Porous silicon wafers Porous silicon membranes Bragg mirrors Lift-off ready PSi layer Flakes and Powders

Porous silicon wafers

    Production of homogeneous porous silicon (PSi) wafers:

    • micro, meso and macro PSi layer substrates
    • PSi multilayered structures
    • PSi covered surface: 100% or edge excluded
    • Localized PSi wells
    We adjust our processing conditions according to your needs in thickness, porosity and morphology.

Bragg mirror like reflectors

    By controlling the porosity and the thickness of multilayered PSi structures, we can change the PSi surface reflection coefficient in VIS and IR light and produces reflector like Bragg mirrors.
