    摘要: In the method for fabricating a semiconductor device of the present invention, a collector layer of a first conductivity type is formed in a region of a semiconductor substrate sandwiched by device isolation. A collector opening is formed through a first insulating layer deposited on the semiconductor substrate so that the range of the collector opening covers the collector layer and part of the device isolation. A semiconductor layer of a second conductivity type as an external base is formed on a portion of the semiconductor substrate located inside the collector opening, while junction leak prevention layers of the same conductivity type as the external base are formed in the semiconductor substrate. Thus, the active region is narrower than the collector opening reducing the transistor area, while minimizing junction leak.

    摘要: An array of non-volatile memory cells arranged in rows and columns is provided. Each memory cell is composed of a transistor made up of a gate, a source, and drain and a capacitance section. Each memory cell is connected to a row decoder through a wordline, to a column decoder through a bitline, and to a source decoder through a sourceline. Arranged in a path extending from a bitline to a sourceline through a transistor is an anisotropic resistance section, e.g., a diode, exhibiting different voltage-current characteristics for different levels of voltages applied thereacross. Because of such arrangement, leakage current occurring to a deselected memory cell in a reading operation can be reduced or can be eliminated. Read errors due to leakage current can be avoided and the power consumption can be reduced.

    摘要: A surface region of a P-type semiconductor substrate is defined by an isolation into plural active regions at which a semiconductor element is to be formed. A first diffusion region such as a drain region, a second diffusion region such as a source region, and a wiring member such as a word line are arranged at each active region. The surface of the word line is covered with a first insulating layer. A second insulating layer is provided, in which a region including in common each overhead region on at least two second diffusion regions is removed, leaving an overhead region on the first diffusion region. Provided above the second diffusion region is a conductive member such as a capacity storage electrode, a bit line. A contact member which connects the conductive member and the second diffusion region is formed at a region where the second insulating layer is removed. With the second insulating layer of such configuration, an increase in connection resistance and a connection defect of the capacity storage electrode contact or the bit line contact are prevented.
