| 1. An apparatus comprising:
a sample holder for a scanning electron microscope having an electrical interconnect and leads on top of the sample holder
electrically connected to the electrical interconnect, the sample mounted on the sample holder comprising a plurality of electrodes,
the sample holder comprising wire bonds connecting the leads to the plurality of electrodes;
a power source and a controller connected to the electrical interconnect for applying voltage to the sample holder to control
the secondary electron emission from a sample mounted on the sample holder; and
a computer coupled to a secondary electron detector to generate images of the secondary electron emission from the sample.
