Patent number: 8154083Abstract: The present invention relates to a semiconductor device and a method of manufacturing the same. A high-resistance silicon wafer is manufactured in such a manner that a large-sized silicon wafer manufactured by the Czochralski method is irradiated with neutrons, and high-resistance and low-resistance elements are simultaneously formed on the high-resistance silicon wafer. Thus, the manufacturing cost can be remarkably saved, and the reliability of products can be enhanced.Type: GrantFiled: January 21, 2011Date of Patent: April 10, 2012Assignee: Petari IncorporationInventor: Young Jin Park

Publication number: 20110163412Abstract: The present invention relates to an isolator and a method of manufacturing the same. An isolator according to the present invention includes a silicon wafer, protective devices formed in predetermined regions of the silicon wafer, and a transformer formed in a predetermined region on the silicon wafer, the transformer having at least two coil patterns spaced apart from each other. According to the present invention, an isolator can be protected from impulses generated by ESD and surge, so that its reliability can be improved, and its size can be considerably decreased. Further, the number of wire bonding times is decreased, so that performance of a chip can be enhanced, and packaging efficiency can be improved, thereby increasing productivity.Type: ApplicationFiled: January 12, 2011Publication date: July 7, 2011Applicant: PETARI INCORPORATIONInventor: Young Jin PARK

Patent number: 7825750Abstract: 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.Type: GrantFiled: June 27, 2007Date of Patent: November 2, 2010Assignee: Petari IncorporationInventors: Kye Nam Lee, Young Jin Park, Jin Hyung Kim, Hyun Kyu Yang, Yoo Ran Kim

Publication number: 20090215259Abstract: 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.Type: ApplicationFiled: April 3, 2009Publication date: August 27, 2009Applicants: PETARI INCORPORATIONInventors: Kye Nam LEE, Young Jin PARK, Hyun Kyu YANG, Yoo Ran KIM
