Inter-strip capacitance measurments

Line: 30 to 30
  The measurements were done in four different configurations of the bias rail connection:
Changed:
<
<
A Ampere meter and 1 MOhm connected between bias rail and HV return GND plane floating (DC)
B Ampere meter and 1 MOhm connected between bias rail and HV returnGND plane bonded to bias rail
C Bias rail connected directly to HV return
GND plane floating (DC)
D Bias rail connected directly to HV return GND plane bonded to bias rail

The GND plane types are:
bcb
Sensor covered only by BCB layer (6+3 um)
M25 Sensor with meshed GND plane (25 % fill factor and 37 um line width)
solid Sensor solid solid GND plane
bare No BCB and no GND plane: sensors from an old production batch
