Abstract :
This paper describes the use and the design of a microelectronic test structure to show a new fast and simple DC method for measuring the dependence of carrier mobilities upon carrier concentration. The test structure is designed for reducing parasitic effects and providing reliable results up to the highest carrier concentrations. Numerical simulation is used for verification of the accuracy of the method for several test structure parameters. Experimental results are provided and represented by a simple fitting formula
