    Abstract: PROBLEM TO BE SOLVED: To electrically ground a substrate through an insulating layer on a surface of the substrate by nondestructive method.SOLUTION: It relates to a device for forming a conductive passage through an insulating layer on a surface of a substrate. A first radiation source is arranged so as to emit radiation to a first region of the insulating layer and a first electric contact is arranged so as to apply a first bias voltage to the first region. A second radiation source is arranged so as to emit radiation to a second region of the insulating layer and a second electric contact is arranged so as to apply a second bias voltage to the second region. Conductivity of the regions is increased by radiation such that a conduction passage is formed through the insulating layer in the regions. In an embodiment, the device can be used in an electron beam apparatus. Another embodiment relates to a method for forming the conductive passage through the insulating layer.
