    摘要: Within a first of a pair of methods for forming a memory cell structure there is employed a sacrificial spacer layer formed adjacent a capacitor structure and subsequently stripped therefrom to provide an air gap void interposed between a bitline stud layer and the capacitor structure. Within a second of the pair of methods for forming a memory cell structure there is employed a topographically variable thickness masking layer as a self aligned mask layer for forming a patterned capacitor plate layer from a topographic blanket capacitor plate layer. The methods provide for readily forming the memory cell structure with enhanced performance.

    摘要: A voltage limiting isolation circuit for pairs of bit lines within a row of DRAM cells to reduce noise coupling will selectively connect and disconnect the portions of a primary and a complementary bit lines, onto which DRAM cells are attached, from the portions of the primary and the complementary bit lines, onto which latching sense amplifier and pre-charge and equalization circuit are attached. The voltage limiting bit line isolation circuit has two sets of serially connected N-type MOS transistors and first P-type MOS transistors placed on the primary bit line and the complementary bit line. Isolation voltage control circuits will provide voltages to the gates of the N-type MOS transistors and P-type MOS transistors to activate and deactivate the voltage limiting isolation control circuit. During a read cycle the latching sense amplifier will sense and amplify the charge from a selected cell and begin to force the first and second portions of the primary and complementary bit lines to a voltage level that is either that of the power supply voltage source or the ground. As the voltage level of the first and second portions of the primary and complementary bit lines approaches to within one threshold voltage level of the MOS transistors, the voltage limiting bit line isolation circuit will deactivate. The first portions of the primary and complementary bit lines will swing to a lower voltage level thus lowering coupled noise to adjacent bit lines.

    摘要: A semiconductor device is prepared by an annealing process to interconnect at least two components of the device by a conductor line surrounded by an insulator material. The annealing process results in formation of residual stresses within the conductor line and the insulator material. A notch is designed in the layout on a selective portion of the mask for patterning conductor line. The existence of a shape of notch on the selective portion generates extra stress components within the conductor line than if without the existence of the notch. The position of the notch is selected so that the extra stress components substantially counteract the residual stresses, thereby causing a net reduction in the residual stresses. The reduction in the residual stresses results in a corresponding mechanical stress migration and therefore improvement in the reliability of the device.

An offset spacer is formed on sidewalls of the gate dielectric layer and the gate electrode layer. A carbon spacer is formed on a sidewall of the offset spacer, and the carbon spacer is then removed. The substrate is implanted to form a lightly doped region using the gate electrode layer and the offset spacer as a mask. The method may also include providing a substrate having a gate dielectric layer and a gate electrode layer sequentially formed thereon. A liner layer is formed on sidewalls of the gate electrode layer and on the substrate. A carbon spacer is formed on a portion of the liner layer adjacent the sidewall of the gate electrode layer. A main spacer is formed on a sidewall of the carbon spacer. The carbon spacer is removed to form an opening between the liner layer and the main spacer. The opening is sealed by a sealing layer to form an air gap.
