The TESLA300 Advanced On-Wafer Power Semiconductor Probe System is an integrated high-power test solution that enables collection of accurate high-voltage and high-current measurement data up to 3 kV (triaxial) / 10 kV (coaxial) and 200 A (standard) / 600 A (high current), with complete operator safety.
The TESLA300 provides lab automation capabilities and enables high-power electrical measurements for device characterization, high-volume engineering and extremely challenging applications. It is also ideally suited in customized solutions, niche production applications, and emerging markets.
Patented AttoGuard technology built in TESLA300 significantly improves low-leakage and low-capacitance measurements. In combination with FormFactor’s patented TESLA FemtoGuard™ thermal chuck technology, the TESLA300 provides a fully guarded and shielded test environment. The high-power TESLA FemtoGuard chuck also incorporates MicroVac™ technology enabling low-contact resistance, thin wafer handling and maximum power dissipation.
