Never mind answering my question on incentives, a quick and easy search found this:
The Leaf-Chronicle
"The total public investment in the Hemlock plant was $343.1 million, which includes $244.7 million in state incentives, $77.8 million in tax breaks from Montgomery County and $20.6 million in other incentives from the county, according to an Aug. 19, 2011, story by the Nashville Business Journal. That total doesn’t include an additional $60.5 million committed by the Tennessee Valley Authority in the form of infrastructure grants and other incentives."
So, a little over
$400 MILLION in incentives was given the semiconductor company.
