    Abstract: Methods of manufacturing are provided. In one aspect, a method of manufacturing is provided that includes forming first and second gate stacks on a substrate and forming an insulating layer on the substrate. The insulating layer has portions adjacent to the first stack and portions adjacent to the second gate stack. A first pair of insulating structures is formed adjacent to the first gate stack and a second pair of insulating structures is formed adjacent to the second gate stack. The first pair of insulating structures is removed. The portions of the insulating layer adjacent to the first gate stack are thickened while the second pair of insulating structures prevents thickening of the portions of the insulating film adjacent to the second gate stack. Differential insulating layer thickness for different gate devices is permitted to enable reduction in leakage currents for selected devices without harming speed performance for others.

    Abstract: In a semiconductor device including a first conductive layer, the first conductive layer is treated with a nitrogen/hydrogen plasma before an additional layer is deposited thereover. The treatment stuffs the surface with nitrogen, thereby preventing oxygen from being adsorbed onto the surface of the first conductive layer. In one embodiment, a second conductive layer is deposited onto the first conductive layer, and the plasma treatment lessens if not eliminates an oxide formed between the two layers as a result of subsequent thermal treatments. In another embodiment, a dielectric layer is deposited onto the first conductive layer, and the plasma treatment lessens if not eliminates the ability of the first conductive layer to incorporate oxygen from the dielectric.

    Abstract: A new method to form ROM devices in the manufacture of an integrated circuit device is achieved. The method comprises providing a semiconductor substrate. MOS gates are formed overlying the substrate. Ions are implanted into the substrate to form lightly doped drains for the MOS gates. A masking layer is used to offset the lightly doped drains from selective MOS gates to thereby form constant-OFF MOS gates. Spacers are next formed on the sidewalls of the MOS gates. Finally, ions are implanted into the substrate to form source and drain regions for the MOS gates to thereby complete the ROM devices in the manufacture of said integrated circuit device. The method may be extended to form ROM devices from Flash gates in a FlashROM process.
