Tesla: On-Wafer Power Device Characterization System

Tesla solves the challenge of thin wafers, power dissipation and current/voltage requirements

Tesla: On-Wafer Power Device Characterization System

The broad use of power semiconductors has created a pressing need to characterize power devices quickly and efficiently. Cascade Microtech’s new Tesla on-wafer power device characterization system meets the challenge, reducing time-to-market for new power devices. Tesla is the industry’s first power device measurement system that provides a complete on-wafer solution for over-temperature, low-contact resistance measurements of power semiconductors up to 60A and 3000V. The new system features two new wafer probes and a brand new wafer chuck technology.
  • The High Current Parametric (HCP) probe is designed to meet the needs of Rds(on) measurements.  A unique design minimizes thermal runaway at the probe to wafer contact while supporting up to 10A of current in continuous mode and up to 60A of current in pulsed mode.
  • The High Voltage Parametric (HVP) probe enables breakdown voltage measurements as low as 1pA at 3000V.
  • Exclusive Vacuchannel™ chuck technology meets the needs for today’s power device wafers with state-of-the-art handling for thin wafers as thin as 100um.  In addition, the Vacuchannel technology handles power dissipating devices like no other solution available today enabling on-wafer measurements for devices up to 75W.
