  • Patent number: 8035136
    Abstract: In a semiconductor device and a method of manufacturing the same, a substrate is defined into active and non-active regions by a device isolation layer and a recessed portion is formed on the active region. A gate electrode includes a gate insulation layer on an inner sidewall and a bottom of the recessed portion, a lower electrode on the gate insulation layer and an inner spacer on the lower electrode in the recessed portion, and an upper electrode that is positioned on the inner spacer and connected to the lower electrode. Source and drain impurity regions are formed at surface portions of the active region of the substrate adjacent to the upper electrode. Accordingly, the source and drain impurity regions are electrically insulated by the inner spacer in the recessed portion of the substrate like a bridge, to thereby sufficiently prevent gate-induced drain leakage (GIDL) at the gate electrode.

  • Patent number: 7327610
    Abstract: A memory layout where the pre-charger circuits are connected between different pairs of bit lines than are the sense amplifiers: The two bits lines in each bit line pair are connected to different pre-charge circuits and thus they can be charged to different pre-charge voltages. That is, the bit line and bit line bar sense lines in each bit line pair are connected to different pre-charge circuits. With this configuration it is possible to perform a sense stress test by activating all of the address lines at the same time and to charge to bit line and the bit bar line in each pair of sense lines to different voltages. With this configuration it is possible to reduce the number of test pads required.
