A Contactless Method for Determining the Carrier Mobility Sum in Silicon Wafers

Rougieux, Fiacre; Zheng, Peiting; Thiboust, Matthieu; Tan, Jason; Grant, Nicholas; MacDonald, Daniel; Cuevas, Andres


In this paper, we present a new method to determine the simultaneous injection and temperature dependence of the sum of the majority and minority carrier mobilities in silicon wafers. The technique is based on combining transient and quasi-steady-state photoconductance measurements. It does not require a full device structure or contacting but only adequate surface passivation. The mobility dependence on both carrier injection level and temperature, as measured on several test samples, is...[Show more]
