A device and a method for transferring microstructures from a tool to a substrate which is to be structured. The device and method are intended to align the tool and the substrate in a mutually controlled manner. The device contains supports for the tool and the substrate which can be displaced in an opposing direction in relation to one another, resulting in an alteration of the distance between the tool and the substrate. A measuring system is provided which can be inserted between the supports, for measuring selected locations on at least one measuring plane. The direction of displacement of the supports is aligned vertically in relation to said measuring plane. The measuring system forms a fixed spatial relationship with the tool in a measuring position. The substrate can be aligned in relation to the tool. The method and device can be used for producing microstructured components.

The object, in a device and a method for separating a shaped substrate from a stamping tool, is to make demolding more functionally reliable and to substantially prevent damage to expensive components. A closeable chamber, the mutually moveable chamber parts of which are the support for the stamping tool and for the shapeable substrate, contains a substrate holder which, when the chamber is closed, fixes. the substrate to its support outside the stamping area, with the result that the substrate is detached from the stamping tool when the chamber is opened. The device and method can be used for the production of microengineered components.

The apparatus and process to compensate for variations in thickness of molding tools and of moldable materials used in an embossing process to be carried out under a vacuum, while ensuring high dimensional stability, and to ensure different molding depths. For achieving this object, a chamber is employed having a pair of oppositely lying chamber parts, of which one is fixed to the framework and the other is adjustable, having side walls which comprise an inner part and an outer part. The inner part is fastened to the fixed chamber part and the outer part, on the outwardly facing end face to of which the adjustable chamber part comes to bear against the force of a spring during the closing of the chamber, is displaceable along guide elements on the fixed chamber part between two stops. Within the chamber there takes place a setting of atmospheric conditions and of temperature conditions at points in time of the closing of the chamber at which an increase in a force acting on the fixed chamber part reaches predetermined values. Apparatus and processes employing such chamber are used in the production of microsystem components
