  • Patent number: 7825750
    Abstract: Disclosed relates to an electromagnetic interference (EMI) filter. Capacitance and resistance or inductance of an EMI filter, which includes a resistor and a capacitor or an inductor and a capacitor, can be controlled, such that a cutoff frequency can be freely controlled without manufacturing a separate EMI filter according to a characteristic of a desired cutoff frequency. Further, an intelligent EMI filter that can be applied to a surge protection device, which includes an ESD protection function as well as the EMI filter, is provided, such that a process can be simplified and costs can be reduced.

  • Publication number: 20090215259
    Abstract: Disclosed is a semiconductor package and a method of manufacturing the same. The semiconductor package includes a semiconductor chip that includes metal pads provided on a predetermined area of an upper side of a semiconductor substrate, where element structures used to manufacture a semiconductor element are formed, and bump electrodes connected to the metal pads; and a passivation film that is provided on an entire surface of the semiconductor chip other than upper surface of the bump electrodes. Therefore, it is possible to avoid difficulties in performing an epoxy underfill process used in a conventional flip chip bonding, and complexity and high cost resulting from the use of a molding compound process and a solder ball process. It is also possible to prevent damages to the lateral surface of the semiconductor chip due to an absence of the passivation film on the lateral surface of the semiconductor chip in a conventional wafer level package.
