CRYSTALLINE SILICON MEMBRANES
Norcada Single Crystal (100) Silicon MembraneSingle Crystal (100) Silicon Membrane:
Norcada manufactures single crystal silicon membrane devices for X-Ray diffraction and a range of other applications. Our standard products come with two different membrane thicknesses, 1.0µm and 2.0µm. The membrane is supported by either a 300µm or 380µm thick silicon frame.

Ultrathin Single Crystal (100) Silicon Membrane:
Norcada offers 100nm and 200nm thickness ultrathin single crystal silicon membranes in a standard configuration detailed below. Please note these ultra-thin silicon membranes are slightly wrinkled due to the ultra-low stress and thickness of the membrane film (see photo below). For more details, please contact Norcada.

Flat and Ultrathin Single Crystal (100) Silicon Membrane:
For applications that require thin and flat single crystal silicon membranes, Norcada has developed UberFlat Silicon membranes which are fabricated with support meshes to make the pure silicon membranes flat. The pure silicon membrane is centered on the window area supported by the silicon frame. For more information please contact Norcada.
