This invention proposes a nano-transparent semiconductor electrothermal structure, its fabrication method, and a semiconductor electrothermal module. The nano-transparent semiconductor electrothermal structure comprises, from bottom to top, a first insulating layer, a substrate, an electrothermal layer, a second insulating layer, and electrodes. Both the first and second insulating layers are nanoscale insulating films formed by pulsed radio frequency synergistic physical vapor deposition of hexagonal boron nitride. The first insulating layer is formed on the back side of the substrate, and the second insulating layer is formed above the electrothermal layer. The electrothermal layer is a nanoscale electrothermal conversion film formed by aluminum-doped zinc oxide, tin-doped indium oxide, and fluorine-doped tin oxide containing yttrium trioxide. At least one of tantalum, beryllium, and niobium is embedded in the lattice gaps of the electrothermal layer. The electrothermal layer is used for electrothermal conversion when energized. Electrodes are disposed on both sides of the electrothermal layer, and the electrodes are in contact with the electrothermal layer and connected to a power source. This invention adds a first insulating layer to the back of the substrate, which, together with the second insulating layer above the heating layer, forms a double-sided hexagonal boron nitride insulating protection structure. This effectively blocks leakage paths on the back of the substrate, improving safety. At the same time, the double-sided high thermal conductivity insulating layers balance the thermal resistance on both sides of the substrate, improving heating uniformity. The two equal-thickness thin films ensure symmetrical stress on both sides of the substrate, preventing warping and deformation. The heating layer uses pulsed radio frequency synergistic physical vapor deposition to improve film uniformity. Moreover, the use of hybrid deposition reduces the indium content while still achieving a better-performing heating layer.
