A Photolithography Process Design for 5 nm Logic Process Flow
With the introduction of EUV lithography, the photolithographic process in 5 nm logic process can be simplified to use mostly single exposure method. In a typical 5 nm logic process, the contact-poly pitch (CPP) is 44-50 nm, the minimum metal pitch (MPP)

A 1 × 2 Two-Dimensional Slanted Grating Based on Double-Layer Cylindrical Structure
Diffraction gratings play an increasingly important role in various planar optical systems, such as near-eye display systems for virtual reality (VR) and augmented reality (AR). The slanted gratings have more advantages than other elements.
