Latest Patents

Haisheng Song holds a patent titled "Method for detecting flare degree of lens of exposure machine." This patent describes a photomask designed to detect the flare degree of the lens in exposure machines. The photomask features a central exposure area and a peripheral area, where exposure light passes through the lens and penetrates the central exposure area to expose photoresist on a wafer. The central exposure area is equipped with a shading layer to prevent exposure light from penetrating, while the peripheral area contains multiple light-transmitting stripes. This innovative design allows stray light formed after the exposure light passes through the lens to expose the photoresist effectively. The method outlined in the patent enables timely detection and resolution of lens flare issues in exposure machines.
