摘要:
An electric arc ion plating apparatus to coat a metal material on an object includes: (a) an vacuum chamber; (b) an electric arc bombardment chamber in the vacuum chamber, comprising an anode, a cathode target, and an arc triggering electrode to generate metal particles when a voltage is applied on the anode and the cathode, and on the arc triggering electrode; and (c) a magnetic coil having a longitudinal axis. The magnetic coil emanates from the electric arc bombardment chamber and encloses at least a part of the electric bombardment chamber. The magnetic coil contains a constant-diameter section enclosing and immediately emanating from the electric arc bombardment chamber to guide the metal particles away from the cathode and toward the object, and a varying-diameter section away from the electric arc bombardment chamber to provide optimum distribution of the metal particles before they reach the object surface. The varying-diameter section can be a diverging section for effectively coating relatively large objects, or a converging section for efficiently coating a relatively small object.

Disclosed is a thermally conductive, electrically insulating composite film, including interface layers disposed on the top and bottom surface of a metal substrate, and an insulation layer. Because the film has thermal conductivity and electric insulation properties, it can be disposed between the chips of a stack chip package structure, thereby dissipating the heat in horizontal and vertical directions simultaneously.

An apparatus for measuring thermal diffusivity includes a Raman spectroscope, a heating device, and a signal analyzing unit. The Raman spectroscope is utilized to measure a Raman scattering intensity of different sites of a film to be measured. The heating device is utilized to provide a controllable thermal driving wave. The signal analyzing unit is utilized to analyze the Raman scattering intensity from the Raman spectroscope and the thermal driving wave so as to evaluate the thermal diffusivity of the film to be measured.

A vacuum coating apparatus is disclosed. The apparatus includes a cathode target, a plurality of anodes, a transiting device, a pulsed arc discharge device, and a pulsed laser device. The plurality of anodes is placed on the transiting device and successively passes though a working position by the transiting device. The pulsed arc discharge device is electrically connected to the cathode target and the anode at the operable position to form plasma in a vacuum chamber for film coating. The pulsed laser device is located outside of the vacuum chamber and provides a pulsed laser beam onto the surface of the cathode surface to serve as a plasma trigger. A coating method for the vacuum coating apparatus is also disclosed.
