Abstract: A preparation for forming a thin film capacitor includes forming an amorphous ferroelectric film, such as barium strontium titanate [(Ba,Sr)TiO3] film, for use as an interface between a metal electrode and a polycrystalline ferroelectric film, such as (Ba,Sr) TiO3 film. The polycrystalline ferroelectric film serves as a dielectric layer of the thin film capacitor in view of the fact that the polycrystalline ferroelectric film has a high dielectric constant. The amorphous ferroelectric film serves as a buffer layer for inhibiting the leakage current of the thin film capacitor. The amorphous ferroelectric film is grown by sputtering and by introducing a working gas, such as argon, and a reactive gas, such as oxygen, into a reaction chamber in which a plasma is generated at room temperature.

Abstract: This invention discloses an in-situ monitoring method on the layer uniformity of sputter coatings in a vacuum chamber based on deconvolution of measuring plasma emission spectra. The method of the present invention started from an Ar-normalized Sr intensity distribution derived from deconvoluting the plasma spectra by using Abel inversion method, which was considered as the spatial distribution of the sputtering mass of the source target. The thickness profile on the substrate was then calculated with n-th power of cosine law model. It was observed good agreement between the calculated thickness profile based on spectroscopic measurement and experimental observation. The film uniformity for the same sputter conditions can be monitored by comparing in-situ measurement of Ar-normalized Sr intensity distribution with the standard curve, or by directly calculating thickness distribution on the substrates.

Abstract: The present invention disclose a method for measuring a thermal expansion coefficient of a thin film, in which the thin film is first deposited on two substrates having different thermal expansion coefficients under the same conditions. For each of the two deposited substrates, a relationship between the thin film stresses and the measuring temperatures is established by using a phase shifting interferometry technique, in which the stresses in the thin films are derived by comparing the deflections of the substrates prior to and after the deposition. Based on the two relationships the thermal expansion coefficient, and elastic modulus, E f ( 1 - v f ) , can be calculated, wherein Ef and &ngr;f are the Young's modulus and Poisson's ratio of the thin film, respectively.
