摘要:
A method of forming an aluminum containing film on a substrate includes providing a precursor having the chemical structure: AI(NR1R2)(NR3R4)(NR5R6); where each of R1, R2, R3, R4, R5 and R6 is independently selected from the group consisting of hydrogen and an alkyl group including at least two carbon atoms. The precursor is utilized to form a film on the substrate including at least one of aluminum oxide, aluminum nitride and aluminum oxy-nitride. Each of the R1 - R6 groups can be the same or different and can by straight or branched chain alkyls. An exemplary precursor that has is useful in forming aluminum containing films is tris diethylamino aluminum.

The aim of the invention is to obtain a largely water diffusion-tight encapsulation of electronic components at moderate temperatures of less than 300 °C, preferably less than 150 °C. To this end, the invention provides a method for forming housings for electronic components, particularly sensors, integrated circuits and optoelectronic components. This method comprises the following steps: providing a substrate (1), whereby at least one first substrate side (1a) is to be encapsulated; providing a vapor deposition glass source (20); placing the first substrate side (1a) relative to the vapor deposition glass source in a manner that enables the first substrate side (1a) to be subjected to a vapor deposition, and; vapor-depositing the first substrate side with a glass layer (4).
摘要:
The present invention provides a method for producing a crystalline metal oxide thin film by first depositing a substantially amorphous metal oxide film, and thereafter, as a post treatment, exposing the film to low temperature plasma in a high frequency electric field at 180°C or less, and the crystalline metal oxide thin film produced by this method. Because the producing method according to the present invention allows a dense and homogenous crystalline metal oxide thin film to be formed onto a substrate at a low temperature without requiring active heat treatment, a metal oxide thin film having desirable characteristics can be formed without damaging the characteristics of a substrate even if the substrate has comparatively low heat resistance.

Provided is a method for depositing a dielectric layer (13) on a substrate (11). Oxidation barrier layers (10) for preventing the oxidation and diffusion of a lower electrode are inserted into the interfaces between the substrate (11) and a dielectric layer (13) and between the dielectric layers (13, 15, 17). Accordingly, a capacitor having a low leakage current and a high capacitance is obtained. In addition, a dielectric constant is controlled by adjusting a lattice constant so that a multi-layer structure of high dielectric constant is formed on a large substrate.
