Determination of Carrier Lifetime from MOS Capacitors

MOS Capacitors were used to determine minority carrier lifetimes by obtaining capacitance vs time data (C-U. A test system, utilizing an IBM PC as the driver for a Princeton Applied Research model 410 C-v plotter, Kiethley programmable power supply, and HP4145 parameter analyzer, was built to obtain the C-t data. The data can then be down-loaded to the VAX mainframe computer and analyzed by various FORTRAN programs, using analytical techniques developed by people such as, Zerbst, Schroder and Guldberg, Heiman, and others
