摘要:
A method for assembling an electronic system with a plurality of layers. Recesses in formed in one or more dielectric layers and electronic components are positioned within the recesses. One or more layers containing the components are placed on a host substrate containing host circuits. Electrical interconnects are provided between and among the electronic components in the dielectric layers and the host circuits. The layers containing the components may also be provided by growing the electronic devices on a growth substrate. The growth substrate is then removed after the layer is attached to the host substrate.

An integrated communication device having a substrate layer of substantially electrically nonconductive material with two substantially parallel surfaces, an antenna element disposed on one of the surfaces, a ground layer of substantially electrically conductive material disposed on the other surface and having an opening formed therethrough opposite from the antenna element, and a transceiver device mounted to the ground layer to transmit and/or receive electromagnetic energy through the opening.
摘要:
A method for assembling components on a substrate including the steps of: (a) selectively coating at least a first receptor site of the substrate with a liquid precursor that forms a solid adhesive upon contact with an initiator; (b) providing each of the components with an adhesion surface that has the initiator; and (c) depositing the components on the substrate in a manner that causes a first of the components to contact the at least first receptor site whereupon contact between the initiator and the liquid precursor causes formation of the adhesive which affixes the first compound to the first receptor site. In a preferred embodiment of the invention, the precursor is a liquid monomer and the initiator initiates a polymerization reaction upon contact with the monomer to form a solid polymer.
摘要:
An interface material employing carbon nanotube (CNT) array and a method of fabricating the same. A first CNT array is provided on a first substrate. A second CNT array is provided on a second substrate. A first support layer is disposed on the first CNT array, wherein the first CNT array is between the first support layer and the first substrate. A second support layer is disposed on the second CNT array, wherein the second CNT array is between the second support layer and the second substrate. The first support layer is attached to the second support layer. The first and second substrates are removed, thereby providing the interface material.

摘要:
A method and apparatus for transporting and dispersing microstructures on a substrate by fluidic self-assembly. The apparatus has an assembly vessel that is tilted and rotated to apply uncaptured microstructures back onto the substrate as the assembly vessel rotates. The assembly vessel has ramp structures that collect the microstructures that have not been captured by the substrate at the lower edge of the assembly vessel, carry the microstructures as the assembly vessel rotates, and release the microstructures back on to the substrate at the upper edge of the assembly vessel. Vibrational energy may also be applied to the assembly vessel to assist in the dispersal and location of the microstructures on the substrate.
摘要:
A method for assembly including the steps of:(a) providing a plurality of microstructure components with each of the components having a bottom with the same three dimensional shape;(b) forming a mold with at least one protuberance from a surface thereof so that the at least one protuberance has the same shape;(c) molding a moldable substrate with the mold to form a molded substrate having a surface with at least one recess having the same shape; and(d) positioning a first of the plurality of microstructure components into said at least one recess. Each of the microstructure components may be formed by a masking and etching process, with the mold being formed by the same masking and etching process. The positioning step may consist of mixing the microstructure components with a fluid to form a slurry; and depositing the slurry on the surface of the molded substrate to cause the first of the plurality of microstructure components to self-align in the recess.

A method for fabricating a fuel cell component includes the steps of providing a mask having a plurality of radiation transparent apertures, a radiation-sensitive material having a sensitivity to the plurality of radiation beams, and a flow field layer. The radiation-sensitive material is disposed on the flow field layer. The radiation-sensitive material is then exposed to the plurality of radiation beams through the radiation transparent apertures in the mask to form a diffusion medium layer with a micro-truss structure.
