Pelcotec™ CDMS & Pelcotec™ CDMS-XY
Critical Dimension Magnification Standards

Available as NIST Traceable or as Certified against NIST Standard

Easy to use and very useful for quick and precise SEM, FESEM, FIB, CD-SEM, LM, and AFM magnification calibration.

Unique, economically priced, yet fully featured and traceable calibration standards for a wide measurement range. They are made using the latest semiconductor and MEMS manufacturing techniques.

Feature sizes for the Pelcotec™ CDMS-1T and -1C are: 
2mm, 1mm, 0.5mm, 0.25mm, 10µm, 5µm, 2µm and 1µm

Feature sizes for the Pelcotec™ CDMS-0.1T & 0.1C are: 
2mm, 1mm, 0.5mm, 0.25mm, 10µm, 5µm, 2µm, 1µm, 500nm, 250nm and 100nm.

The Pelcotec™ CDMS Critical Dimensions and Magnification Standards are made on an ultra flat silicon substrate with a precise 50nm chromium deposition for the features up to 5µm and a combination of 50nm gold over 20nm chromium for the features sizes from 2µm to 100nm. The Cr and Au/Cr on Si provides excellent contrast both in SE and BSE imaging mode. The features are easier to determine than on etched Si standards. Since the silicon substrate, the chromium and the chromium/gold features are all conductive there are no charging issues with this calibration standard. Due to its sturdy construction the CDMS standard can be cleaned using a plasma cleaner. 

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 675µm ±10µm. There is no coating on the Si surface. Each Pelcotec™ CDMS calibration standard has a unique identification number.

They are available either unmounted or mounted on SEM holders A-R. For AFM applications the Pelcotec™ CDMS is mounted on a 12mm AFM disc, for LM applications it is mounted on a 25 x 75mm glass slide. 

The specimen may also be prepared on a custom mount of your choice.

Store the Pelcotec™ CDMS Calibration Standard in a vacuum desiccator such as the PELCO® SEM Sample Stub Vacuum Desiccator.
