Am. Ionescu et al., A NEW LIFETIME CHARACTERIZATION TECHNIQUE USING DRAIN CURRENT TRANSIENTS IN SOI MATERIAL, Solid-state electronics, 39(12), 1996, pp. 1753-1755
A new technique based on the transient operation of the pseudo-MOS tra
nsistor is proposed for direct evaluation of generation lifetime and s
urface velocity in SOI wafers. The main advantages of the proposed tec
hnique are: (i) in situ operation (no prior processing ofa transistor)
, (ii) set-up simplicity, (iii) fast comparison of different SOI techn
ologies and (iv) simple identification of Si-film conductivity type. T
he influence of the electrical and non-electrical parameters of this t
echnique is systematically investigated. Various SOI wafers (SIMOX and
UNIBOND) are compared. Copyright (C) 1996 Elsevier Science Ltd
