Square and Rectangular Silicon Nitride Membrane Windows:

NORCADA SiNx membranes offer robust X-Ray and electron transparent sample holders for nanocharacterization and microscopy. The SiNx MEMS devices come with nanometer-thickness membranes tailored to a flexible and optically flat film, and a ridgid silicon support frame. All SiNx membranes are individually inspected to meet Norcada’s high cleanliness and quality standards before cleanroom packaging into gel-capsules to maintain clean, defect free membranes.

These SiNx membranes are optimized for a variety of applications, including:

  • X-ray Microscopy and Spectroscopy
  • Electron Microscopy
  • Optical Microscopy, Interferometry and Raman Spectroscopy
  • Atomic Force Microscopy

Norcada SiNx membranes are usually made with a low-stress (<250MPa) film, which is compatible with a variety of sample-preparation methods including:

  • Thin-film deposition
  • Cell growth and culturing
  • Drop casting and dry powder dispersion of particles
  • 2D materials transfer 
  • Sample annealing and other thermal treatment (Please contact us for processing parameters)
  • Cryogenic sample preparation

Norcada X-Ray SiNx membranes are also offered with both standard and customized features. Our customization can offer the following specification ranges:

  • Membrane stress tailoring from 100MPa to 1000MPa available
  • Membrane thickness from 10.0nm to 6.0µm
  • Membrane sizes from 5µmx5µm to 70mmx70mm, or 20µm to 70mm diameter
  • Frame thickness of 100µm (MX series), 200µm (NX series), 380µm (PX series), 500µm (QX series), and thicker
  • Frame size from 1.0mmx1.0mm to 100.0mmx100.0mm or larger
  • Single-Window or MultiWindow Arrays
