  • Patent number: 11183509
    Abstract: An approach to use silicided bit line contacts that do not short to the underlying substrate in memory devices. The approach provides for silicide formation in the bit line contact area, using a process that benefits from being self-aligned to the oxide-nitride-oxide (ONO) nitride edges. A further benefit of the approach is that the bit line contact implant and rapid temperature anneal process can be eliminated. This approach is applicable to embedded flash, integrating high density devices and advanced logic processes.

  • Patent number: 10256137
    Abstract: An A method for fabricating an integrated circuit (IC) comprising a substrate, a first device, a second device, and a trench in the substrate is described herein. The trench is self-aligned between the first and second devices and comprises a first portion filled with a dielectric material and a second portion filled with a conductive material. The self-aligned placement of the trench provides electrical isolation between the first and second devices and allows for higher packing density without negatively affecting the operation of closely spaced devices in a high density IC.

  • Patent number: 8102009
    Abstract: An integrated circuit with a semiconductor substrate is provided. A gate dielectric is on the semiconductor substrate, and a gate is on the gate dielectric. A metallic layer is on the semiconductor substrate, and the metallic layer is reacted with the semiconductor substrate to form an early phase of silicide. Implanted shallow source/drain junctions are immediately beneath the silicide. A final phase of the silicide is formed. An interlayer dielectric is above the semiconductor substrate, and contacts are formed to the silicide.
