RF Wafer Testing: An Acute Need, and Now Practical On GlobalSpec

Leading semiconductor producers have recently conceded that wafer level RF measurements are acutely needed to develop and produce advanced ICs. To a certain degree, this flies in the face of the 2003 recommendations by the ITRS Technical Working Group for Modeling and Simulation, which states, 'The parameter extraction for RF compact models preferably tries to minimize RF measurements. Parameters should be extracted from standard I-V and C-V measurements with supporting simulations, if needed.”
