High quality custom designed chips, send your request to request@SPRchips.com
Substrates: We make sure that you get exactly the substrate that you want. In stock: Si, Fused silica, Borofloat, NBK7, D263T
Layers: Most materials are available (Au, Ag, Al, Al2O3, C, Cr, Cu, Fe, Ge, Hf, Mg, Nb, Ni, NiCr, Pr, Pt, Si, SiO2, Si3N4, Ta, Ti, TiN, TiO2).
Evaporation or sputtering is normally used to apply the films.
Patterns: Photolithography or EBL are used to transfer patterns. Minimum feature size 30nm
