PELCO® Silicon Nitride Coated and Silicon Ø3mm Discs (blanks)

Silicon Nitride Disks for SEM, FESEM, AFM
Silicon Nitride Blank

 
These 3mm Silicon discs have an ultra-flat (Ra 0.45 ± 0.2nm) 50nm ultra-low-stress Silicon Nitride layer on both sides. Also available with a hydrophilic or hydrophobic surface coating or just as a silicon disk. The disks are made with the same state-of-the-art manufacturing techniques as the PELCO® Silicon Nitride Support Films. The disk are perfectly round and have the Easygrip™ edge for easy handling. Clean surface, no broken edges and free of debris often associated with other manufacturing processes. The ultra-low-stress film is nonstoichiometric and closer to SiN than Si3N4. They can be used for a number of applications:
  • Specimen mounts for SEM and FESEM applications
  • Specimen discs for AFM applications
  • Blanks to build the PELCO® Liquid Cell™ together with the PELCO® Silicon Nitride Membrane
Product Specifications
  • Film Thickness: 50nm ultra-low-stress Silicon Nitride on both sides
  • Hydrophilic: 5nm atomic layer-deposited hydroxylated alumina on 50nm ultra-low-stress silicon nitride More Details
  • Hydrophobic: 5nm atomic layer-deposited alumina and fluoro-methylsilane on ultra-low-stress silicon nitride. More Details
  • Disk Thickness: 200µm silicon support
  • Disk Diameter: 3mm
  • Surface Roughness: The RMS (Rq) is 0.65 +/- 0.06nm which gives a mean roughness (Ra) of 0.45 +/- 0.02nm
  • Packaging: The PELCO® Silicon Nitride Discs with hydrophilic or hydrophobic coating are packaged under cleanroom conditions. The discs are packed in a vial holding 10 discs.

PELCO® Liquid Cell™ Application

silicon nitride coated disk silicon nitride coated disk

Liquid cells have been in use for special microscopy and X-ray analysis techniques and can be used for SEM imaging of liquids, pastes, greases and cells grown on silicon nitride membranes. The material can be applied in the "well" of a Silicon Nitride Membrane Disk or cells can be grown in the well (inside of Silicon Nitride window). To visualize the specimen in the SEM through the membrane the back has to be completely vacuum compatible sealed using the 3mm disk. A second Silicon Nitride membrane can also be used, but the 3mm disk is a more cost effective, sturdier and will keep the liquid better positioned in the "well". Sealing can be done with either a fast curing epoxy glue #14422 or M-Bond® 610 #16039. Make sure the complete Liquid Cell is sealed. To achieve optimum conductivity it is advisable to apply carbon paint on the sides to make a conductive bridge from the Silicon Nitride Membrane disk to the blank. The thin membrane of only 50nm has a low absorbance when using backscatter imaging or EDS in the SEM. The achievable results are similar or better compared to using a polymer type of membrane.





 

PELCO®CLEM Silicon Support Grids with Apertures

 

Silicon Nitride Membrane for CLEM
1 x 1mm 0.75 x 0.75mm 0.5 x 0.5mm 0.25 x 0.25mm 0.5 x 1.5mm 0.1 x 1.5mm 0.1 x 0.1mm

 

The edges of these silicon frames are specially truncated with two parallel flats, which act as an aid for specimen alignment in Correlative Light & Electron Microscopy (CLEM) experiments. These CLEM grids without a silicon nitride membrane are available in a variety of different size apertures and patterns. The CLEM grids are 200µm thick and 3 mm in diameter with two 1 mm-long parallel flat edges on both sides. The grids have a 50nm silicon nitride layer on the back side with bare silicon on the front side. Use of the parallel flats on both sides of the CLEM grid allows the orientation and alignment of the sample to be maintained when using different imaging techniques.
