  • Patent number: 11104043
    Abstract: A thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon. Preparing thermal extrusion mold: the through-hole arrays with 0.8˜1.25 mm diameter, 0.25 mm interval space and 0.6˜1.0 mm height are first obtained on metals, and are then polished, rinsed and dried. Thermal extrusion: polymer materials are first thermally extruded on the obtained mold and cooled to room temperature. Demold: excess polymer materials flowing from the through hole are cut off and then the polymer cylinder pillar arrays are lifted off from the mold. Superhydrophobic treatment: the whole polymer sample is treated using mixed liquid spray consisting of titanium oxide nanoparticles dispersed in fluoroalkylsilane ethanol solution, and the superhydrophobic cylinder pillar arrays are obtained.

  • Patent number: 11043448
    Abstract: A semiconductor device and a manufacturing method thereof are disclosed. In which a first opening and a second opening are vertically separated, and are no longer restricted by the condition that a deep upper opening needs to be filled with a thick photoresist when a TSV nested hole in vertical communication forms a middle opening and lower opening, thereby satisfying devices with different thicknesses requirements. The design is no longer restricted by the lateral process of the TSV nested hole, thereby enhancing the flexibility of the design. In the photolithography process, the deep hole does not need to be filled with the photoresist, the photoresist does not need to be thick, thereby reducing the complexity of the photolithography process and improving the exposure effect. The first metal layer and the second metal layer are directly led out via a first trench, thereby simplifying the process and reducing the production cost.

  • Patent number: 10943853
    Abstract: A semiconductor device and a manufacturing method thereof are disclosed. In the device, the isolation layer is used to prevent the first metal layer and the second metal layer which are over-etched and back-splashed from diffusing to a first substrate; and the isolation layer serves as a barrier layer to prevent an interconnection layer from diffusing into the first substrate. Further, the isolation layer includes a silicon nitride layer, which is advantageous for preventing the metal layers from back-splashing and diffusing to the sidewall of the first substrate. The isolation layer further includes a first silicon oxide layer and a second silicon oxide layer, wherein the second silicon oxide layer is used to protect the silicon nitride layer from being etched and consumed and the first silicon oxide layer is used to improve the adhesion between the silicon nitride layer and the first substrate.
