Minority Carrier Lifetime Properties of Reactive Ion Etched p-Type Float Zone Si

Deenapanray, Prakash; Horteis, M; MacDonald, Daniel; Weber, Klaus


Quasi-steady-state photoconductance (QSSPC) and deep level transient spectroscopy (DLTS) were used to characterize the minority carrier lifetime properties of reactive ion etched p-type Si. The effective lifetime of the plasma-processed samples degraded after etching, with the densities of recombination centers increasing linearly with etch time. Evidence is provided for the long-range (> 2 μm) migration of defects in the plasma-etched samples. A discrete defect with energy position at (0.32 ±...[Show more]
