The Keysight 4881HV is a specialized high-voltage (HV) wafer-level test system designed to address the testing needs of high-voltage semiconductor devices—such as power management ICs (PMICs), discrete power components (e.g., MOSFETs, IGBTs), and high-voltage sensors—during wafer fabrication and characterization phases. It integrates precise high-voltage sourcing, measurement capabilities, and wafer-handling compatibility to enable efficient, reliable testing of devices operating at elevated voltage levels, while ensuring accuracy and compliance with industry standards.

Core Application Focus

The system is tailored for testing high-voltage semiconductor devices across multiple stages of the production and R&D workflow, including:

Wafer-level characterization: Validating electrical performance (e.g., breakdown voltage, leakage current) of devices before dicing.
Production testing: High-throughput screening of wafers to identify defective devices early, reducing post-assembly costs.
R&D for high-voltage technologies: Supporting design validation of next-gen power devices (e.g., for automotive, industrial, or renewable energy applications) that require operation at 100V to 1000V+ levels.

Key Technical Capabilities

High-Voltage Sourcing & Measurement: Supports sourcing and measuring voltages up to 1000V DC with low noise and high stability.
Current Measurement: Sensitive current detection down to nA or µA ranges to measure leakage currents.
Compliance Protection: Built-in overvoltage (OVP) and overcurrent (OCP) protection.
Wafer Compatibility: Works with standard 6-inch, 8-inch, and 12-inch wafers and automated probers.
Probe Card Integration: Supports high-voltage probe cards (e.g., Kelvin probes) for stable electrical contact.
Automation & Software: Integrates with test software (e.g., PathWave Test Executive, VEE Pro) for test sequencing and data logging.

System Architecture

High-Voltage Source/Measure Unit (SMU): Core module for sourcing HV and measuring device responses.
Wafer Prober Interface: Enables communication with automated probers to position wafers.
Control Unit: Manages test sequences, hardware synchronization, and data processing.
