    Abstract: PURPOSE:To provide a manufacture of a semiconductor device which can increase the threshold of a parasitic transistor to the MOS transistor in a memory region, without increasing the number of masks. CONSTITUTION:LOCOS 12 is made on the surface of a semiconductor substrate 2, and then the first polysilicon film 18 to serve as a floating gate is formed, and then ions for channel stopper are implanted below the LOCOS 12, using a resist film 20 for processing the pattern of the first polysilicon film 18 as a mask, so as to form the second channel stopper region. The breakdown strength can also be improved by forming the same first channel stopper region 14 as before together with the second stopper region, in the specified transistor of a peripheral circuit S.

    Abstract: PURPOSE:To fabricate a semiconductor device that does not have a leak path which substantially brings about a leakage on side walls of a contact section to be formed on the diffused layer of a Si substrate by installing the side wall made of at least three-layered insulating film in the contact opening section. CONSTITUTION:A side wall section formed on a diffused layer 12 of a silicon substrate 11, in addition to a BPSG-film side wall 18, has a three-layer side wall 30 consisting of a nitriding film 16a and a PSG film 15a. Thus, the side wall 30 has a three-layer structure. With this, even when a leak path 21 is produced on the side wall 18 of BPSG film which is the surface of the side wall 30, the leak path is not extended to the adjacent nitriding layer 16a, but stays only on one layer of the side wall 18. Accordingly, the leak path is not substantially extended to a gate electrode 13 and a diffused layer 12, causing a leak problem. Namely, a leak path that substantially brings about a leakage can be eliminated.

    Abstract: PURPOSE:To prevent the escape of electrons from a floating gate of a nonselected call at the time of writing without reducing erasing characteristics by increasing in thickness an end of a gate oxide film at the side of a drain between the gate and a channel. CONSTITUTION:A gate oxide film 4 between a channel and a floating gate is formed to be thicker at an end 4a of a drain side than the other part in a two-layer gate type semiconductor device. Accordingly, since the end 4a of the drain side is thicker than the other part, an electric field intensity of an end of the film 4 at the side of the drain 2 when nonselected at the time of writing is weakened. Therefore, electrons scarcely escape from a floating gate 5. That is, escape of the electrons from the gate of nonselected cell at the time of writing can be prevented without reducing erasing characteristics.

    Abstract: PROBLEM TO BE SOLVED: To attract many free and charged users to a community and to charge a price corresponding to an application state to each charged user while maintaining action in the community. SOLUTION: Although login to the community is not charged, an item or a function for providing a differential factor to a user in community service is charged. Since the login itself is maintained free of charge, each user can join the community without hesitation, so that the number of participants is increased and the community itself is formed. Since a property that items or functions should be optionally prepared by each user is strong, there is no objection or incompatibility in almost of users with respect to charging.

    Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent what is called 'disguise' at the time of the communications of simple money amount replenishing data, by comparing a random number added to reception data with a random number generated by itself and treating reception data as the right one only at the time of coincidence. SOLUTION: A user management function block 110 calculates new security ID to the player based on random number generation in a security ID generating function part 115 and, moreover, a control function part 111 enciphers security ID together with point information. Enciphering at this time is also executed by using a session key, which is previously transmitted from the player. Thus, the random number is generated whenever data exchange is executed with a communication opposite party, the random number is added to transmission data at the time of transmitting data, the random number added to reception data is compared with the one generated at this side in a data reception side and, then, reception data is treated as the right one only at the time of coincidence.

    Abstract: PURPOSE:To moderate concentration of an electric field between a drain diffusion layer and a channel stopper by a method wherein a boundary part between the drain diffusion layer and an element isolation region is covered with a conductive film. CONSTITUTION:A boundary part of an Si substrate 11 between an element isolation region 12 and a drain diffusion layer 16 is so made as to be covered with a conductive film 14b. The conductive film 14b has a potential equal to the one of the drain diffusion layer 16 and, besides, the conductive film 14b is formed of the same layer as that of a gate electrode 14a. Moreover, the drain diffusion layer 16 is formed with the conductive film 14b used as a part of a mask and thereby a channel stopper 21 of the element isolation region 12 is separated from the drain diffusion layer 16. According to this constitution, concentration of an electric field between the drain diffusion layer 16 and the channel stopper 21 can be moderated. In addition, the conductive film 14b is patterned more easily than the channel stopper of low concentration formed only in the vicinity of the boundary part of the element isolation region 12 between this region and the drain diffusion layer 16.
