioactive 90Sr source and with a 120 GeV/c momentum pion beam at t...
