摘要:
An optical recording medium is provided which has a plurality of recording layers, in which a favorable recording mark can be formed and desired reproduction accuracy can be obtained in any of the recording layers. The optical recording medium has a first recording layer and a second recording layer. In the first and second layers, a recording mark, having an increased thickness larger than that of a neighboring space portion, is formed by an irradiation with a laser beam. The refractive index of the second recording layer placed relatively closer to an incident surface of a laser beam is lower than that of the first recording layer placed farther away from the incident surface of the laser beam than the second recording layer.

摘要:
A multi-layer optical recording medium in which an effect of an interlayer crosstalk can be accurately measured and a method for evaluating a recording system using the same are provided. The multi-layer optical recording medium has a signal intensity measuring region formed in advance such that each recording layer having an identical address is allowed to have a different reflectivity. A signal intensity variation occurring when data recorded on the signal intensity measuring region is reproduced is measured to obtain signal intensity variation information. The method calculates a coherence parameter m describing the coherence of a recording system from the signal intensity variation information and reflectivity information obtained at each of the recording layers without interference from the other recording layers.

A method and apparatus plate a substrate to form wiring by efficiently filling a fine recess formed in a semiconductor substrate with plating metal without a void or contamination. The plating of the substrate to fill a wiring recess formed in the semiconductor substrate with plating metal includes performing an electroless plating process of forming an initial layer on the substrate, and performing an electrolytic plating process of filling the wiring recess with the plating metal, while the initial layer serves as a feeding layer.

A multilayer optical recording medium comprises four recording layers including an L0 layer, an L1 layer, an L2 layer, and L3 layer laminated between a substrate and an optically transparent cover layer and optically transparent spacer layers each provided between the recording layers. The L2 layer has the negative dependence of the reflectance on the incident angle of a laser light beam for reproduction. Crosstalk can be effectively reduced by the relation between the configuration of the respective recording layers and the crosstalk.

A substrate processing apparatus fills a metal such as copper or the like in fine interconnection patterns or trenches defined in a semiconductor substrate. The substrate processing apparatus has a loading/unloading unit for placing a substrate cassette to allow a substrate to be loaded and unloaded, a substrate treating unit for treating a substrate, and a transfer robot for transferring a substrate between the loading/unloading unit and the substrate treating unit. The loading/unloading unit, the substrate treating unit, and the transfer robot are installed in a single facility. The loading/unloading unit has a rotary table which is horizontally rotatable for positioning the substrate cassette in a position to detect the substrate cassette placed in the loading/unloading unit and to remove the substrate from the substrate cassette with the transfer robot.

To obtain an optical recording medium capable of recording at various recording transfer rates from a low speed to a high speed, by using a simple recording strategy.A recording layer 18 of a write-once optical recording medium capable of recording from a low speed to a high speed is formed by laminating a first sub recording layer 18A and a second sub recording layer 18B each containing a metal as its main component. When the recording layer (laminated recording layer) 18 is irradiated with a laser beam having a wavelength equal to or shorter than a blue wavelength by using a recording strategy comprising only a ratio of write power to bias power, the main component metals contained in the first and second sub recording layers 18A, 18B diffuse and are thus mixed together, forming the sub recording layers into a single layer by means of such mixing and forming recording marks whose reflectance have been irreversibly changed. Since the recording mark formation process does not need to select a recording strategy, it is possible to obtain many subordinate advantages such as a variable speed recording.
