Latest Patents

Yayi Wei's latest patents include a method for manufacturing semiconductor devices. This method involves forming a photolithographic coating on a to-be-connected structure, which includes a first film, a photolithographic film, and a second film. The refractive indexes of the first and second films are smaller than 1. The coating is exposed to light of a first wavelength to image the structure to a first region of the photolithographic film. It is then exposed to light of a second wavelength through a mask to image the mask to a second region of the photolithographic film. The overlap of these regions creates a connection region, facilitating self-alignment between layers.

Another notable patent is a method and device for optimizing mask parameters. This method includes acquiring a test pattern, light source parameters, and initial mask parameters. It generates multiple sets of candidate mask parameters based on the initial mask sidewall angle. By simulating these parameters, the optimal mask sidewall angle is determined, significantly improving imaging contrast and resolution.
