摘要:
A process for producing a thin film of a crystalline metal oxide, which comprises depositing a film of a metal oxide which is mainly amorphous and then subjecting it to a post-treatment in which the film is exposed to a low-temperature plasma in a high-frequency electric field at a temperature not higher than 180°C; and a thin film of a crystalline metal oxide produced by the process. By the process, a thin crystalline metal oxide film which is dense and homogeneous can be formed on a substrate at a low temperature without the need of a positive heat treatment. A thin metal oxide film having desirable properties can hence be formed even on a substrate having relatively low heat resistance without impairing the material properties of the substrate.
摘要:
A semiconductor device comprising a semiconductor substrate with a plurality of photodiodes arranged in the semiconductor substrate with interconnect layers defining apertures at the photo-diodes and a first polymer which fills the gaps such as to cover the photo-diode. Further, layers of color filters are arranged on top the gap filling polymer layer opposite to the photo-diodes and a second polymer arranged on the interconnect layers covers and planarizes and passivates the color filter layers. On top of the planarizing polymer there is a plurality of micro-lenses opposite to the color filters, and a third polymer layer is deposited on the microlenses for passivating the micro-lenses. According to the invention the polymer materials are comprised of a siloxane polymer which gives thermally and mechanically stable, high index of refraction, dense dielectric films exhibiting high-cracking threshold, low pore volume and pore size.

A high-quality semiconductor device is disclosed in which deterioration in transistor characteristics and increase of interfacial layer ascribable to a gate insulating film are suppressed. A method for manufacturing such a semiconductor device is also disclosed. The semiconductor device comprises an interfacial layer, a diffusion-suppressing layer and a high-dielectric-constant insulating film formed in this order on a surface of a silicon substrate.
摘要:
An integrated circuit capacitor is formed by first forming a first dielectric layer (25) over a semiconductor (10). A copper structure (35) is formed in the first dielectric layer (25) and a second dielectric layer (80) is formed over the copper structure (35). A metal containing layer (90) is formed over the second dielectric layer (80) and the copper structure (35) and a planar surface is formed by removing portions of the metal containing layer (90) and the second dielectric layer (80). The second dielectric layer (80) can comprise a high-k dielectric material. The metal containing layer can comprise two metal layers.

The aim of the invention is to provide a method for producing microstructures in glass or in glass-like layers. To this end, an auxiliary substrate (10, 20) having a structured surface (20a) is used, whereby the surface defines a negative mold for the product to be produced. A layer (30) made of glass or of a glass-like material is vapor-deposited onto the structured surface (20a) of the auxiliary substrate. The auxiliary substrate is subsequently removed, e.g. by using wet-chemical techniques, whereby exposing the positive structure. The invention enables the excellent production of microchannels and optical microstructures such as microlenses.
摘要:
In a method of manufacturing oxide thin film by adsorbing or depositing oxide forming starting material on a substrate followed by oxide formation, by using water in a liquid state to manufacture the oxide thin film, the advantages of the ALD method are utilized while resolving the tendency to leave impurities in the oxide film produced that is a drawback thereof, so that oxide thin film can be obtained having a reduced concentration of impurities.
