摘要： An image recognition apparatus recognizes the correspondence between character strings and logical elements composing a logical structure in an image in which the character strings are described as the logical elements to recognize each logical element. The image recognition apparatus includes outputting means for outputting the recognized logical elements when the correspondence is recognized or re-recognized; first determining means for determining a certain logical element to be correct when input of a determination request to determine the logical element is received from a user; second determining means for determining the correctness of all the logical elements output before the logical element determined by the first determining means and is positioned according to confirmation by the user; and re-recognizing means for re-recognizing the correspondence between logical elements that have not been determined to be correct and the character strings on the basis of the determination content for each logical element.

摘要： Matching between a reference image and an input image is performed without relying on specific elements such as line segments or tables. An edge image is generated from the reference image and divided into small blocks, and search range and search priority of each small block are determined and stored in a storage device. When an input image is input, an edge image thereof is generated. The small blocks in the reference image are retrieved in order of priority, and matching with the input image is judged. When the corresponding position of one small block is determined, the search range and search priority for other small blocks not yet judged for matching are updated on the basis of the determined corresponding position.

摘要： A plasma etching apparatus includes a process chamber that can be set at a reduced pressure. A lower electrode on which a semiconductor wafer is placed and an upper electrode opposing the lower electrode are disposed in the process chamber. The lower and upper electrodes are connected to RF power supplies, respectively. First and second RF powers, the phases and power ratio of which are separately controlled, can be applied to the upper and lower electrodes. Parameters including the frequencies, power values, and relative phases of the first and second RF powers are selected in order to set the etching characteristics, e.g., an etching rate, the planar uniformity of the etching rate, the etching selectivity ratio and the like to predetermined values. During etching, the first and second RF powers are monitored by separate detectors, and are maintained at initial preset values through a controller.

摘要： The present invention provides a dry etching method for achieving a satisfactory anisotropic etching of, for example, a semiconductor wafer, particularly, a polysilicon layer formed on the wafer. In the present invention, a mixed gas comprising a first gas containing Br and a second gas containing a halogen element other than Br, e.g., a mixed gas consisting of a HBr gas and a HCl gas, is introduced into a vacuum chamber. The mixed gas is converted into plasma by applying a high frequency power to an upper electrode 5. The plasma region is irradiated, as desired, with an ultraviolet light. The semiconductor wafer is etched with the plasma. The etching is carried out under optimum conditions. For example, the surface temperature of the semiconductor wafer, i.e., workpiece, is maintained at a level falling within a range of between 70.degree. C. and 120.degree. C. Also, the flow rate ratio of the mixed gas is suitably controlled.

摘要： A workpiece is etched with a plasma. First, a chamber is provided in which a pair of electrodes are arranged parallel to each other at a distance. The electrodes define a plasma generation area therebetween. The workpiece is arranged in the chamber. The chamber is evacuated, and a desired plasma generation gas is introduced into the plasma generation area. Light having a wavelength of not more than 436 nm is radiated onto the gas in the plasma generation area for a predetermined period of time. Then, a high-frequency power is applied across the electrodes to generate a plasma from the plasma generation gas. The workpiece is etched with the generated plasma.
