  • Publication number: 20170125243
    Abstract: Provided are a novel amino-silyl amine compound and a manufacturing method of a dielectric film containing Si—N bond using the same. Since the amino-silyl amine compound according to the present invention, which is a thermally stable and highly volatile compound, may be treated at room temperature and used as a liquid state compound at room temperature and pressure, the present invention provides a manufacturing method of a high purity dielectric film containing a Si—N bond even at a low temperature and plasma condition by using atomic layer deposition (PEALD).

  • Patent number: 8048483
    Abstract: A method to deposit a thin film on a flexible polymer substrate at room temperature comprising heating source vapor, which is vaporized by an evaporator, in a shower head in a reaction chamber so that the source vapor is thermally decomposed to be converted into the nano-size single phase; and depositing the source vapor in the nano-size single phase on the flexible polymer substrate which is not separately heated.

  • Patent number: 7088707
    Abstract: A method is used for setting a R-P link for data transmission/reception in a mobile communication system and for setting a R-P link between packet control function (PCF) and packet data serving node (PDSN) in a mobile communication system that connects a radio network with a packet network. The method first transmits a response request message from the PCF to identify the status of two or more PDSNs in the system, then measures the RTDs of those PDSNs responded to the response request message. The method subsequently prepares a list of PDSNs that satisfy a reference value among the measured RTDs and determines whether the subscriber's PDSN exists in the list of PDSNs. Finally, the method performs a R-P link setup using the prepared list of PDSN in accordance with a determined result.

  • Publication number: 20030227921
    Abstract: A system and method for controlling a data call traffic frame in a mobile communication system assigns a sequence number to the traffic frame transmitted and received between the SDU and the PCF. This allows for a lost traffic frame to be easily detected. Because lost traffic frames can be detected and re-transmitted between the SDU and PCF, the lost traffic frame can be restored without using a radio section. Thus, transmission reliability between the SDU and PCF can be improved and a waste of radio resources can be prevented.
