MF153000 - SEMI MF1530 - Test Method for Measuring Flatness, Thickness, and Total Thickness Variation on Silicon Wafers by Automated Noncontact Scanning Revision:SEMI MF1530-0707 - Superseded An eddy-current instrument directly measures

An eddy-current instrument directly measures conductance of a specimen

Although existing factories can be retrofitted to implement water reuse

The specific purpose of this Specification is to describe a network-independent application model comprised of device objects which are common to all vacuum pump devices (VPD) on a semiconductor equipment Sensor/Actuator Communications Network
