Query: Metal silicide/poly-Si Schottky diodes for uncooled microbolometers   Nickel silicide Schottky diodes formed on polycrystalline Si<P> films are
proposed as temperature sensors of monolithic uncooled microbolometer IR focal
plane arrays. Structure and composition of nickel silicide/polycrystalline
silicon films synthesized in a low-temperature process are examined by means of
transmission electron microscopy. The Ni silicide is identified as multi-phase
compound composed by 20 to 40% of Ni3Si, 30 to 60% of Ni2Si and 10 to 30% of
NiSi with probable minor content of NiSi2 at the silicide/poly-Si interface.
Rectification ratios of the Schottky diodes vary from ~100 to ~20 for the
temperature increasing from 22 to 70C; they exceed 1000 at 80K. A barrier of
~0.95 eV is found to control the photovoltage spectra at room temperature. A
set of barriers is observed in photo-emf spectra at 80K and attributed to the
Ni-silicide/poly-Si interface. Absolute values of temperature coefficients of
voltage and current are found to vary from 0.3 to 0.6%/K for forward biasing
and around 2.5%/K for reverse biasing of the diodes.
