Since 1994, Silson Ltd had been supplying ultra-thin membranes and related lithographic products to Corporations, Universities and Government Research Laboratories throughout the world. Products are extensively used within the x-ray and e-beam communities but additionally Silson is now able to offer a MEMS prototyping service.


Standard silicon nitride membrane windows

The standard range of Silson silicon nitride membrane windows consist of square silicon nitride membranes in square silicon supporting frames. The standard frame sizes are: 5.0, 7.5 and 10.0 mm.

The default frame thickness is 200 µm but we are also able to offer the full range of membrane thicknesses on 381, 525 and now 100 µm thick substrate stock. The standard membrane sizes are: 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0 and 5.0 mm

The maximum membrane size within a 5.0 mm frame is 1.5 mm and the maximum for a 7.5 mm frame is 3.0 mm. Otherwise, the full range of membrane sizes is available within each of the standard frame sizes. The following range of standard membrane thicknesses is available: 30, 50, 75, 100, 150, 200, 500 and
1000 nm.

If your preferred design is not covered by the above permutations then we may able to help you with one of our other products.

Use the standard product finder to see if your preferred permutation is available.
