![]() ![]() The silicon nitride membranes are made by growing a thin silicon nitride film with the desired thickness on a silicon wafer. available in packs of 10 and packs of 25 in a standard TEM grid box.available with standard 200µm and 100µm thick silicon support frame.optimised membrane stress to achieve strength and high planarity.clean, ultra-flat silicon nitride membranes.fully compatible with Ø3.05mm TEM grid holders.sturdy silicon nitride films with 10, 20, 30,50, 100 and 200nm thickness.ideal support for multiple microscopy techniques such as TEM, SEM, FIB, EDX, Auger, XPS and AFM/SPMįeatures of the EM-Tec silicon nitride support films for EM:.high temperature resistant up to 1000° C.high resistance to acids, bases and solvents.amorphous, low background, low scattering material.For special TEM grid holders, a thinner silicon support frame of 100µm is available at a higher price.īenefits of using silicon nitride membranes: The 200µm thickness is compatible with virtually all standard TEM grid holders. The standard silicon frame thickness is 200µm, which provide an easy to handle and sturdy support frame. ![]() The SiN membranes are produced on a 2.65 x 2.65mm die with the back-etched corners to fit the Ø3mm opening in the TEM grid holders. The silicon frame is fully compatible with the standard 3mm TEM grid holders. These support films are manufactured using state-of-the-art MEMS technology to produce debris-free, clean and highly planar membranes. The EM-Tec silicon nitride membranes are stress optimised for each window size and film thickness using proprietary algorithms and chemistry formulations. They are ideal for application such as nano particle imaging, quantitative carbon analysis, chemical experimentation on the support films, real-time chemical reactions and crystal growth research, thin film research, on-film cell growth and multiple microscopy research techniques. The properties of silicon nitride enable producing strong, chemical resistant, carbon-free, low background TEM support films. The EM-Tec silicon nitride membranes are ultra-flat, stress optimised and clean silicon nitride films for TEM applications. ![]()
