The preparation of thin films of zirconium oxide and hafnium oxide by decomposition of the diketonate complexes of these metals has been described in two earlier papers. The present paper deals with aspects of film growth. The rate of film growth (R) depends on the substrate temperature but as the temperature increases, powdery oxide forms rather than continuous film. R depends on the concentration of the diketonate in the gas phase only at low values of concentrations and is constant at higher concentrations. The optimal conditions for ZrO2 and lifO2 film deposition from organometallic compounds and the influence o~ oxygen on R are discussed.Chemical vapor deposition (CVD) of oxides finds increasing use in preparation of thin films for solidstate devices and protective coatings. For all these applications, control of stoichiometry, structure, physical, mechanical, and electrical properties is essential. Any knowledge of the mechanism or of the parameters involved in CVD is very helpful in de: vising means to control these critical properties. The thermal gas phase decomposition of p-diketonate complexes of zirconium and hafnium to form the corresponding oxides has been described in preceding papers (1, 2). The present paper describes details o~ the growth characteristics of thin films and their dependence on the experimental conditions.
