The ATLAS upgrade for HL-LHC operation includes the installation of an entirely new all-silicon Inner Tracker (ITk). The silicon strip region comprises 165,mathrm{m}^2165m 2 of instrumented area, made possible by mass production of silicon strip sensors. This area is covered in a nearly hermetic way. Multiple sensor shapes are utilized: square sensors in the barrel part, and skewed trapezoidal sensors with curved edges to provide a continuous coverage of the disc surface in the endcap part of a detector. As a result, there are 88 different strip sensor types in the system. They all feature AC-coupled n{}^+ + -in-p strips with polysilicon biasing, developed to withstand the total fluence of 1.6cdot 10^{15},mathrm{n_{eq}/cm^2}1.6⋅10 15 n eq /cm 2 and the total ionizing dose of 66, mathrm{Mrad}66Mrad.
