  • Patent number: 7494885
    Abstract: According to one exemplary embodiment, a method for forming a field effect transistor on a substrate comprises a step of forming disposable spacers adjacent to a gate stack situated on the substrate, where the disposable spacers comprise amorphous carbon. The disposable spacers can be formed by depositing a layer of amorphous carbon on the gate stack and anisotropically etching the layer of amorphous carbon. The method further comprises forming source and drain regions in the substrate, where the source and drain regions are situated adjacent to the disposable spacers. According to this exemplary embodiment, the method further comprises removing the disposable spacers, where the removal of the disposable spacers causes substantially no gouging in the substrate. The disposable spacers can be removed by using a dry etch process. The method can further comprise forming extension regions in the substrate adjacent to the gate stack prior to forming the disposable spacers.

  • Patent number: 7378310
    Abstract: A method for manufacturing a memory device having a metal nanocrystal charge storage structure. A substrate is provided and a first layer of dielectric material is grown on the substrate. A layer of metal oxide having a first heat of formation is formed on the first layer of dielectric material. A metal layer having a second heat of formation is formed on the metal oxide layer. The second heat of formation is greater than the first heat of formation. The metal oxide layer and the metal layer are annealed which causes the metal layer to reduce the metal oxide layer to metallic form, which then agglomerates to form metal islands. The metal layer becomes oxidized thereby embedding the metal islands within an oxide layer to form a nanocrystal layer. A control oxide is formed over the nanocrystal layer and a gate electrode is formed on the control oxide.
