Abstract: A fastener, for use with a sheet-shaped member, comprises a tubular shank, a plurality of holding pieces extending outward from a first end of the shank, a flange extending outward from a second end of the shank, and a plurality of stud-engagement pawls extending into the interior of the shank. The shank has a length less than that of a stem of a stud fixed to a mounting member with which the fastener is to be engaged. When the stud is fully inserted into the tubular shank, the sheet-shaped member is fastened to the stud and the stud stem protrudes from a surface of the sheet-shaped member. The protruding portion of the stem allows an auxiliary member to be mounted thereto.

Abstract: A method for designing a logic circuit and a CAD program which allow a logic circuit with desired performance to be designed in a short period of time by suppressing the elongation of a logic design period for achieving a circuit area, an operating speed, power consumption, and the like as target specifications are provided at low cost. Shorter-period and lower-cost design is accomplished by allowing a user to use a high-performance logic synthesis CAD program at no charge if he only checks circuit characteristics resulting from synthesis and collecting a fee if the user is satisfied with the resulting circuit characteristics and intends to use a gate level logic circuit. In a design phase which receives a register transfer level or operation level logic circuit and synthesizes a gate level logic circuit, desired circuit characteristics are obtainable in a short period of time at low cost.

Abstract: Mutual diffusion of impurities in a gate electrode is suppressed near a boundary between an n-channel type MISFET and a p-channel type MISFET, which adopt a polycide's dual-gate structure. Since a gate electrode of an n-channel type MISFET and a gate electrode of a p-channel type MISFET are of mutually different conductivity types, they are separated to prevent the mutual diffusion of the impurities and are electrically connected to each other via a metallic wiring formed in the following steps. In a step before a gate electrode material is patterned to separate the gate electrodes, the mutual diffusion of the impurities before forming the gate electrodes is prevented by performing no heat treatment at a temperature of 700° C. or higher.

Abstract: When a non-volatile memory write error occurs in a card storage device containing a non-volatile memory and an error correction circuit, write data is read from the non-volatile memory and a check is made if the error can be corrected by the error correction circuit. If the error can be corrected, the write operation is ended. If the error correction circuit cannot correct the error, substitute processing is performed to write data into some other area.

Abstract: The production of semiconductor devices manufactured through a plurality of manufacturing sites is unitarily managed and an appropriate production plan is instructed. A computer projects a production plan of an entire company based on various information. The production plan is provided to each manufacturing site as a production instruction and provided to each business person or customer as a storing reply or an order accepting period reply. If the projected production plan (possible production volume) does not coincide with a production plan (necessary production volume), parameters obtained by correcting production allocation, production capability, lead time, yield and the like are re-input from a parameter input terminal. Based on the corrected parameters, the computer re-projects the production plan and projects an optimum production plan.

Abstract: Defects in element forming regions on which memory cells of a non-volatile memory are formed are to be diminished to reduce leakage current. End portions of element forming regions with non-volatile memory cells formed thereon are extended a length D by utilizing the region which underlies a dummy conductive film, whereby a stress induced from an insulating film which surrounds the element forming regions is concentrated on the extended region. As a result, defects do not extend up to the regions where memory cells are formed and therefore it is possible to reduce leakage current in the memory cells.

Abstract: In order to test whether a given signal of a complex circuit has the correct behavior, a method is provided which makes it possible to obtain in a computer memory a profile of states of other signals. In order to minimize the processing time and the memory space required to obtain this profile, the method uses two binary decision diagrams starting with a binary variable of said one signal, each with two binary decision subdiagrams. The method combines the binary decision subdiagrams so that the given signal is in a first state when the binary variable is at a first value and is not in this first logical state when the binary variable is at a second value.
