Abstract
A transmission electron microscope high-resolution in situ fluid freezing chip includes a lower chip and an upper chip. The lower chip is provided with a support layer, a freezing layer, an insulating layer, an opening, and a center window. The freezing layer is provided with contact electrodes, semiconductor films, and a conductive metal film. The center window is surrounded by the conductive metal film; the contact electrodes are disposed at an edge of the chip. One ends of the semiconductor films are lapped on the conductive metal film, and the other ends are lapped on the electrodes. In the outer edge of the conductive metal film, silicon is etched to form the opening. The support layer covers the opening. The conductive metal film is disposed on the support layer. A plurality of holes are provided in the center window.
