Problems solved by technology

However, it proves problematic here that the use of such a U-shaped profile requires a large number of struts over a large area, which produces a large amount of undesired heat conduction
For this reason, a tight anodic bond can hardly be achieved in this way over the entire area, since the same contact with the glass cannot be achieved over the entire area.
[0013] Anodic bonding was also considered for the manufacture of microelectromechanical systems (MEMS), but could not be implemented

Embodiment Construction

[0060] exist Figure 1a with 1b The embodiment shown in first provides two plate-shaped glass elements 2a and 2b, which have previously been subjected to a cleaning step. The two glass elements are basically aligned horizontally and are initially set at a distance d1 above and below, as in Figure 1a shown. The distance d1 is chosen such that a problem-free venting is then possible, correspondingly eg 5 cm. The lower glass element 2 a is covered with a layer 4 of a tin alloy. As will be explained in more detail below, this is a low-melting tin alloy with a melting point of up to 350° C., which contains at least one reactive metal as an alloy constituent. The geometry of the cut layer 4 corresponds to the bonding region to be bonded in a media-tight manner. For example, to form a media-tightly closed interior 6 between the two glass elements 2a and 2b, a frame-shaped layer 4 is used that surrounds the glass elements in the vicinity of their edges.

[0061] The two glass e...

Abstract

A composite object comprises two components (2a, 2b) made of an oxidic material, which at an elevated temperature conducts ions, said components being connected to each other in a medium-tight manner by way of a solder bridge (4) in a connecting region (6) located in between. In order to form a reliable connection, it is proposed that the solder bridge is formed by a low-melting tin alloy that has a weight proportion of at least 65% tin and a melting point of no more than 350 C and comprises at least one activating metal as an alloying constituent.

Description

technical field [0001] The invention relates to a composite material (Verbundobjekt) having the preamble of claim 1 and to a method for producing the composite material. Background technique [0002] Composite materials of this type, for example for microelectromechanical systems (MEMS) and in the form of highly insulating laminates or packages in semiconductor technology, are known in large numbers. [0003] With regard to the first application, a great improvement in the thermal insulation capacity is achieved by a two-layer sheet of sandwich construction, the cavity of which is kept at vacuum. The same applies to multi-layer sheets. [0004] In order to produce such glass composite materials, it is known to bond components, in particular glass sheets, which are to be composited together, in a hermetically sealed manner by means of a joining process, in particular a welding process. The soldering process is usually carried out at atmospheric pressure and the resulting ca...
