WebNov 14, 2024 · In this Letter, we demonstrate a centimeter-scale, all-glass metalens capable of focusing and imaging at visible wavelength, using deep-ultraviolet (DUV) projection stepper lithography. Here, we show size-scalability and potential for mass-production by fabricating 45 metalenses of 1 cm diameter on a 4 in. fused-silica wafer. WebSoft lithography is a general term used to describe high-resolution (features less than 25 μm) patterning methods that involve elastomer masks, stamps, and molds (Xia and Whitesides 1998). The masks, stamps, and molds are fabricated by casting and curing a prepolymer of polydimethylsiloxane (PDMS) against a patterned photoresist.
