    摘要: A method of manufacturing a non-volatile semiconductor memory device includes forming a sub-gate without an additional mask. A low word-line resistance is formed by a metal silicide layer on a main gate of the memory device. In operation, application of a voltage to the sub-gate forms a transient state inversion layer that serves as a bit-line, so that no implantation is required to form the bit-line.

    摘要: A non-volatile memory device on a semiconductor substrate may include a bottom oxide layer over the substrate, a middle layer of silicon nitride over the bottom oxide layer, and a top oxide layer over the middle layer. The bottom oxide layer may have a hydrogen concentration of up to 5E19 cm−3 and an interface trap density of up to 5E11 cm−2 eV−1. The three-layer structure may be a charge-trapping structure for the memory device, and the memory device may further include a gate over the structure and source and drain regions in the substrate.

    摘要: A NAND-type flash memory device includes asymmetric floating gates overlying respective wordlines. A given floating gate is sufficiently coupled to its respective wordline such that a large gate (i.e., wordline) bias voltage will couple the floating gate with a voltage which can invert the channel under the floating gate. The inversion channel under the floating gate can thus serve as the source/drain. As a result, the memory device does not need a shallow junction, or an assist-gate. In addition, the memory device exhibits relatively low floating gate-to-floating gate (FG-FG) interference.

    摘要: A semiconductor structure with improved capacitance of bit lines includes a substrate, a stacked memory structure, a plurality of bit lines, a first stair contact structure, a first group of transistor structures and a first conductive line. The first stair contact structure is formed on the substrate and includes conductive planes and insulating planes stacked alternately. The conductive planes are separated from each other by the insulating planes for connecting the bit lines to the stacked memory structure by stairs. The first group of transistor structures is formed in a first bulk area where the bit lines pass through and then connect to the conductive planes. The first group of transistor structures has a first gate around the first bulk area. The first conductive line is connected to the first gate to control the voltage applied to the first gate.
