Abstract: PURPOSE: A method for fabricating a semiconductor device is provided to improve a gap-fill property of interlayer dielectrics and to obtain a process margin in a self align contact process. CONSTITUTION: Firstly, a gate oxide(12), the first polysilicon layer(13), a tungsten silicide layer(14) and mask layer(15) are successively formed on a semiconductor substrate(11), and then etched to form gate electrodes. Next, spacers(16) are formed on sidewalls of the gate electrodes, and junction regions(17) are selectively formed in the substrate(11). Particularly, the mask layer(15) has a thinner thickness from 500 to 1000 angstrom, effecting an improvement of a gap-fill property. After that, the first interlayer dielectric(18) is formed enough to fill gaps between the adjacent gate electrodes without voids, and then a barrier(19) is formed and patterned thereon. Thereafter, the second interlayer dielectric(20) is formed, and a self align contact process is performed to form contact holes exposing the junction regions(17). The second polysilicon layer(21) is then filled in the contact holes, and the layers(21,20,19) above the first interlayer dielectric(18) are wholly removed.

Abstract: PURPOSE: A receiving device for quick cells is provided to reduce an execution time and a calculation amount of a cell searching procedure for searching a target base station, when UEs(User Elements) are handoffed to other target base stations. Therefore, a handoff process to the target base station is quickly completed. CONSTITUTION: The first step of detecting a slot start time point comprises the steps as follows. A receiving device receives a signal from a target base station. The received signal is divided into an I(Inphase) channel signal and a Q(Quadrature) channel signal, and carriers are removed. Each of the carriers-removed I/Q channel signals passes through pulse forming filters(110,120), and passes through interface filters(130,140). The interface filters(130,140) take correlations relating to receiving signals by using an OGC(Orthogonal Gold Code)(Cp), and transmit results to square circuits(150,160). The square circuits(150,160) sum up each squared correlation result value and store the values. Each correlation result value is stored in a slot sum block(170) with slot units. The slot-unit correlation result values are compared with a specific preset threshold value. A slot in which a maximum correlation result value is detected is decided as the slot start time point of each frame, among slots in which correlation result values exceeding the threshold value are deducted. If the correlation result values exceeding the threshold value are not deducted, the first step of detecting the slot start time point is repeated.

Abstract: PURPOSE: A method for adjusting a speed for an optical disk is provided to adjust speed suitable for an unblanced disk. CONSTITUTION: A number of track-crossing due to eccentricity is measured and stored after rotating a disk at a predetermined speed. A number of track-crossing due to vibration is measured and stored after rotating the disk at a higher speed than the predetermined speed. A speed for an optical disk is adjusted based on a difference between the number of track-crossing due to eccentricity and that due to vibration. When measuring the number of track-crossing due to vibration, the number of track-crossing is measured at first time at a higher speed than the predetermined speed, and then the number of track crossing is measured at second time at a higher speed than that performed at the first time. If a difference between the number of track-crossing measured at the second time and the stored number of track-crossing is lesser than a pre-set reference value, the speed for the optical disk is upwardly adjusted.
