SILICON NITRIDE WINDOWS FOR X-RAY MICROSCOPY

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
