Keysight Technologies, Inc. (NYSE: KEYS) expands its semiconductor test portfolio with a 4881HV High Voltage Wafer Test System. The solution improves the productivity of power semiconductor manufacturers by enabling parametric tests up to 3kV supporting high and low-voltage in one-pass tests.
Manufacturers have traditionally measured wafers using separate testers for high and low voltages. However, demand for power semiconductors is rapidly growing due to their multifunctionality, higher performance, and next-generation devices such as silicon carbide (SiC) and gallium nitride (GaN). As a result, customers need a solution to more accurately and efficiently test their devices and reduce time to market.
Keysight’s new solution addresses critical challenges in power device manufacturing by enabling process control monitoring (PCM) and wafer acceptance testing (WAT). The test system offers several key benefits. It features high-voltage capability with a scalable high-voltage switching matrix (HV-SWM) supporting up to 3kV and 29 pins, allowing precise measurements from low current to sub-pA resolution, even at high voltage. This flexibility includes high-voltage capacitance measurement and parametric tests.
Additionally, the system enables one-pass testing, increasing productivity and efficiency by eliminating the need for separate high- and low-voltage test systems, reducing footprint and testing time. Integrated with Keysight’s SPECS-FA software, it also enhances factory automation. Finally, the system ensures safety and reliability with built-in protection circuitry, machine control, and compliance with SEMI S2 standards, safeguarding both operators and equipment from high-voltage surges.
Shinji Terasawa, Vice President and General Manager of Keysight’s Wafer Test Solutions said, “Keysight is thrilled to introduce our new wafer test system for power semiconductors, building on our long tenure of testing advanced semiconductors. Our mission is to lead the market by providing cutting-edge solutions that anticipate and meet the rapidly evolving needs of the semiconductor sector. This latest innovation exemplifies our unwavering commitment to the industry.”
