A liquid bridge was created and disconnected to transfer a controlled volume of mixture to a cylindrical post for the formation of parabolic lens shapes. We investigated a transferred volume and the focal length of the lens shape in terms of four parameters: post radius, withdrawal speed, dipping depth, and mixture thickness. The presented method is simple and flexible to transfer a pre-analyzed volume and subsequently to fabricate a lens shape on post structures, which can be beneficial to implementing self-aligned and smooth lenses integrated in micro structures.

-Novel fabrication method of nanobridge array of various materials was proposed using suspended silicon nanowire array as a sacrificial template structure. Nanobridges of various materials can be simply fabricated by direct deposition with thermal evaporation on the top of prefabricated suspended silicon nanobridge arrays, which are used as a sacrificial structure. Since silicon nanowire can be easily removed by selective dry etching, nanobridge arrays of an intended material are finally obtained. In this paper, metal nanobridges of Ti/Au, around 50-200 nm in thickness and width, 5-20 μm in length were fabricated to prove the advantages of the proposed nanowire or nanobridge fabrication method. The nanobridges of Ti/Au after complete removal of sacrificial silicon nanowire template were well-established and bending of nanobridge caused by the tensile stress was observed after silicon removing. Up to 50 nm and 10 μm of silicon nanowire in diameter and length respectively was also very useful for nanowire templates.
