NEW Pelcotec™ CDMS ISO 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 in the X axis.

Available in two feature size ranges and as traceable at the wafer level to a NIST standard (ISO 17025:2017 Sampling Scope of Accreditation) or individually certified to a NIST standard in an ISO 17205:2017 accredited calibration laboratory, for a total of four versions:

Pelcotec™ CDMS-1T-ISO
Fully traceable at the wafer level to a NIST standard (ISO 17025:2017 Sampling Scope of Accreditation). Has features from 2.0mm to 1um for a magnification range from 10x - 20,000x; ideal for desktop SEMs and low to medium magnification applications.

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

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

The Pelcotec™ CDMS ISO 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 from 2µm to 100nm. The Cr and Au/Cr on Si provide 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 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™ CDMS ISO 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 ISO is mounted on a 12mm AFM disc; for LM applications it is mounted on a 25 x 75mm glass slide.

The CDMS standard may also be mounted on a custom mount of your choice.

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

500nm, 250nm and 100nm lines are only on the CDMS-0.1T-ISO and CDMS-0.1C-ISO product families
