Silicon Nitride film window of SHNTI is the most cost-effective
products, its applications is very wide. It could use for analysis like
TEM、X-Ray、SEM and so on.It can completely avoid the background of carbon when it be used at TEM analysis.
nitride film window used in the X-Ray can be achieved maximum
transmission rate of soft X-ray (such as vacuum ultraviolet). The softer
X-ray, the lower energy ，the
worse penetrating it could have, so that it required thinner silicon
nitride window. Especially in the “off-axis” work module (i.e. film and
beam at a certain angle),we also need thinner film window, and better
measurement of existing technology or ST Silicon nitride film, although
it has a high residual stress to the ST film, they are not strong
enough, and easy to break. Based on the needs of X-ray microscopy and
transmission imaging, Silicon nitride film on the soft X-ray must
satisfy the smaller absorption. The Silicon nitride film windows
supplied by SHNTI are low stress load tools (also available as
mini-dish, support film), that improved the shortcomings of the original
acteristics Silicon nitride film windows of SHNTI:
estimating the transmission performance of the film, the absorption
line should be noticed, if it’s necessary to consider the optical
properties, absorption limit should be lower than 13nm. When the
absorption limit is 13nm,100nm thick film transmittance is 44%; When the
absorption limit is 2.4nm, the light transmission decline to 13%.
nitride film window film is smooth, strength, density is good, very
stable surface smoothness (roughness less than 1nm). Normally there’s no
negative effect for the application. We can see that the surface of
silicon nitride thin film situation by the AFM testing.
products can be used in high temperature areas, it is able to withstand
1000 degree centigrade heating, It’s very suitable for the surface of a
silicon wafer substrates grown by CVD using a variety of nano-materials.
No reaction with other inorganic acids , except HF.
SHNTI silicon nitride film window does not have the hydrophilic nature itself,
