Pixel arrays #1 - to #14 have metal only on top of the pad, while the pixels from arrays #15 - #32 are totally covered in metal. In principal this shouldn't change the breakdown voltage, but we are seeing that #15 -#32 show a higher breakdown voltage. It can also be seen that we are using different p-stop designs for the pixels, the effect of those remain to be checked. We are currently collecting more data so that we can get statistics on the p-stop designs.
