摘要： A rapid thermal processing (RTP) system including a transmission pyrometer monitoring the temperature dependent absorption of the silicon wafer for radiation from the RTP lamps at a reduced power level. A look-up table is created relating unnormalized values of photodetector photocurrents with wafer and radiant lamp temperatures. A calibrating step measures the photocurrent with known wafer and lamp temperatures and all photocurrents measured thereafter are accordingly normalized. The transmission pyrometer may be used for closed loop control for thermal treatments below 500° C. or used in the pre-heating phase for a higher temperature process including radiation pyrometry in closed loop control. The pre-heating temperature ramp rate may be controlled by measuring the initial ramp rate and readjusting the lamp power accordingly. Radiation and transmission pyrometers may be included in an integrated structure with a beam splitter dividing radiation from the wafer.

A lip extends radially inwardly from the inner perimeter of the band to support the substrate. The band and lip can be formed from silicon carbide, and the radiation absorption surface can be an oxidized layer of silicon carbide. In one version, the band and lip have a combined thermal mass Tm, and the radiation absorption surface has an absorptivity A and a surface area Sa, such that the ratio (A×Sa)/Tm is from about 4×10−5 m2K/J to about 9×10−4 m2K/J.

摘要： Systems, methods, and other embodiments associated with a DC notch gear filter are described. According to one embodiment, an apparatus includes a digital high pass filter having a cutoff frequency and a gear mechanism configured to successively change the cutoff frequency of the high pass filter based on a sequence of cutoff frequencies. The apparatus also includes a direct current (DC) estimator configured to estimate a DC offset of a digital input signal to the high pass filter based, at least in part, on an output signal of the high pass filter as a cutoff frequency is successively changed. A direct current (DC) compensator is configured to subtract the estimated DC offset from the input signal to the high pass filter.
