Abstract:
A method for forming a biological microdevice includes applying a biocompatible coarse scale additive process with an additive device and a biocompatible material to form an object. The coarse scale is a dimension not less than about 100 μm. The method also includes applying a biocompatible fine scale subtractive process with a subtractive device to the object. The fine scale is a dimension not greater than about 1000 μm. The method also includes moving the object between the additive device and the subtractive device. A system is also provided for performing the above method and includes the additive device, the subtractive device, a means for transporting the object between the additive device and subtractive device and a processor with a memory including instructions to perform one or more of the above method steps.
Abstract:
In one aspect, the invention includes a method of forming a void region associated with a substrate, comprising: a) providing a substrate; b) forming a sacrificial mass over the substrate; c) subjecting the mass to hydrogen to convert a component of the mass to a volatile form; and d) volatilizing the volatile form of the component from the mass to leave a void region associated with the substrate. In another aspect, the invention includes a method of forming a capacitor construction, comprising: a) forming a first capacitor electrode over a substrate; b) forming a sacrificial material proximate the first capacitor electrode; c) forming a second capacitor electrode proximate the sacrificial material, the second capacitor electrode being separated from the first capacitor electrode by the sacrificial material, at least one of the first and second electrodes being a metal-comprising layer; and d) subjecting the sacrificial material to conditions which transport a component from the sacrificial material to the metal-comprising layer, the transported component leaving a void region between the first and second capacitor electrodes.
Abstract:
L'invention concerne une machine d'usinage d'une pièce par micro- électroérosion comportant un mécanisme (44, 45, 46, 48) qui permet de modifier la configuration de la machine pour passer en alternance et de façon réversible d'une configuration d'usinage à une configuration d'affûtage dans laquelle la pointe d'une même électrode (20) de gravure et une autre électrode (64) sont plongées dans un bain (62) d'électrolyte pour réaliser un affûtage par attaque électrochimique de la pointe de l'électrode de gravure.
Abstract:
Methods for manufacturing a microstructure, wherein use is made of powder blasting and/or etching and a single mask layer with openings and structures of varying dimensions, characterized in that the mask layer at least at one given point in time has been wholly worn away within at least one region by mask erosion while the microstructure is not yet wholly realized. Use can be made of a combination of 'vertical' erosion, i.e. parallel to the thickness direction, and 'horizontal' erosion, i.e. perpendicularly of the thickness direction, of the mask layer. The horizontal mask erosion occurs at the edges of the mask structure. By selecting the size of the mask openings and the mask structures in a correct manner the mask layer in a region with smaller mask structures will be fully worn away at a given point in time, while in another region with larger structures the mask layer still has sufficient thickness to serve as protection against the powder blasting or etching.
Abstract:
Beschrieben wird ein Verfahren zur Oberflächenbehandlung einer elektrisch leitenden Substratoberfläche, bei dem ein festes Ionen leitendes Material in Form von ZrO 2 aufweisendes Werkzeug wenigstens bereichsweise in Kontakt mit der Substratoberfläche, die Kohlenstoff wie etwa Graphit und/oder Glaskohlenstoff enthält, gebracht wird, das als anionischer Ionenleiter ausgebildet ist und an das ein elektrisches Potenzial angelegt wird, so dass aus dem anionischen Ionenleiter Anionen austreten, die sich an der Substratoberfläche zu einer mit der Substratoberfläche reaktiven Verbindung umwandeln, und dass die reaktionsfähige Verbindung mit dem Graphit oder Glaskohlenstoff an der Substratoberfläche eine gasförmige Verbindung eingeht, wodurch die Substratoberfläche lokal abgetragen wird.
