Statistical sampling of new semiconductors
Once sample testing is complete, the designer moves on to statistical sample testing. The number of devices tested and the volume generated usually requires the use of a much more automated process. Although there are several vendors of automated power device test systems, such systems are expensive and the scope of the tests they can perform is often limited.
Fab feedback for new semi development
In some cases, when developing new integrated devices designers use the initial data they obtain to provide feedback to the fab, requesting a tweak of some process parameter, the better to establish the particular device characteristic for which they are looking. Once the designer is satisfied the device is ready, he or she moves on to a much more detailed sample testing phase.
Getting faster results when checking common parameters of experimental devices
When checking Drain Breakdown Voltage (BVDSS) manually, the voltage is slowly increased until a target current is reached. A faster, more efficient way to make this measurement is to source the target current and read the voltage at which the device settles. This requires an instrument that provides both an accurate, fast-acting voltage meter and a voltage clamp.
A typical workflow of a power semiconductor device holds many measurement challenges
The recent drive toward greater energy efficiency has created an increasing demand for better high power semiconductor devices such as diodes, FETs, IGBTs and others. New technologies hold the promise of higher performance, including lower ON-state losses, lower OFF-state leakage, faster switching, and reduced loss while switching.
