    Abstract: Disclosed is a method for producing a mesoporous titanium dioxide thin film from a titanium precursor by using a polymer-grafted alumina composite as a support. The porous titanium dioxide thin film is obtained by using the polymer-grafted hybrid alumina composite as a support for sol-gel reaction, and thus it has a mesoporous structure and high surface area, thereby providing a high dye adsorption ratio. Therefore, a dye-sensitized solar cell using the mesoporous titanium dioxide thin film as a photoelectrode material has high energy conversion efficiency. In addition, it is possible to improve the long-term stability of a dye-sensitized solar cell through efficient infiltration of high-viscosity polymer and solid electrolyte as well as liquid electrolyte.

  • Patent number: 8883014
    Abstract: A monolithic fabrication method of parallel-plate electrowetting-on-dielectric (EWOD) chips for digital microfluidics of picoliter droplets is disclosed. Instead of assembling a second substrate to form a top plate, the top plate is generated in situ as a thin-film membrane that forms a monolithic cavity having a gap height on the order of micrometers with excellent accuracy and uniformity. The membrane is embedded with EWOD driving electrodes and confines droplets against the device substrate to perform digital microfluidic operations. Two main attributes of the monolithic architecture that distinguish it from tradition methods are: (i) it enables excellent control of droplet dimensions down to the micrometer scale, and (ii) it does not require the typical alignment and assembly steps of the two plates.

    Abstract: Disclosed is a microetching solution, a replenishment solution added to said microetching solution and a method for production of a wiring board using said microetching solution. The microetching solution for copper consists of an aqueous solution containing a cupric ion, an organic acid, a halide ion, a polymer and a nonionic surfactant. The polymer is a water-soluble polymer including a polyamine chain and/or a cationic group and having a weight average molecular weight of 1000 or more. In the microetching solution of the present invention, a value of AB is 2000 to 9000 and a value of A/D is 500 to 9000, where a concentration of the halide ion is A % by weight, a concentration of the polymer is B % by weight and a concentration of the nonionic surfactant is D % by weight. Using this microetching solution, adhesion to a resin or the like can be uniformly maintained even with a low etching amount.

    Abstract: Systems and methods for producing micromachined devices, including sensors, actuators, optics, fluidics, and mechanical assemblies, using manufacturing techniques of lead frames, substrates, microelectronic packages, printed circuit boards, flex circuits, and rigid-flex materials. Preferred embodiments comprise using methods from post-semiconductor manufacturing to produce three-dimensional and free-standing structures in non-semiconductor materials. The resulting devices may remain part of the substrate, board or lead frame which can then used as a substrate for further packaging electronic assembly operations. Alternatively, the devices may be used as final components that can be assembled within other devices.

  • Publication number: 20140311243
    Abstract: An apparatus (36) includes a motion amplification structure (52), an actuator (54), and a sense electrode (50) in proximity to the structure (52). The actuator (54) induces an axial force (88) upon the structure (52), which causes a relatively large amount of in-plane motion (108) in one or more beams (58, 60) of the structure (52). When sidewalls (98) of the beams (58, 60) exhibit a skew angle (28), the in-plane motion (108) of the beams (58, 60) produces out-of-plane motion (110) of a paddle element (62) connected to the end of the beams (58, 60). The skew angle (28), which results from an etch process, defines a degree to which the sidewalls (98) of beams (58, 60) are offset or tilted from their design orientation. The out-of-plane motion (110) of element (62) is sensed at the electrode (50), and is utilized to determine an estimated skew angle (126).

  • Patent number: 8858808
    Abstract: A method of thin printed circuit board wet process consistency on the same carrier, and more particularly to a printed circuit board in the developing, copper plating, stripping, etching and other wet processes uses the same frame as a carrier from the beginning to the end of the wet process, such that the thin printed circuit board is conducted a continuous and automatic wet process to avoid disassembly, storage and transportation between each process. Moreover, when using the flame, the thin printed circuit board is smooth and flattening in the wet process for avoiding “water effect,” the effective area is not exposed to any mechanical members for preventing scratches, and there are point contacts between the thin printed circuit board and the frame for preventing chemical residue. Accordingly, the present invention can not only enhance the yield of the thin printed circuit board but also shorten the production time.
