摘要:
The invention refers to an electromagnetic radiation sensor micro device for detecting electromagnetic radiation, which device comprises a substrate and a cover at least in part consisting of an electromagnetic radiation transparent material, and comprising a reflection reducing coating and providing a hermetic sealed cavity and an electromagnetic radiation detecting unit arranged within the cavity. The reflection reducing coating is arranged in form of a multi-layer thin film stack, which comprises a first layer and a second layer arranged one upon the other. The first layer has a first refractive index and the second layer has a second refractive index different from the one of said first layer. First and second layer are of such layer thickness that for a certain wavelength there is destructive interference. The invention also refers to a wafer element as well as method for manufacturing such a device.

The invention relates to a method for generation of a given internal pressure in a cavity of a semiconductor component, comprising preparation (S1) of the semiconductor component, whereby the semiconductor component has a semiconductor oxide region, arranged to pass between the cavity of the semiconductor component and an outer surface of the semiconductor component, exposure (S3) of the semiconductor component to a surrounding atmosphere comprising a noble gas at a first temperature for a given duration and setting (S5) a second temperature, different to the first, after expiry of the given duration, whereby the semiconductor oxide region has a higher permeability to the noble gas at the first temperature than at the second temperature.

The invention relates to a multiple component which is to be subsequently individualised by forming components containing active structures, in addition to a corresponding component which can be used in microsystem technology systems. Said multiple component and/or component comprises a flat substrate and also a flat cap structure which are bound to each other such that they surround at least one first and one second cavity per component, which are sealed against each other and towards the outside. Said component is characterised in that the first of the two cavities is provided with getter material and due to said getter material has a different internal pressure and/or a different gas composition than the second cavity. The invention also relates to a method for producing said type of component and/or components for which gas mixtures of various types of gas have a different absorption ratio in relation to the getter material.
