Abstract
During the high luminosity phase of the LHC starting around 2020 (HL-LHC), the machine is expected to deliver an instantaneous luminosity of $5 \cdot 10^{34}\ \tt{cm}^{-2} s^{-1}$. A total of $3000\ {\tt fb}^{-1}$ of data is foreseen to be delivered, hereby increasing the discovery potential of the LHC experiments significantly. However, the radiation dose of the inner tracking systems will be severe, requiring new radiation hard sensors for the CMS tracker. Up to now, typically p-in-n float zone devices with a thickness of at least 300 micrometers have been used for silicon strip detectors at CMS and other experiments. However, the signal-to-noise ratio for sen...
