  • Manufacturing resistors with tightened resistivity distribution in semiconductor integrated circuits
    Patent number: 8679936
    Abstract: An anneal recipe is provided to tighten the distribution of resistance values in the manufacture of semiconductor integrated circuits. An adjusted amount of dopant is implanted to compensate for a shift in the distribution of resistance values associated with the anneal recipe. The distribution tightening can be effectuated by including an ammonia gas flow in the anneal recipe.
