Abstract:
PROBLEM TO BE SOLVED: To obtain structure including the level of a conductor being separated by insulation layers that locally cross by a via being filled with metal, by including a stage for performing retching to the level of a surface at the upper side of a sacrifice layer by chemico-mechanical polishing after depositing metallization. SOLUTION: In a method for manufacturing metallization, the thickness of a dielectric layer 38 where the dielectric layer 38 that is made of a material that cannot be etched easily by a prescribed method, is formed on a support is satisfied based on a predetermined pattern. A sacrificial layer 32 with a desired thickness in a material layer is formed on a support 31, an opening 34 is formed at the sacrificial layer 32 based on a determined pattern, and metallization 35 is formed in the opening 34. Then, the sacrificial layer 32 is eliminated, and the layer of a material 37 which at least exceeding a thickness that is equal to that of a metal pattern is deposited, thus applying to a dielectric material that cannot be etched locally to an edge having a sharp slope.

PROBLEM TO BE SOLVED: To increase the number of bits of an analog-to-digital converter without excessively increasing complexity or processing time. SOLUTION: An analog-to-digital conversion method for converting an analog signal into n bits of digital data includes: a comparison step of comparing the amplitude of the analog signal with a threshold obtained by dividing full-scale analog signal amplitude by 2 k ((k) is an integer smaller than (n)); and a step of performing analog-to-digital conversion on the analog signal into n-k bits and obtaining the n-k most significant bits of the n bits of digital data when the result of the comparison step indicates that the amplitude of the analog signal is greater than the threshold, or obtaining the n-k least significant bits of the n bits of digital data when the result of the comparison step indicates that the amplitude of the analog signal is smaller than or equal to the threshold.

PROBLEM TO BE SOLVED: To provide a method of manufacturing a MOS transistor comprising a single crystal semiconductor film with no facets that is formed on a void portion, a laminated structure of single crystal thin films that prevents reduction in the device surface area, and a channel region that has a homogeneous thickness and is separated from an underlying semiconductor wafer by at least one non-single crystal layer with a homogeneous thickness.

PROBLEM TO BE SOLVED: To provide a method and device for controlling a plasma matrix screen in which a sharp drop of column potentials is suppressed. SOLUTION: The method for controlling the plasma matrix screen includes steps of; sequentially selecting rows of the matrix; and, for a selected row, deselecting a plurality of columns of the matrix which were previously selected during the selection of a previous row. To avoid excessive steepness of the falling sections of the column potentials, the previously selected two or more columns are non-simultaneously deselected. COPYRIGHT: (C)2006,JPO&NCIPI
