Lithography wavelength
Web8 dec. 2024 · Since most lithography systems emit polychromic light with peaks of 365 nm, 405 nm, and 436 nm, diffraction from different wavelengths with a long exposure may cause a crosslinking of SU-8, producing an unwanted sidewall profile as described in Fig. 1. An SU-8 array with 2-mm height was fabricated using typical lithography as shown in Fig. 2. WebThe W 2D PhC was fabricated by a simple nano-imprint lithography (NIL) process, and inductive coupled plasma reactive ion etching (ICP-RIE) with an isotropic etching process, the benefits and parameters of which are presented. The fabricated W PhC emitter showed spectrally selective emission near the infrared wavelength range, ...
