Semiconductor thermal process control utilizing position oriented temperature generated thermal mask
Patent number: 7667162Abstract: During fabrication, a rotating semiconductor substrate is radiated in accordance with a thermal recipe. Temperature measurements of the semiconductor substrate are obtained along with the position of the semiconductor substrate at the time of each temperature measurement.
