Patent ID: 8608376

Claim:
A method for modeling the performance of a laterally diffused metal oxide semiconductor (LDMOS) device comprising a package and a plurality of connector pins, the method comprising the steps of: a. positioning the device in an environment chamber operable to create a plurality of environment temperatures; b. connecting at least one of the pins of the device to a measurement system operable to measure at least one device characteristic; c. operating the environment chamber to set a first environment temperature, and acquiring a first value of the device characteristic from the measurement system; d. extracting a first temperature parameter set based on the first value of the device characteristic; e. operating the environment chamber to set a second environment temperature, and acquiring a second value of the device characteristic from the measurement system; f. extracting a second temperature parameter set based on the second value of the device characteristic, wherein each of the first and second temperature parameter sets comprise a temperature-dependent gain factor of a channel region of the device; and g. generating a temperature-scaling model for the device based on the first and second temperature parameter sets.
