LIQUID CHIP FOR ELECTRON MICROSCOPE INCLUDING ELECTRODE

Abstract

The present disclosure relates to a liquid chip for an electron microscope including a lower chip, an upper chip, and a waterway space part for supplying a liquid sample, and may attach a transmissive thin film layer made of a graphene material having an excellent bulging resistance property to a plurality of holes formed in a waterway space part to increase the thickness of a support not operating as a transmissive window to be larger than the conventional one, thereby supplying the liquid sample more stably and minimizing the loss of a spatial resolution and also suppressing the bulging phenomenon of the transmissive window. To this end, according to the present disclosure, the lower chip includes a lower substrate formed with a lower cavity; a lower support disposed on the upper surface of the lower substrate, and formed with a plurality of lower holes in the lower cavity region; a spacer located on both ends of the lower support of the lower hole; and a lower transmissive thin film layer attached on the lower support so as to cover the lower hole, the upper chip includes an upper substrate formed with an upper cavity; an upper support disposed on the upper surface of the upper substrate, and formed with a plurality of upper holes in the upper cavity region; and an upper transmissive thin film layer having a constant bulging resistance property attached on the upper support so as to cover the plurality of upper holes, the waterway space part is formed by laminating the upper support disposed on the upper surface of the upper substrate on the spacer of the lower chip, and the transmissive thin film layer is located inside the waterway space part.
