Agilent Technologies introduces industry's first single-box analyzer/curve tracer for 40-Amps/3000-Volt power device evaluation
Upgrade to Agilent B1505A power device analyzer/curve tracer meets demands of growing markets
The highpower device market is growing rapidly each year due to the demand for green engineering and products that conserve energy. Industry segments leading the growth are hybrid and other highefficiency cars; industrial uses such as robotics, solar cells, wind electricity and electric trains; and in information technology and consumer electronics CPU power control circuits that require a highly efficient power device for power conservation.
Power MOSFET and IGBT devices are being engineered to reduce energy loss, conserve power and decrease operating costs. Some new devices are using wideband gap materials such as silicon carbide (SiC) or gallium nitride (GaN) to achieve high efficiency. In addition, onwafer testing has become very important for reducing development turnaround times. The upgrade to 40A capability will increase the number of power devices and applications the Agilent B1505A can serve.
"Test and measurement of highpower devices is a growing requirement for manufacturers, yet one that demands the utmost accuracy and reliability," said Masaki Yamamoto, general manager of Agilent Hachioji Semiconductor Test Division. "Researchers and development engineers need to know they can be confident in their findings. Onwafer as well as packaged device 40A evaluations, are strong requirements in the marketplace because they help dramatically decrease time to market."
The Agilent B1505A is a singlebox solution that provides for ease of use and ease of analysis. Its new 40A capability comes from its ability to support two highcurrent source monitor units (HCSMUs) in a single device. Current owners of an Agilent B1505A with a HCSMU can easily add a second HCSMU with an accessory to enable 40A sourcing and measurement for both packaged and onwafer devices. The allinone design provides a simple and clean configuration for 40A sourcing and measurement, allowing easy setup and providing an uncluttered work environment with space for larger devices. The new design is unlike a measurement system built with multiple instruments, where complicated cabling and user safety considerations are required.
The Agilent B1505A can measure currents up to 40A and display the results in various formats including semilog or loglog graphs with extracted parameters. The interlock feature ensures safe operation by preventing electrical shock even with the increased current capacity. The module selector supports automatic switching between multiple types of SMU; this allows the measurement of key parameters, such as onresistance and breakdown voltage in a single measurement sequence. The tracer test mode, which now covers 40A as well as newly developed simultaneous sweep range control in positive and negative directions, provides intuitive and easytouse measurement with the same look and feel of the current marketleading Agilent B1505A, introduced in November 2008.
Also provided is a new socket module to support the test adapters widely used by conventional curve tracer users. This allows current curve tracer users to reduce migration costs when replacing old curve tracers with the stateoftheart Agilent B1505A.
Key features of the Agilent B1505A Power Device Analyzer/Curve Tracer with 40A capabilities include:
- device characterisation at 3000V and 40A in a single instrument with accuracy down to subpA;
- new accessories that allow clean and safe connection for 40A measurement for packaged devices and onwafer devices;
- capacitancevoltage (CV) measurements with high DC bias up to 3000V;
- a new accessory that supports test adapters widely used in conventional curve tracer; and
- simultaneous sweep range control in positive and negative directions.
The Agilent B1505A with 40A capability will be available for order beginning May 1, 2010.
