Title: Method of determining generation lifetime and doping profile using simultaneous high frequency capacity voltage measurements on metal insulator semiconducting structures
Inventor: SORGE ROLAND
IPC: H01L21/66
Filed: 1997-01-22
Granted: 1998-04-09
Abstract: The method involves measuring MOS-CV characteristics. The measurement of different MOS parameters from simultaneously measured MF/LF-MOS-CV characteristics is enabled through the use of a generally valid measurement and evaluation algorithm. The CV-characteristics are measured starting from a state of deep depletion in the accumulation direction, whereby a decreasing depletion zone width which accelerates the relaxation process is achieved. The equilibrium spatial charge zone depth is determined from the HF/LF-MOS-CV characteristics at the transition point from generation to recombination at the common intercept of the recorded HF-CV and LF-CV characteristics.
