摘要:
In a method for manufacturing electronic parts by laminating metal thin films and insulating thin films on a support, a mold releasing agent is applied to the support before the start of lamination. Alternatively, the mold releasing agent is applied to the surface of the laminate during the lamination step, and then lamination is resumed. Therefore, the laminate can be prevented from cracking when the laminate is separated from the support or divided into plural pieces in the lamination direction. Thus, the reliability and productivity of electronic parts improve.

In a method wherein, before forming a thin film of, for example, metal on a supporting base in a vacuum, a vapor stream of patterning material for forming a pattern in the thin film is applied from nozzle holes, and the thin film is formed after this liquid has been adhered onto the supporting base, the patterning material is applied from the nozzle holes in such manner that it unifies on the supporting base. Thus, even when the pattern width is enlarged, a pattern can be formed in which the blurring at the pattern edges is small.

An electronic component provided with a dielectric thin film (4), normal electrodes (1a, 1b) formed on the thin film (4), dummy electrodes (2a,2b) formed on the dielectric thin film (4) with an insulating region (20) therebetween, and auxiliary electrodes (3) provided on both side faces of the component, wherein the width of the insulating region (20) is not less than 500 times the thickness of the dielectric thin film (4) so as to improve the characteristics such as the equivalent series resistance. Thus, the deterioration of the frequency characteristics caused by the dummy electrodes can be remedied and the component can be used for a capacitor or the like.

A method for manufacturing a capacitor includes the step of depositing metal thin film layers and resin layers alternating with each other, thereby forming a layered product. The thickness of the resin layer and the metal thin film or the width of margins are measured during the deposition. At a predetermined point in the process of the deposition, the number of layers to be deposited further is determined, based on the measured values and an intended electrostatic capacitance or deposition thickness. The thus obtained capacitor has the intended electrostatic capacitance or deposition thickness with a small dispersion.

A high definition plasma display panel which can display a video of a higher brightness and yet can be driven at a low power consumption is realized. To this end, a plasma display panel includes front panel including display electrode formed on glass substrate, dielectric layer covering display electrode, and protective layer formed on dielectric layer; and a rear panel opposing to front panel to form a discharge space filled with discharge gas, and including an address electrode formed along a direction intersecting with display electrode, and a barrier rib partitioning the discharge space. Protective layer is formed of a metal oxide made of magnesium oxide and calcium oxide and contains zinc. In an X-ray diffraction analysis on a surface of protective layer, a diffraction angle where a peak of the metal oxide occurs exists between a diffraction angle where a peak of the magnesium oxide occurs and a diffraction angle where a peak of the calcium oxide occurs.
