One of the design concepts currently under study for the vertex detector at the proposed Compact Linear Collider is a High-Voltage CMOS sensor, fabricated in a commercial 180 nm technology, capacitively coupled to a hybrid readout chip. Tests of the assemblies were carried out at the CERN SPS using 120 GeV/c pions, covering incident angles ranging from \(0^{\circ }\) to \(80^{\circ }\). The measurements have shown an excellent tracking performance with an efficiency above 99.7% and a spatial resolution of \(5\,\upmu \hbox {m}\) to \(7\,\upmu \hbox {m}\) over the tested angular range. These results were then compared to TCAD simulations carried out using simulations, showing a good agreement for the current-voltage, breakdown and charge collection properties. The simulations have also been used to optimise future sensor design.
