SILICON NITRIDE TEM WINDOW GRIDS
5 nm, 10 nm, 20 nm, 50 nm, and MICROPOROUS
Silicon Nitride (SiN) TEM Windows for TEAM
Low-Stress Silicon Nitride (NOW MORE CONDUCTIVE)
– 100 micron thick frame – fits the sample holder of the TEAMi Microscope.
– 5 nm thick Silicon Nitride film
– (2) 50 x 450 micron windows
We have co-developed a novel conductive coating with the National Senter for Electron Microscopy at Lawrence Berkeley National Laboratory for our two-slot 5 nm silicon nitride film using a premium high-temperature ultrathin carbon coating. The benefits include:
– Efficient charge dissipation for minimal sample charging
– High resolution, high stability imaging
– Clean, consistent and low-contrast background
– Superior image quality even at high tilt
We’ve also reduced the width of the slots to 50 microns. This makes slots more robust during sample preparation while also reducing the incidence of vibration during imaging. Low vibration is particularly important for tomography and high-tilt applications.
Note: It has been reported that the 5 nm silicon nitride windows may have slight wrinkling (significantly less than silicon dioxide or pure silicon). This does not affect TEM imaging.
Improved Grid Shape
We have re-engineered our TEM grids so that they are easier to handle. By making the grids slightly narrower users now have easy access to grids in TEM holders. No more fumbling with tweezers while trying to pick up or put down grids. The new TEMWindow grid shape is still compatible with all standard holders.

– Competitively Priced: state of the art manufacturing processes and an expert engineering team allow us to offer Silicon Nitride solutions at competitive prices
– Plasma Cleanable: Silicon nitride grids can be vigorously plasma cleaned to remove organic contamination, unlike carbon grids
– Increased Uniformity: reduced field-to-field variability
– Tolerates temperatures >1000C: supports use in environmental TEMs where dynamic processes are observed at high temperatures
– Withstands harsh deposition & chemical conditions: provides an ideal balance of imaging resolution and mechanical strength
– Incorporates LPCVD, low-stress (~250MPa), non-stoichiometric silicon nitride: provides flat, insulating and hydrophobic surfaces
