摘要:
The etch-back amount of a silicon oxide film of a memory array which is a higher altitude portion is increased when etching back and flattening the silicon oxide film by arranging a first-layer wiring on a BPSG film covering an upper electrode of an information-storing capacitative element only in a peripheral circuit but not arranging it in the memory array. Thus, a DRAM having a stacked capacitor structure is obtained such that the level difference between the memory array and peripheral circuit is decreased, and the formation of wiring and connection holes are easy.

A semiconductor integrated circuit comprising first n-channel MISFETs constituting the memory cells of a storage system, second n-channel MISFETs constituting the peripheral circuits of the storage system, and third n-channel MISFETs constituting the output circuit among the peripheral circuits. The respective threshold voltages of the first n-channel MISFETs, the second n-channel MISFETs and the third n-channel MISFETs are decreased in that order when the respective gate lengths of those MISFETs are substantially the same.

A DRAM has memory cells provided at crossing points between word line conductors and bit line conductors. Each memory cell has a cell selection transistor and an information storage capacitor arranged over the bit line conductors. Unit active regions are defined in a main surface of a semiconductor substrate by a field isolation pattern. The field isolation pattern has a controlled length of extension of bird's beaks so that channel formation regions in each unit active region has almost no stepped portion to provide the cell selection transistors with a stabilized threshold voltage.

In an objective lens for an optical head apparatus for reading or writing an information on a recording medium such as optical disc, astigmatism is added on axial wavefront aberration so that off-axis astigmatism is to be cancelled by the axial astigmatism. At least one surface of the objective lens is a toric or cylindrical surface, and a standard deviation of astigmatism component of axial wavefront aberration is defined as Wa is to be restricted in a range of 0

A semiconductor integrated circuit device having a switching MISFET, and a capacitor element formed over the semiconductor substrate, such as a DRAM, is disclosed. In a first aspect of the present invention, the impurity concentration of the semiconductor region of the switching MISFET to which the capacitor element is connected is less than the impurity concentration of semiconductor regions of MISFETs of peripheral circuitry. In a second aspect, the Y-select signal line overlaps the lower electrode layer of the capacitor element. In a third aspect, a potential barrier layer, provided at least under the semiconductor region of the switching MISFET to which the capacitor element is connected, is formed by diffusion of an impurity for a channel stopper region. In a fourth aspect, the dielectric film of the capacitor element is co-extensive with the capacitor electrode layer over it. In a fifth aspect, the capacitor dielectric film is a silicon nitride film having a silicon oxide layer thereon, the silicon oxide layer being formed by oxidizing a surface layer of the silicon nitride under high pressure. In sixth and seventh aspects, wiring is provided. In the sixth aspect, an aluminum wiring layer and a protective (and/or barrier) layer are formed by sputtering in the same vacuum sputtering chamber without breaking the vacuum between forming the layers; in the seventh aspect, a refractory metal, or a refractory metal silicide QSI.sub.x, where Q is a refractory metal and 0
摘要:
A semiconductor integrated circuit device is equipped with a DRAM whose memory cell is formed as a series circuit of a memory cell selection MISFET and a data storage capacitance element of a stacked structure. A complementary data line extends on an upper electrode layer of the data storage capacitance element of the stacked structure through an inter-level insulation film which is connected to a semiconductor region of the memory cell selection MISFET. To reduce parasitic capacitance the wiring width of the complementary data line is formed to be smaller than the film thickness of the inter-level insulation film between the complementary data line and the upper electrode layer of said data storage capacitance element of the stacked structure.

An information processing apparatus includes circuitry. The circuitry performs ledger sheet recognition on ledger sheet image data, and refers to an association information storage area storing association information representing an output order of a plurality of item values of each of a plurality of item names. The plurality of item values are acquired based on the ledger sheet recognition. The circuitry further generates output data in which the plurality of item values of the each of the plurality of item names are arranged in the output order represented by the association information. The circuitry further outputs the generated output data.
