摘要:
At least one shielding device, which protects the vacuum chamber walls and/or the components arranged in the chamber from undesired deposits of the layer starting material is arranged in the vacuum chamber of a coating installation according to the invention in which vitreous, glass-ceramic and/or ceramic layers are applied to substrates by deposition from the gas phase. It is important that in the event of temperature changes in the vacuum chamber, the expansion or contraction of the shielding device corresponds to the expansion or contraction of the vitreous, glass-ceramic or ceramic layer or deposits.

The invention relates to a cleanroom-capable coating system for PVD or CVD processes having at least one vacuum coating chamber, in which vitreous, glass-ceramic and/or ceramic layers deposited. A first opening of the vacuum coating chamber is connected via a separately evacuable vacuum airlock chamber (load lock) to a cleanroom, the vacuum airlock chamber comprising transport means for delivering substrates into the vacuum coating chamber and for taking substrates out of the vacuum coating chamber, and a second opening of the vacuum coating chamber connects the vacuum coating chamber to a grayroom area separated from the cleanroom.

A method for the patterned coating of a substrate with at least one surface is provided. The method is suitable for the rapid and inexpensive production of precise patterns. The method includes the steps of: producing at least one negatively patterned first coating on the at least one surface, depositing at least one second layer, which includes a material with a vitreous structure, on the surface, and at least partially removing the first coating.

To improve the radio-frequency properties of radio-frequency substrates or radio-frequency conductor arrangements, the invention proposes a glass material for producing insulation layers for radio-frequency substrates or radio-frequency conductor arrangements, which, as an applied layer, in particular with a layer thickness in the range between 0.05 μm and 5 mm, has a loss factor tan δ of less than or equal to 70*10−4 in at least a frequency range above 1 GHz.

The invention is therefore based on the object of providing a substrate having a metallic surface and a vitreous coating. Accordingly, the invention provides a process for producing a coated substrate or a product having a coated substrate which has at least one metallic surface coated with a glass, the substrate being coated with an evaporation-coating glass at least on the metallic surface.

The invention relates to processes for producing copy protection for an integrated circuit. To avoid unauthorized copying of an integrated circuit, it is an object of the invention to provide an effective and reliable copy protection. The invention proposes a process comprising the steps of providing a substrate (1) which has semiconductor structures (2) on at least a first side (1a) of the substrate (1), providing a material (23) for coating the substrate (1), coating the substrate (1) with a copy-protect layer (4). It has proven particularly advantageous for the copy-protect layer (4) to be produced by applying a silicate glass by evaporation coating, since this means that an etching process which dissolves the copy-protect layer also attacks the substrate (1), in such a manner that the semiconductor structures (2) are at least partially destroyed.

The invention is based on the object of providing a process for producing microstructures in glass or layers similar to glass. For this purpose, an auxiliary substrate (10, 20) having a structured surface (20a). is used, the surface defining a negative mold for the product which is to be produced. Then, a layer (30) of glass or a material similar to glass is applied to the structured surface (20a) of the auxiliary substrate by evaporation coating. Then, the auxiliary substrate is removed, for example by wet-chemical means, in such a way that the positive structure is uncovered. The invention makes it possible to produce excellent micro-channels and optical microstructures, such as micro-lenses.

The invention relates to a process for joining substrates having electrical, semiconducting, mechanical and/or optical components, and to a composite element. The process is to be suitable for the substrates which are to be joined substantially irrespective of material and in particular also for sensitive substrates, is to have a high chemical and physical stability and/or is to produce a hermetic cavity. According to the invention, a raised frame, in particular formed from anodically bondable glass, is applied by evaporation coating to one of the two substrates in order to serve as a joining element.

The invention provides a process for producing a substrate having a conductor arrangement that is suitable for radio-frequency applications, with improved radio-frequency properties. For this purpose, the process includes the steps of: depositing a structured glass layer having at least one opening over a contact-connection region by evaporation coating on the substrate, and applying at least one conductor structure to the structured glass layer so that the at least one conductor has electrical contact with the contact-connection region.
