The present invention relates to a method for producing mechanical stops for self-alignment, and to a device comprising stops for self-alignment. The method comprises dry etching and anisotropic etching of a first substrate (1) in order to produce at least one horizontal stop (8) and at least one vertical stop (4). At least one contact (3) composed of fusible material is deposited on the structured first substrate (1) and remelted. A second substrate (2) having at least one second contact composed of a material that can be connected to the fusible material of the first contact (3) is positioned on the first contact. Self-alignment of the two substrates (1, 2) subsequently takes place by virtue of the at least one remelted contact (3) being established in such a way that the interface energy is minimized.
摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von mechanischen Anschlägen zur Selbstjustage und eine Vorrichtung mit Anschlägen zur Selbstjustage. Das Verfahren umfasst Trockenätzen und anisotropes Ätzen eines ersten Substrats (1) zur Herstellung von mindestens einem horizontalen Anschlag (8) und mindestens einem vertikalen Anschlag (4). Auf dem strukturierten ersten Substrat (1) wird mindestens ein Kontakt (3) aus schmelzbarem Material abgeschieden und umgeschmolzen. Ein zweites Substrat (2) mit mindestens einem zweiten Kontakt aus einem mit dem schmelzbaren Material des ersten Kontakts (3) verbindbaren Material wird auf dem ersten Kontakt platziert. Anschließend findet eine Selbstjustage der beiden Substrate (1, 2) dadurch statt, dass sich der mindestens eine umgeschmolzene Kontakt (3) derart einstellt, dass die Grenzflächenenergie minimiert wird.

The ability to assemble three-dimensional structures using diamagnetic particles suspended in solutions containing paramagnetic cations is described. The major advantages of this separation device are that: (i) it is a simple apparatus that does not require electric power (aset of permanent magnets and gravity are sufficient for the diamagnetic separation and collection system to work); ii) the assembled structures can be removed from the paramagnetic solution for further processing after fixing the structure; iii) the assembly is fast; and iv) it is small, portable.

摘要:
A method and system for improving alignment precision of MEMS parts during manufacturing are disclosed. According to the invention at least one of the MEMS parts comprises a cavity wherein a sphere or bearing is centered and preferably temporary blocked with a temperature dissipative material. When MEMS parts are in contact of the sphere or bearing, the temperature dissipative material is evaporated, offering a very low friction against two facing MEMS parts moving in different directions, enabling a very precise positioning. In a first embodiment, each MEMS part comprises pads that are used in conjunction with soldering alloy for self-aligning the parts. In a second embodiment, each part comprises at least one cavity, the upper cavity having a conic shape and the lower cavity having a flat floor, the alignment being obtain when the stable state is reached i.e., when the sphere is centered on the cone center of the upper cavity.
