  • Patent number: 7333212
    Abstract: In a method for measuring an absorption coefficient and a reduced scattering coefficient of a multiple scattering medium, a source light beam is outputted, and is transformed into a transformed light beam that includes a mutually parallel circularly polarized photon pair. The transformed light beam is split into a signal beam, which is focused and projected into the multiple scattering medium to produce a diffused polarized photon pair density wave, and a reference beam, which is converted into a reference heterodyne interference signal. The diffused polarized photon pair density wave is converted into a test heterodyne interference signal. Amplitude attenuation and phase delay of the signal beam that has propagated through the multiple scattering medium is obtained based on the reference and test heterodyne interference signals, from which the absorption coefficient and the reduced scattering coefficient of the multiple scattering medium are inferred.

  • Patent number: 7268048
    Abstract: Methods of preparing conductive regions such as source/drain regions for silicidation procedures, has been developed. The methods feature removal of native oxide as well as removal of deposited arsenic based defects from conductive surfaces prior to deposition of a metal component of subsequently formed metal silicide regions. Arsenic ions implanted for N type source/drain regions are also implanted into insulator regions such as insulator filled shallow trench isolation regions. A hydrofluoric acid cycle used as a component of the pre-silicidation preparation procedure can release arsenic from the shallow trench isolation regions in the form of arsenic based defects, which in turn can re-deposit on the surface of source/drain region. Therefore pre-silicidation preparation treatments described in this invention feature removal of both native oxide and arsenic based defects from conductive surfaces prior to metal silicide formation.
