Etched Si CDMS-XY
[elementor-template id=”186167″]
Pelcotec™ Etched Si CDMS-XY Critical Dimension Magnification Standard
Easy to use and very useful for quick and precise SEM, FE-SEM, FIB, CD-SEM, LM, and AFM magnification calibration.
Fiducial lines are provided in both X and Y axes for ease of 2 axis calibration without stage rotation.
Available as NIST Traceable or as Certified against NIST Standard
Fully-featured and traceable calibration standards for a wide measurement range. They are made using the latest semiconductor and MEMS manufacturing techniques for etching features yielding superior line edge quality (Line edge roughness of +/- 0.3nm per 1um length of line edge) and are ideal for low keV imaging (≤1keV).
The Pelcotec™ Etched Si CDMS-XY Calibration Standard is available with two feature size ranges, which are both offered as traceable and as certified standards, making a total of 4 unmounted versions:
Pelcotec™ Etched Si CDMS-XY-1T
Fully traceable with features from 2.0mm to 1um for a magnification range from 10x – 20,000x; ideal for desktop SEMs and low to medium magnification applications.
Pelcotec™ Etched Si CDMS-XY-0.1T
Fully traceable with features from 2.0mm to 50nm for a magnification range up to 10x – 200,000x; for all SEM and most FE-SEM applications.
Pelcotec™ Etched Si CDMS-XY-1C
Individually certified against a NIST standard with features from 2.0mm to 1µm for a magnification range from 10x – 20,000x; ideal for desk top SEMs and low to medium magnification applications.
Pelcotec™ Etched Si CDMS-XY-0.1C
Individually certified against a NIST standard with features from 2.0mm to 50nm for a magnification range up to 10x – 200,000x; for all SEM and most FE-SEM applications.
Feature sizes for the Pelcotec™ Etched Si CDMS-XY-1C are:
2mm, 1mm, 0.5mm, 0.1mm, 50µm, 10µm, 5µm, 2µm, and 1µm
Feature sizes for the Pelcotec™ Etched Si CDMS-XY-0.1C are:
2mm, 1mm, 0.5mm, 0.1mm, 50µm 10µm, 5µm, 2µm, 1µm, 500nm, 250nm, 100nm, and 50nm

500nm, 250nm, 100nm and 50nm lines are only on the Etched Si CDMS-XY- 0.1T and 0.1C products
The Pelcotec™ Etched Si CDMS-XY Critical Dimensions and Magnification Standards are made on an ultra flat silicon substrate with a precision etched lines for features sets from 100nm to 2µm. Due to its sturdy construction, the CDMS-XY Standard can be cleaned using a plasma cleaner on low settings.
The smaller features are nested for easy navigation and quick calibration. The accuracy of the features is 0.3% or better. The actual size of the standard is 2.5 x 2.5mm with a thickness of 525µm ±10µm. There is no coating on the Si surface. Each Pelcotec™ Etched Si CDMS-XY Calibration Standard has a unique identification number.
They are available either unmounted or mounted on SEM holders A-R. For AFM applications the Pelcotec™ Etched Si CDMS-XY is mounted on a 12mm AFM disc; for LM applications it is mounted on a 25 x 75mm glass slide.
The Etched Si CDMS-XY Standard may also be mounted on a custom mount of your choice.
Store the Pelcotec™ Etched Si CDMS-XY Calibration Standard in a vacuum desiccator such as the PELCO® SEM Sample Stub Vacuum Desiccator.
