In a light-emitting element including an upper electrode, an electroluminescent layer, and a lower electrode, a short-circuited portion that is undesirably formed between the upper electrode and the lower electrode is irradiated with a laser beam, whereby a region where the short-circuited portion is removed is formed, and then the region is filled with an insulating resin having a light-transmitting property. Thus, the problem of the short circuit between the upper electrode and the lower electrode is solved and yield of a lighting device is improved.

  • Publication number: 20120068175
    Abstract: A method for fabricating an integrated circuit (IC) product and IC product formed thereby. The method includes designing an IC package having a plurality of IC connection sets, each configured to be connected to a corresponding IC selected from among a plurality of ICs, each having different functionality. Various IC products can be produced depending upon which selected IC is connected to its corresponding connection set, and the IC package can be cut during design to exclude IC connection sets corresponding to ICs that are not selected. By testing the complete IC package, a portion of the complete IC package can be fabricated, cut from the complete IC package, with significantly reduced design and testing requirements.

  • Publication number: 20120043650
    Abstract: An integrated circuit 15 is placed onto a lead frame 101 having lead fingers 109 of substantially constant thickness along their length. Wires are formed from the lead fingers 109 to corresponding electrical contacts the integrated circuit. Following the wire bonding process, the thickness of the tips of the lead fingers 109 is reduced by a laser process, to form tips of reduced thickness desirable for a subsequent moulding operation. Thus, at the time of the wire bonding the tips of the fingers 109 need not have a gap beneath them, so that more secure wire bonds to the lead fingers 109 can be formed.

A two-dimensional area covered by the die attach adhesive and a die attach dispense pressure can be used as a comparison with a reference value to determine whether the volume of die attach adhesive dispensed is sufficient. The reference value can take into account viscosity changes of the die attach adhesive, so that the volume of die attach adhesive dispensed during production can be determined. The volume dispensed can be automatically adjusted in situ during production using a computer system.

  • Patent number: 8111081
    Abstract: The present invention is a method for evaluating a silicon wafer by measuring, after fabricating a MOS capacitor by forming an insulator film and one or more electrodes sequentially on a silicon wafer, a dielectric breakdown characteristic of the insulator film by applying an electric field from the electrodes thus formed to the insulator film, the method in which the silicon wafer is evaluated at least by setting an area occupied by all the electrodes thus formed to 5% or more of an area of a front surface of the silicon wafer when the one or more electrodes are formed. This provides an evaluation method that can detect a defect by a simple method such as the TDDB method with the same high degree of precision as that of the DSOD method.
