Abstract:
A method of growing a plurality of free-standing structures comprises providing a plurality of free-standing structures, each free-standing structure having a first end coupled to a substrate, and a terminal end; providing at least one laser beam, the laser beam having a beam waste at a point proximate to the terminal end of the free-standing structure; and moving one of the plurality of freestanding structures or the beam waste to provide a growth zone proximate to the terminal end of each of the free-standing structures such that the free-standing structures grow into the growth zones by addition of decomposing precursor components. The growth rates of each of the free-standing structures are substantially the same.
Abstract:
A method of fabricating a three-dimensional heterogeneous small-scale device includes the steps of depositing a fine heterogeneous materials (such as dry powders and biological materials) towards a substrate. In addition, the method includes sintering/cladding the material with a laser so as to produce a pattern. Then, the pattern is micro machined according to the particular design. The depositing step preferably includes providing a feed mechanism having an input to receive the material, an output, and a source of ultrasonic vibration to discharge the material from the output.
Abstract:
Methods for creating one or more structures in a micromachined device. In one arrangement, the methods include the steps of providing a substrate, forming upstanding nonconductive mold walls on the substrate so that first and second wells are formed, the second well being wider than the first well. The method further includes applying a first material to the surface of the wells so that the first well fills with the first material before the second well, and removing the first material from the second well while leaving a portion in the first well.
Abstract:
A method of forming nanomaterials (10) on packaged sensor- device platform, the method comprising the steps of fabricating (11) a sensor device platform on full scale wafer to form a fully packaged sensor device platform for nanomaterials forming process (10) which comprises the steps of protecting the wire bond with epoxy while leaving the sensing area exposed for receiving coating of catalyst precursor for the nanomaterial growth, nucleating (1.6) the coated catalyst precursor at low temperature for forming an active nanoparticle, and providing the active nanoparticle nucleation with nutrient solution for turning them into solid and forming nanostructures for integration of readout circuit for sensing.
Abstract:
A method of fabricating an integrated circuit includes forming (52) a metallic trace over a substrate. Resonance in the metallic trace can be induced (54), resulting in a resonating metallic trace and a localized heated target deposition region. A semiconductor material can be deposited on the target deposition region via gas decomposition (56) of a semiconductor precursor gas.
Abstract:
The invention relates to a lithographic method for producing microcomponents having a submillimeter structure, whereby the resist material can be dissolved in a simple manner. According to the invention, a structurable adhesive layer is applied to a metallic starting layer, a layer consisting of photostructurable epoxy resin is applied to the adhesive layer, and the epoxy resin is structured by means of selective illumination and dissolution of the unexposed regions in order to create supporting structures and free spaces between the supporting structures. Only the free spaces provided for the microcomponent and located between the epoxy resin supporting structures are then filled with metal according to a galvanic method, and the epoxy resin is removed, the remaining free spaces being filled with etching agents.

A method of fabricating a three-dimensional heterogeneous small-scale device includes the steps of depositing fine heterogeneous materials (such as dry powders and biological materials) towards a substrate (45). In addition, the method includes sintering or cladding the material with a laser so as to produce a pattern (46). Then, the pattern is micro machined according to the particular design (47). The depositing step preferably includes providing a feed mechanism having an input to receive the material, an output, and a source of ultrasonic vibration to discharge the material from the output.
Abstract:
Disclosed is a method for manufacturing a microcantilever having a predetermined thickness that includes forming a liquid synthetic resin for cantilevers to a thickness corresponding to the thickness of the microcantilever on an upper surface of a base block having an adhesive base and a non-adhesive base, and curing the liquid synthetic resin for cantilevers via a boundary between the adhesive base and the non-adhesive base, wherein the adhesive base has stronger adhesivity to the cured synthetic resin for cantilevers than the non-adhesive base.
