Si wafer temperature measurement

Webb27 nov. 2012 · Laser beam size on the wafer surface was approximately 50 μm in diameter. The incident laser excitation power at the wafer surface was fixed at 20 mW for 650 nm excitation and 50 mW for 827 nm excitation. The penetration depths in Si of the excitation wavelengths of 650 nm and 827 nm are ∼4.0 μm and ∼10 μm, respectively (Fig. 1 ). WebbCI Semi offers NIR pyrometers that can measure as low as 180C.
