What it is

The Cascade Microtech EPS150TRIAX is a manual probe station for low-noise probing and measurement on small features and wafers. The EPS150TRIAX is a triaxial probing solution for 150 mm manual probing.[1][3][4]

How it works

The EPS150TRIAX uses a triaxial signal path down to the device under test to support low-noise measurements. The EPS150TRIAX uses a vacuum chuck, magnetic-base micropositioners, and x, y, and z movement for probe placement.[1][2]

The EPS150TRIAX includes a trinocular stereo zoom microscope for visual alignment. The EPS150TRIAX supports current, voltage, resistance, capacitance, conductance, sheet resistance, and resistivity measurements through attached measurement instruments.[1][2]

Where it fits in the process flow

The EPS150TRIAX fits in wafer-level and package-level electrical test workflows. The EPS150TRIAX is used for I-V characterization, C-V characterization, low current measurements, resistance and conductance measurements, and sheet resistance and resistivity measurements.[1]

Applications

The EPS150TRIAX supports low-current I-V measurements. The EPS150TRIAX supports C-V characterization over a frequency range from 20 Hz to 1 MHz.[1]

The EPS150TRIAX supports sheet resistance and resistivity measurements of substrates and thin films. The EPS150TRIAX also supports capacitance and conductance measurements.[1]
