S. Honda et al., THE EFFECTS OF OXYGEN-CONTENT ON ELECTRICAL AND OPTICAL-PROPERTIES OFINDIUM TIN OXIDE-FILMS FABRICATED BY REACTIVE SPUTTERING, Thin solid films, 282(1-2), 1996, pp. 206-208
We have investigated the depth profile of the oxygen content of indium
tin oxide (ITO) films fabricated by reactive sputtering. The oxygen c
ontent was determined by means of O-16(alpha,alpha)O-16 resonant backs
cattering. The effect of the oxygen partial pressure of reactive gas o
n the oxygen content of the films was investigated. From the depth pro
file of oxygen, it was found that the oxygen compositions of the films
, especially in the surface region, changed with the oxygen partial pr
essure. Also it was found that the electrical and optical properties o
f the ITO films changed with the oxygen partial pressure. The correlat
ion between the oxygen content and the electrical and optical properti
es is discussed.
