Wafer Preparation and Iodine-Ethanol-Ethanol Passivation Procedure for Reproducible Minority-Carrier Lifetime Measurement: Preprint

Research output: Contribution to conferencePaper

Abstract

This paper describes reasons that lifetime measurments may be irreproducible using iodine-in-ethanol (I-E) passivation. Possible factors include the strength of the iodine in ethanol solution, wafer cleaning procedures, influence of wafer container during lifetime measurement, and stability of I-E.
