Abstract: The speed of a vehicle is automatically controlled in a speed bump area located in the vicinity of a speed bump. Information about a speed bump is received from a navigation device, and a distance between the vehicle and the speed bump is calculated. If the calculated is less than a preset reference distance, it is determined that the vehicle is entering or has entered an area of the speed bump. Upon determining that the vehicle is in the speed bump area, a speed difference between a safe speed bump crossing speed and a current speed of the vehicle is computed, a required acceleration value is calculated based on the calculated distance to the speed bump and the speed difference, and the speed of the vehicle is controlled so that the vehicle decelerates or accelerates in accordance with the required acceleration value.

Abstract: In a deposition apparatus, as a plurality of plasma connection terminals that transfer plasma power to a plasma electrode are coupled in parallel to the plasma electrode, resistance caused by the plurality of plasma connection terminals is reduced and a current is distributed such that heat generated in the plurality of plasma connection terminals can be distributed. Therefore, even if high RF power is used, by preventing the plurality of plasma connection terminals from being oxidized, plasma is stably supplied and thus, stability of a deposition apparatus and the accuracy of a process can be enhanced.

Abstract: A thin film deposition apparatus including a substrate mounting error detector, a chamber and a substrate support positioned in the chamber. The substrate support is configured to support a substrate. The substrate mounting error detector includes: a light source configured to provide a light beam to the substrate, such that the substrate reflects the light beam; a collimator configured to selectively pass at least a portion of the light beam reflected by the substrate; and an optical sensor configured to detect the at least a portion of the reflected light beam passed by the collimator. The detector is positioned and oriented to detect substrate position on a lowered support prior to raising the support into contact with an upper cover of a clamshell reactor arrangement. This configuration allows a thin film deposition process only if the substrate is correctly mounted on the substrate support. Thus, abnormal deposition due to a substrate mounting error is prevented in advance.

Abstract: The present invention relates to an ALD apparatus, and particularly relates to an ALD apparatus that is suitable for rapidly depositing a thin film on a substrate having an actual area that is larger than a planar substrate. In the reaction chamber of the ALD apparatus according to an exemplary embodiment of the present invention, more gas is supplied to a portion where more gas is required by having differences in the space for gas to flow rather than supplying the gas in a constant flux and a constant flow velocity such that the time required for supplying reactant gases and waste of reactant gases may be minimized to increase productivity of the ALD apparatus. The ceiling of the reaction space is shaped to provide a nonuniform gap over the substrate.
