Paper Abstract
InSb focal plane array (FPA) detectors are key components in IR imaging systems that significantly impact both cost and
performance. Detector performance is affected by the electronic and crystallographic quality and uniformity of the
semiconductor substrate. High-volume, high-yield production of InSb wafers to the standards required for FPA device
manufacture requires growth of on-axis {111} crystals. An inherent source of variation hindering on-axis Czochralski
crystal growth is anisotropic dopant incorporation. We report on newly developed growth methods that eliminate the
negative effects of anisotropic dopant incorporation enabling high volume manufacturing of {111}-oriented substrates
and discuss the consequential manufacturing benefits. We also report on a characterization technique to characterize
microscale dopant variation across the wafer.
