WebElectron beam lithography (EBL or e-beam lithography) is the technique that can be used to create the smallest features (as small as 5 nm).³ Rather than using light to illuminate the surface, a tightly focused beam of electrons is scanned over the surface. The electron beam exposes the pattern and then the resist can be developed. After this, the pattern transfer … Web5 jan. 2024 · PPT - Soft Lithography PowerPoint Presentation, free download - ID:9616944 Create Presentation Download Presentation Download 1 / 19 Soft Lithography 41 …
