  • Patent number: 9583393
    Abstract: Embodiments of mechanisms for epitaxially growing one or more doped silicon-containing materials to form source and drain regions of finFET devices are provided in this disclosure. The dopants in the one or more doped silicon-containing materials can be driven into the neighboring lightly-doped-drain (LDD) regions by thermal anneal to dope the regions. The epitaxially growing process uses a cyclical deposition/deposition/etch (CDDE) process. In each cycle of the CDDE process, a first and a second doped materials are formed and a following etch removes most of the second doped material. The first doped material has a higher dopant concentration than the second material and is protected from the etching process by the second doped material. The CDDE process enables forming a highly doped silicon-containing material.

  • Patent number: 9306024
    Abstract: A semiconductor device and methods of formation are provided. A semiconductor device includes a dielectric film over a dielectric layer. The dielectric film includes a crystalline structure having a substantially uniform composition of zirconium, nitrogen and oxygen. The dielectric film is formed through in situ nitrogen plasma doping of a zirconium layer. The dielectric film functions as a gate dielectric. The dielectric film has a high dielectric constant between about 28-29 and has a low leakage current density of about 4.79×10?5 A/cm2. The substantially uniform distribution of nitrogen throughout the zirconium oxide of the dielectric film increases the k value of the dielectric film by between about 15% to about 17% as compared to a dielectric film that has a non-uniform distribution of nitrogen through a zirconium oxide layer.
