摘要:
The present invention relates to a semiconductor device with nanowire-type interconnect elements and a method for fabricating the same. The device comprises a metal structure with at least one self-assembled metal dendrite and forming an interconnect element (424) between a first and a second metal structure. The fabrication comprises providing an ambient environment adjacent to an interconnect surface region of a substrate that is suitable for allowing growth of at least one metal dendrite between the first and second metal structures, and initiating and sustaining self-assembly of a metal structure comprising at least one metal dendrite in the interconnect surface region between the first and second metal structures by irradiating the pn junction with photons of an energy suitable for creating free charge carriers in the first and second doped substrate regions and thus creating an electric potential difference between the first and second metal structures, which is suitable for electrolysis of metal from at least one of the first and second metal structures.
摘要:
A device for use in tissue repair, a method of using the device in a surgical procedure and a method of making the device. The device is an assembly of a cannulated anchor with a cord passed through it, and a stopper to prevent the cord from passing back through the anchor.
摘要:
In the field of immersion lithography, it is known to provide a liquid between an optical exposure system and a wafer carrying layers of photosensitive material to be irradiated with a pattern by the optical exposure system. However, bubbles are known to form or exist in the liquid, sometimes close to a surface of the wafer resulting in scattering of light emitted from the optical exposure system. The scattering causes the pattern recorded in the layers of photosensitive material to be corrupted, resulting in defective wafers. Therefore, the present invention provides a bubble displacement apparatus comprising a drive signal generator for driving a force generator arranged to generate a force in response to a drive signal generated by the drive signal generator. The force generated urges the bubble away from the surface.
