These PELCO Membranes of Silicon Dioxide (SiO2) offer superior flatness. Using advanced MEMS manufacturing technologies combined with novel stress-reducing techniques, we have been able to provide Silicon Dioxide Support Films with unsurpassed flatness and a membrane thickness of 40nm, 18nm and 8nm. It is truly the next generation Silicon Dioxide membranes. The flatness of our silicon dioxide membranes is at least 10x better than competitive products. The SiO2 membranes are completely amorphous.

The Silicon Dioxide (SiO2) Support Films are manufactured using the PELCO 200nm Silicon Nitride (Si3N4) Support Films with the 0.5 x 0.5mm window on a perfectly round 3mm Si frame as a platform. The silicon dioxide support films consist of pure and amorphous thermal SiO2 membrane. The 0.5 x 0.5mm membrane is patterned into 24 ea. apertures with a size varying between 50 x 50µm to 70 x 70µm and etched back to the thermally-deposited amporhous Silicon Dioxide leaving a structure-free SiO2 thin membrane of 40nm, 18nm or 8nm, suspended by a 200nm optically transparent (Si3N4) support mesh. The bar size between the SiO2 apertures is 25-35µm and the boundary width is 25-55µm. The design of the mesh and the ratio of mesh suspension and Silicon Dioxide Film has been optimized to enable flat Silicon Dioxide Support Films with a size of 50 x 50um to 70 x 70um. The result is a Silicon Dioxide membrane with a truly superior flatness, ideal for TEM imaging. In the unique design of this PELCO product, the compression in the SiO2 film is balanced by the stress in the Si3N4 grid structure. The mesh size of the Silicon Dioxide Support Films is comparable to the area size found on most 300 and 400 mesh TEM grids and is considered to be a practical size for many applications. There are 24 fields of SiO2 support films on each frame. The boundary of 200nm Si3N4 membrane leaves ample area for experiments on Si3N4. 

Thermal Silicon Dioxide is one of most functionalised surfaces in analytical chemistry and can be used as a platform to study base materials and biological entities. The support films can be either used as a passive physical support for TEM imaging or as an active participant in experiments. The PELCO Silicon Dioxide Support Films have excellent chemical, physical and thermal stability. Properties can be modified or enhanced by coatings, or properties of thin films can be studied by direct deposition on the Silicon Dioxide Film. The 8nm thin SiO2 membranes are resilient enough to allow for manufacturing custom made holes by using an FIB.

Examples of applications are: 

  • Nanomaterial deposition and growth.
  • Thin film analysis and characterisation.
  • Catalyst research and development.
  • Support for FIB lamellae.
  • Characterisation of semiconductor materials.
  • Study of attached biological molecules.

Product specifications

Defining parameters for the PELCO Amorphous Silicon Dioxide Support Films are:

  • Membrane Thickness: 40nm, 18nm and 8nm.
  • Aperture Size / Number: 50 x 50µm/24 apertures for 40nm, 60 x 60µm/24 apertures for 18nm and 70 x 70µm/24 apertures for 8nm.
  • Pattern: 5 rows x 5 columns with 200nm Si3N4 grid support structure, 35µm bar and 55µm edge for 40nm, 35µm bar and 30µm edge for 18nm and 25µm bar and 25µm edge for 8nm..
  • Total Window Area: 0.5 x 0.5mm.
  • Frame Thickness: Silicon support structure is 200µm standard. This allows for fitting in standard TEM holders and gives a sturdy support frame.
  • Surface Roughness: The RMS (Rq) is 0.65nm which gives a mean roughness (Ra) of 0.41nm.
  • Frame Diameter: TEM standard 3mm diameter disc, fully compatible with regular TEM holders and with EasyGrip edges for improved handling.
  • Packaging: The PELCO Silicon Dioxide Support Films are packaged under cleanroom conditions in the PELCO TEM Grid Storage Box. Each box holds 10 support films.
