  • Patent number: 8789002
    Abstract: A method of manufacturing a semiconductor device on the basis of changed design layout data. The method decides a functional relationship between layout parameters based on layout data and the electrical characteristic of a plurality of semiconductor elements. Candidates of the values of the layout parameters are extracted from design layout data so as to decrease the difference between a target electrical characteristic and a predicted electrical characteristic. A specific value from the candidate values of the layout parameters is selected and the design layout data is changed based on the specific selected value.

  • Patent number: 8084844
    Abstract: A semiconductor device in which potential is uniformly controlled and in which the influence of noise is reduced. A p-type well region is formed beneath a surface of a p-type Si substrate. n-type MOS transistors are formed on the p-type well region. An n-type well region is formed in the p-type Si substrate so that it surrounds the p-type well region. A plurality of conductive regions which pierce through the n-type well region are formed at regular intervals. By doing so, parasitic resistance from the p-type Si substrate, through the plurality of conductive regions, to the n-type MOS transistors becomes low. Accordingly, when back bias is applied to a contact region, the back bias potential of the n-type MOS transistors can be controlled uniformly. As a result, the influence of noise from the p-type Si substrate or the p-type well region can be reduced.

  • Patent number: 7852655
    Abstract: Disclosed is a semiconductor memory device capable of realizing reduction in an SRAM unit cell area. Using as a standard configuration a parallel-type SRAM unit cell having each pair of load transistors, driver transistors and transfer transistors, all or a part of the gate electrodes and active regions configuring at least any one of the pairs of the transistors, for example, the pair of the transfer transistors are configured obliquely in a predetermined direction from the standard configuration. As a result, a size in a cell outside part including the driver transistor and the transfer transistor is reduced. At the same time, a distance between the load transistors in the central part is reduced as compared with that in the standard configuration. Thus, area reduction in the whole SRAM unit cell is realized.

  • Patent number: 7579246
    Abstract: An active region and an opposite conductivity active region are formed in a semiconductor substrate. The opposite conductivity active region is covered with a resist pattern. Impurities are implanted into a surface layer of the active region. An angle ?0 is defined as a tilt angle obtained by tilting a virtual plane perpendicular to the substrate and including an edge of the active region, toward the resist pattern by using as a fulcrum a point on the substrate nearest to the resist pattern, until the virtual plane contacts the resist pattern. The ion implantation is performed in a direction having a tilt angle larger than ?0 and allowing ions passed through the uppermost edge of the resist pattern to be incident upon an area between the resist pattern and the active region, and is not performed along a direction allowing the ions to be incident upon the active region.
