Industry members collaborate to create a semi-laboratory


Keysight Technologies Inc., a global test and measurement company, and the National Central University Optical Sciences Center (NCUOSC) announced a collaboration to improve the efficiency of test design and validation of gallium nitride applications ( GaN) and silicon carbide (SiC), accelerating the pace of 5G innovation and electric vehicles (EVs).

Wide bandgap (WBG) materials, such as GaN and SiC, offer fast switching speeds, low losses, and withstand high temperature and voltage characteristics. As a result, these materials are exploited in consumer power products, fast charging, electric vehicles and rail transportation, as well as 5G infrastructure and data center servers. However, these advantages increase the complexity of design and testing.

NCUOSC successfully used Keysight’s PD1500A Dynamic Power Supply Device Analyzer / Double Pulse Tester (DPT) platform to establish a third generation WBG open semiconductor lab to improve efficiency development and testing. As JEDEC, a global leader in the development of open standards and publications for the microelectronics industry, continues to define dynamic testing of WBG devices, standardized tests are beginning to emerge.

The Keysight PD1500A DPT determines key performance parameters, which match all standards, such as on / off and switching characteristics, dynamic on resistance, dynamic current and voltage, and reverse recovery , the gate load and the output characteristics of the device.

Reliable and repeatable measurements are essential

“Keysight is pleased to work with NCUOSC to help engineering teams characterize, understand, integrate, deploy and pilot innovations for next-generation semiconductor technologies,” said Thomas Goetzl, vice president and director General of the Automotive and Energy Solutions business unit at Keysight.

Reliable and reproducible measurements are essential to accelerate the design and validation of new technologies, including wide bandgap semiconductors. Keysight’s smart PD1500A DPT functions, such as fully automatic parameter extraction software based on IEC and JEDEC standards, loop testing, voltage and current sweep testing, and high temperature automatic testing can help to stimulate future innovations.

Innovate GaN and SiC applications

“Keysight’s DPT PD1500A enables NCUOSC to reliably characterize wide bandgap devices and effectively innovate GaN and SiC applications. Its optional, scalable, security guards provide the flexibility we needed for future expansions, ”said Prof. Yue-Ming Hsin, Director of NCUOSC. “In addition to the PD1500A, we have also configured the Keysight B1505A / N1265A power supply / plotter analyzer to serve the comprehensive and critical characterizations of WBG semiconductors. It is a pleasure to work with Keysight and contribute to the 5G / 6G and electric vehicle ecosystem.
