摘要： A method of forming a metal line, in which a nitride layer is used instead of a metal barrier layer, enabling a metal line structure with a relatively low resistance and therefore realizing a high integration of a device. In the method of forming the metal line of the semiconductor device, a first insulating layer and a second insulating layer with a different etch selectivity are sequentially formed on a semiconductor substrate. Predetermined regions of the first insulating layer and the second insulating layer are sequentially etched to form a contact hole. A metal barrier layer is formed on the entire surface including the contact hole. A first metal material is deposited on the entire surface to gap-fill the contact hole. The first metal material on the second insulating layer is stripped such that the first metal material remains only within the contact hole, thus forming a contact plug. A metal line is formed on a predetermined region of the second insulating layer including the contact plug.

摘要： A chromatic aberration correcting method to correct chromatic aberration generated during a conversion from a reproducing mode to a recording mode in an optical recording and reproducing apparatus which uses an optical pickup to form a light spot on an optical information storage medium by focusing light emitted from a light source using an objective lens and to detect light reflected from the optical information storage medium using a photodetector includes applying a focus offset to the objective lens before the conversion from the reproducing mode to the recording mode to reduce defocus caused by chromatic aberration generated according to the change in wavelength generated when an output light power of the light source is changed from a reproducing light power to a recording light power, and correcting the defocus by outputting the recording light power from the light source during the conversion to the recording mode while the focus offset is applied to the objective lens.
