Abstract
CMS started a campaign to identify the future silicon sensor technology baseline of the new tracker for the high-luminosity phase of LHC. We ordered a large variety of 6 inch wafers in different thicknesses and technologies at producer Hamamatsu. Thicknesses ranging from 50 microns to 300 microns are explored on Floatzone, Magnetic Czochralski and Epitaxial Silicon both in n-in-p and p-in-n versions. P-stop and p-spray are explored as isolation technologies for the n-in-p type sensors as well as the feasibility of double metal routing on 6 inch wafers. Each wafer contains many different structures to answer different questions, e.g. geometry, Lorentz angle, radi...
