Physical Properties of Thin Metal Films -II (-Effect of Oxygen on Thin Metal Film Formation and Physical Properties-

금속박막의 물리적 성질 -II- -금속박막형성과 물성에 미치는 산소의 영향-=

Films of Cr, Cu, and Al were deposited by the evaporation technique at the high vacuum level-high evaporation rate and the low vacuum level-low evaporation rate. We measured sheet resistance and light transmittance, and observed microstructure and diffraction pattern by TEM, and investigated oxygen content in thin film by AES. We discussed the relations among microstructure, sheet resistance, and light transmittance with AES data. We found that the films deposited at the high vacuum level-high evaporation rate have small oxygen content in thin film comparing to the films deposited at the low vacuum level-low vacuum level-low evaporation rate, and that the films having crystalline structure and larger grain size were formed in the case of the high vacuum level-high evaporation rate and they showed lower sheet resistance and lower light transmittance.
