METHOD FOR PRODUCING A ROLLED-UP ELECTRICAL OR ELECTRONIC COMPONENT

The present invention relates to the fields of physics, material sciences and micro and nano electronics, and concerns a method for producing a rolled-up electrical or electronic component, as can be used for example as a capacitor, or in aerials. The object of the present invention is to provide a low-cost, environmentally friendly and time-saving method for producing a rolled-up electrical or electronic component with many windings. The object is achieved by a method for producing a rolled-up component in which at least two functional and insulating layers, alternately arranged fully or partially over one another, are applied to a substrate with a sacrificial layer, wherein at least the functional or insulating layer that is arranged directly on the sacrificial layer has a perforation, at least on the two sides that are arranged substantially parallel to the rolling direction.

A MEMS device, e.g., a flexible MEMS pressure sensor, is formed by disposing a sacrificial layer, such as photoresist, on a substrate. A first flexible support layer is disposed on the substrate, and a first conductive layer is disposed over a portion of the first support layer. A liquid or gel separator, e.g., silicone oil, is disposed on an internal region of the first conductive layer. A second flexible support layer encapsulates the first conductive layer and the separator. A second conductive layer disposed over the second support layer at least partially overlaps the first conductive layer and forms a parallel plate capacitor. A third flexible support layer encapsulates the second conductive layer and second support layer. Soaking the sensor in hot water releases the sensor from the sacrificial layer.

Method for freeing a micromechanical part and a micromechanical part comprising sacrificial fasteners

A processing method for a wafer includes the steps of forming a frame unit having a ring-shaped frame, providing a resin sheet, fixing the resin sheet, which covers the wafer at its front side, at its outer peripheral edge, on the ring-shaped frame, forming through-holes in the resin sheet, holding the frame unit on a side of the resin sheet under suction on a holding surface to fix the ring-shaped frame, applying a laser beam to the wafer to form modified layers inside the wafer, and separating the resin sheet. In the holding step, the adhesive tape is suctioned under a negative pressure acting from the holding surface via through-holes while the front side of the wafer is prevented by the resin sheet from being suctioned on the holding surface.
