March 2, 2009: Norcada Inc., a MEMS design and product development company, has announced the availability of a new TEM (transmission electron microscope) nitride window array device to the TEM research community.
The new TEM window array devices enable the end users to conduct multiple analyses in-situ on a single TEM nitride membrane device, which increases the throughput significantly, Norcada announced in a news release.
The TA301 series TEM nitride window array device has nine individual membrane windows in a 3×3 array pattern on a single 200μm-thick octagon-shaped silicon frame, which fits inside a 3mm diameter circle. Each silicon nitride window of the 3×3 array is 100μm × 100μm in size, and the spacing between two adjacent windows is 350μm (edge to edge).
The initial devices being offered have a 100nm thickness low-stress silicon nitride membrane (part number TA301C). Additional TEM devices with 30nm and 50nm thickness silicon nitride membranes will become available shortly.
