Abstract:
The present invention provides a semiconductor device package having multi-chips with side-by-side configuration comprising a substrate with die receiving through holes, connecting through holes structure and first contact pads on an upper surface and second contact pads on a lower surface of the substrate. A first die having first bonding pads and a second die having second bonding pads are respectively disposed within the die receiving through holes. The first adhesion material is formed under the first and second die and the substrate, and the second adhesion material is filled in the gap between the first and second die and sidewall of the die receiving though holes of the substrate. Further, bonding wires are formed to couple between the first bonding pads and the first contact pads, between the second bonding pads and the first contact pads. A dielectric layer is formed on the bonding wires, the first and second die and the substrate. A build up layer is form on the lower surface of substrate and the back side of first and second die.
Abstract:
A process for preparing the drug-loaded cyanoacrylate nanoparticles is described. The cyanoacrylate nanoparticles which effectively deliver biological and therapeutic agents are synthesized by miniemulsion polymerization with surfactant, pluronic F127 or F68. Before initiation of polymerization, active agents with particularly highly hydrophobicity are dissolved in cyanoacrylate monomer. Compared with the drug-loaded polyalkylcyanoacrylate nanoparticles produced by emulsion polymerization, those produced by miniemulsion polymerization possess higher loading and encapsulation efficiencies. While the content of dissolved agents increases, furthermore, the loading and encapsulation efficiencies increase concurrently.
Abstract:
A window for an acid-base tank suitable for arrangement on a cleaning machine including at least one acid-base tank with an opening on a sidewall of the acid-base tank is described. The window for the acid-base tank at least includes a supporting plate, an annular washer, a transparent observe window and a transparent separation plate. The supporting plate has the same shape as the opening on the sidewall of the cleaning machine, is disposed on the opening, and has a first window opening. The annular washer is disposed on the supporting plate around the first window opening. The transparent observe window is pressed and covered on the annular washer. The transparent separation plate located between the supporting plate and the acid-base tank is disposed on the supporting plate and covers the first window opening. Furthermore, the chemical resistance of the transparent separation plate is better than that of quartz.

This invention discloses a light emitting diode, a wafer level package method, a wafer level bonding method, and a circuit structure for a wafer level package. The light emitting diode includes a package carrier, a conducting material, at least one light emitting diode structure and a package material. The package carrier has at least one package unit and two through holes on the package carrier and corresponding to the package unit. The conducting material is disposed in the through holes and formed at the bottom of the package unit. The light emitting diode structure is formed on a substrate. The substrate having a light emitting diode structure is flipped over in the package unit, and the electrodes of the light emitting diode structure are bonded with the conducting material. After the substrate is removed, a package material is stuffed in the package unit or on the light emitting diode structure.
Abstract:
A coupling device of a pair of safety goggles for use in a hat brim of the present invention is designed for coupling a fastening belt of the safety goggles with the hat brim of a hat body. The coupling device has a base having an outward extended arched gap, wherein the base is relatively rotatable so as to allow the hat brim of the hat body to be rotated into the gap of the base. In addition, the base is coupled with a hooking body for further coupling with the fastening belt of the safety goggles. Accordingly, the coupling device of the present invention can be assembled easily and conveniently.
Abstract:
A chip antenna module with two loops is disposed on a ceramic housing for receiving two different frequencies, and an adjustable matching loop is disposed on the housing for shortening the development time of the antenna module by means of adjusting the adjustable matching loop. The chip antenna module comprises a ceramic housing, a first loop, a second loop, and a matching loop. The first loop is disposed on a top surface of the housing for receiving a first frequency, the second loop is disposed on a top surface of the housing for receiving a second frequency, and the matching loop is disposed on a bottom surface of the housing for adjusting a matching impedance. In order to satisfy the system requirements of the matching impedance, a user can simply adjust the path of the matching loop via the special loop design of the matching loop.
