Abstract: PURPOSE: A system and a method for synchronization of clock and frequency using a satellite are provided to realize a reference clock required for synchronization of a communication network using a satellite link, facilitating synchronizing of clock and frequency. CONSTITUTION: The system includes a transmitter(110), receivers(120-12n) and at least one monitoring and correcting device(130-13n). The transmitter generates clock and frequency synchronizing signals using an atomic clock, accidents monitoring information and satellite orbit information to transmit satellite orbit data, correction data and clock information to a geostationary orbit satellite. The receivers receive a signal sent from the geostationary orbit satellite, that was delayed and distorted on a satellite link, to recover clocks for synchronizing the clock and frequency. The monitoring and correcting device measures the amount of distortion on the satellite link in real time, senses accidents and sends the sensed information to the transmitter.

Abstract: PURPOSE: A method for forming a contact hole of a semiconductor device is provided to prevent generation of leakage current from a gate electrode to an adjacent contact. CONSTITUTION: In the method, a conductive layer(69) and the first insulating layer(70) are formed on a semiconductor wafer(50), and then a nitride layer(72) is formed thereon to protect the underlying layers(69,70) in a subsequent etching process. The nitride layer(72), the first insulating layer and the conductive layer(69) are then selectively etched to form the gate electrode(74). Next, the second insulating layer is formed over the wafer(50) and then etched to form a spacer(76) on a sidewall of the gate electrode(74). Thereafter, an interlayer dielectric layer(80) is formed over the wafer(50) and then anisotropically etched by using a mixed gas to form the contact hole(79). In the mixed gas, an etch rate of the interlayer dielectric layer(80) to the nitride layer(72) is 5 - 15:1. Therefore, damage of the gate electrode(74) is prevented due to the nitride layer(72) having a lower etch rate and thereby leakage current is prevented.
