AbstractAn electron beam evaporation method has been used to prepare tin doped indium oxide (ITO) films with 95 wt.% In2O3 and 5 wt.% SnO2 in an oxygen atmosphere. It was found that the deposition rate and oxygen pressure strongly influence the film properties when the substrate temperature was lower than 200°C. In an optimal condition, highly transparent (transmittance ˜ 90% at wavelength 570 nm) and conductive (resistivity – 3×10−4Ω-cm) films of thickness around 2000 Å at substrate temperature as low as 180°C can be obtained.

Lower Substrate Temperature

3C-SiC films grown on carbonized Si (100) by plasma-assisted CVD have been investigated with systematic changes in flow rate of monosilane (SiH4) and propane (C3H8) as source gases. The deposition rate of the films increased monotonously and the microstructures of the films changed from 3C-SiC single crystal to 3C-SiC polycrystal with increasing flow rate of SiH4. Increasing C3H8 keeps single crystalline structure but results in contamination of α-W2C, which is a serious problem for the epitaxial growth. To obtain high quality 3C-SiC films, the effects of C3H8 on the microstructures of the films have been investigated by reducing the concentration of C3H8. Good quality 3C-SiC single crystal on Si (100) is grown at low net flow rate of C3H8 and SiH4, while 3C-SiC single crystal on Si (111) is grown at low net flow rate of C3H8 and high net flow rate of SiH4. It is expected that 3C-SiC epitaxial growth on Si (111) will take placed at a higher deposition rate and lower substrate temperature than that on Si (100).

Indium Tin Oxide (ITO) films were deposited on non-alkali glass substrate by magnetron sputtering using commercial ITO target (target A) and improved ITO target (target B). Depositions were carried out at total gas pressure (Ptot) of 0.5 Pa, substrate temperature (Ts) of RT ~ 300 °C, oxygen flow ratio [O2/(O2+Ar)] of 0 ~ 1.0% and dc power of 100W. Target B showed relatively higher stability in film resistivity with increasing sputtering time, i.e., erosion ratio of target surface. Optimum oxygen ratio to obtain the lowest resistivity was decreased with increasing substrate temperature. The lowest resistivity was 1.06x10-4 6cm for the film deposited using target B at O2/(O2+Ar) ratio of 0.05% and at Ts =300 °C.
