Resistivity Reference Wafer : NRW Series
DESCRIPTION: NRW series are resistivity reference wafers which are calibrated and tracable for Napson’s resistivity measurement systems. NRW series use neutron irradiatiated wafers for excellent stability.APPLICATIONS: Napson’s four-probe resistivity measurement systems are calibrated by standard wafers (NIST, VLSI), and conform to the standards stipulated by SEMI standards, Japanese Industrial Standards (JIS) and American Materials Testing Association (ASTM).
