Double-metal double-sided silicon microstrip prototype sensors have been developed by Sintef/SI, Micron Semiconductor, and Hamamatsu Photonics for the CDF silicon vertex detector upgrade, SVXII. The ...sensors are biased with polysilicon resistors and have integrated AC-coupling and p-stop isolation. We present measurements of the total capacitance, interstrip capacitance and overlap capacitance due to the double metal structure. The measurements are compared to a simple electrostatic model.
