Pelcotec™ SFG12 Finder Grid Substrate
The innovative Pelcotec™ SFG12 finder grid substrate is a flat, conductive silicon substrate with a die size of 12.5 x 12.5mm. It is covered with a 1 x 1mm raster giving a total of 12x12=144 fields. Each field has a unique label using an alphanumeric pattern. The lines and labels are precision laser etched in the silicon surface. It is the best combination of a flat specimen support and an SEM finder grid.
This unique and innovative product has some resemblance with an engraved SEM specimen mount, but it has a number of additional advantages:
-
Flat - there are no height differences like with copper finder grids
-
Fine pattern over a large area - better defined than engraved SEM mounts
-
Low background signal - same as with Si chip substrates
-
For EDX analysis only one element (Si) from the finder substrate
-
Practical and easy to navigate - 1mm spacing with 144 fields
-
Pattern is visible with naked eye, preparation microscope and SEM
-
Gives an approximate size at (very) low magnification
-
Can easily be mounted on SEM sample stubs - compatible with most popular sizes
-
Can be used with SEM, FIB, XPS/ESCA, Auger and LM
Specifications of the silicon substrate used: prime virgin silicon wafer, P Boron doped, <100> orientation, resistivity of 0.5-35 ohm/cm, thickness 645 µm ±55µm.
