Z. Farukhi et al., Temperature uniformity optimization for a silicon implant anneal into GaAsusing Opus (TM) simulation software, J ELEC MAT, 28(12), 1999, pp. 1370-1375
OPUS(TM), which stands for "Optimized Uniformity Simulator", has been descr
ibed in the Literature as a powerful tool to assist in the optimization of
temperature uniformity in the STEAG Electronic Systems series of rapid ther
mal processors. Historically, this tool has been used extensively for a var
iety of silicon processing. With this simulation, the temperature uniformit
y of 100 mm Si3N4 encapsulated GaAs with a dual silicon implant anneal at 8
47 degrees C, 40 s was optimized to <2 degrees C across the wafer. Ramp rat
es less than or equal to 20 degrees C/s were obtained without slip.
