Patent ID: 8058627

Claim:
A transmission electron microscope grid comprising: a substantially planar substrate adapted to fit within a stage of a transmission electron microscope, the substrate providing: a first insulating layer providing a plurality of peripheral apertures through the first insulating layer at a periphery of the substrate; a coplanar conductive layer attached to a rear surface of the first insulating layer to be coplanar with the first insulating layer and patterned to provide multiple electrically isolated conductors leading from the peripheral apertures to a central experimentation region of the substrate within the periphery of the substrate; conductive pads exposed at a front surface of the first insulating layer and passing through the peripheral apertures to electrically contact the electrically isolated conductors; and central apertures in the central experimentation region passing through the first insulating layer to selectively expose the multiple electrically isolated conductors at the central experimentation region.
