    • PURPOSE: To reduce unevenness of a threshold voltage of a MISFET or MISFET pair for constituting, for example, a sense amplifier. CONSTITUTION: In a logic circuit region having a logic circuit necessary to drive a memory cell such as a sense amplifier circuit or the like, n-type active regions nw1, nw2 not having a gate electrode are disposed at both ends of active regions (nwp1, nwp2) having p-channel MISFET pair for constituting the sense amplifier, and (L4-L5), (L6-L5) and (L4-L6), wherein L4 is the distance between the region nwp1 and the region nw1, L6 is the distance between the region newp2 and the region nw2, and L5 is the distance between the region nwp1 and the region nwp2, are set substantially '0' or less than twice a minimum processing size. As a result, the unevenness of the shape of an element isolation groove in the L4, L5 and L6 is reduced, and a threshold voltage difference of the MISFET pair can be suppressed.
    • 目的:减少用于构成例如读出放大器的MISFET或MISFET对的阈值电压的不均匀性。 构成:在具有驱动诸如读出放大器电路等的存储单元所必需的逻辑电路的逻辑电路区域中,在有源区(nwp1)的两端设置不具有栅电极的n型有源区nw1,nw2 ,(L4-L5),(L6-L5)和(L4-L6),其中L4是区域nwp1和区域nw1之间的距离,L6是 区域newp2和区域nw2之间的距离,以及L5是区域nwp1和区域nwp2之间的距离,被设置为基本上为“0”或小于最小处理大小的两倍。 结果,L4,L5和L6中的元件隔离槽的形状不均匀性降低,并且可以抑制MISFET对的阈值电压差。

    • PURPOSE: To provide a dynamic RAM of single-intersection type, where an operation margin is improved, and to provide a semiconductor device. CONSTITUTION: A dynamic RAM has a plurality of word lines connected to the address selection terminals of a plurality of dynamic memory cells, a plurality of complementary bit line couples connected to respective input/output terminals of the dynamic memory cells and are arranged in mutually opposite directions and a sense amplifier string formed of a plurality of latch circuits, to which operation voltage is given corresponding to the operation timing signal and amplifies the voltage difference of the complementary bit line pairs. Common electrodes installed by making them face an accumulation node being the connection point of address selective MOSFET of the dynamic memory cells installed on both sides with the sense amplifier string as a center and an information storage capacitor are mutually connected, while circuit connections in the sense amplifier string are secured by a wiring means using the electrodes. Thus, complementary noise, generated in the two plate electrodes installed across the sense amplifier string, is canceled and is substantially reduced.
