The objective of the LADIR program is the development of low cost arrays for the detection of infrared radiation. It is oriented towards the use of silicon in order to utilize the major unique advantage that is made possible by combining detector arrays along with complementary on-chip silicon electronics. This report details the technical considerations and processing steps required for the development of high quality Ga-doped silicon crystals for use in high performance silicon detectors with maximum responsitivity in the 8-14 micrometer spectral region. Specific processing steps include methods to control the quality of purchased material, purification of the starting material, single crystal perfection, control of compensation and well defined control of the gallium dopant in the final product.
