    摘要: A method for manufacturing a semiconductor device including selective conductive contacts includes the step of depositing a resist over first and second memory device components, each of the first and second components comprising junctions formed in the substrate and a gate formed on the substrate between the junctions. The resist is then removed from the second components to thereby form a resist opening above each of the second component control gates and junctions. The resist is then etched to thereby expose each of the first component control gates but not the substrate surrounding the first component control gates. Conductive contacts are then formed on the exposed first component control gates, and the second component control gates and junctions.

    摘要: Device leakage due to spacer undercutting is remedied by depositing a BPSG, SA-CVD oxide liner and flowing it into the undercut regions, followed by gap filling with a P-doped HDP oxide layer. Embodiments include depositing a BPSG, SA-CVD oxide liner containing 4 to 6 wt.% boron, at a thickness of 1,000 Å to 1,800 Å, over closely spaced apart non-volatile transistors and heating during or subsequent to deposition to flow the BPSG, SA-CVD oxide liner into the undercut regions of the sidewall spacers of the gate stacks. Gap filling is then completed by depositing the layer of P-doped HDP at a thickness of 6,000 Å to 10,000 Å.

    摘要: A memory array (25) having a selected memory cell (10) and an unselected memory cell (30) is programmed and read. Each memory cell in the memory array (25) contains an isolation transistor (22) and a floating gate transistor (23). To program the selected memory cell (10), programming voltages are applied to a control gate line (21), a drain line (14), an isolation line (19), and a source line (12). To reduce the effects of the drain disturb problem, a gate terminal (32) of the unselected memory cell (30) is held at a positive voltage. To read selected memory cell (10), a read voltage is applied to an isolation gate line (31) of unselected memory cell (30) which insures that the unselected memory cell (30) does not conduct or contribute to leakage current and power consumption during the read operation.

    摘要: A dual node memory device and methods for fabricating the device are provided. In one embodiment the method comprises forming a layered structure with an insulator layer, a charge storage layer, a buffer layer, and a sacrificial layer on a semiconductor substrate. The layers are patterned to form two spaced apart stacks and an exposed substrate portion between the stacks. A gate insulator and a gate electrode are formed on the exposed substrate, and the sacrificial layer and buffer layer are removed. An additional insulator layer is deposited overlying the charge storage layer to form insulator-storage layer-insulator memory storage areas on each side of the gate electrode. Sidewall spacers are formed at the sidewalls of the gate electrode overlying the storage areas. Bit lines are formed in the substrate spaced apart from the gate electrode, and a word line is formed that contacts the gate electrode and the sidewall spacers.
