WebThe refractive index (n) and extinction coefficient (k) are related to the interaction between a material and incident light, and are associated with refraction and absorption (respectively). They can be considered as the “fingerprint of the material". ... Example 2: 248 nm photoresist on silicon substrate (PR/Si-Sub) Ex. 2: ... WebNov 12, 2024 · Specifically, a sample of negative tone photoresist was spin-cast onto a silicon wafer (t sample = 750 µm) and exposed to light using a rectangular pattern (pitches of 50 and 100 µm) which produced areas with defined refractive index differences. This sample acts as one mirror in the interferometer setup.
