Abstract (en)

[origin: WO02073660A2] A system and method of minimizing stress related to the ramp rate of variable by limiting the ramp rate as a function of the current value of the variable is provided. More specifically, the present invention provides a system and method of maintaining the radial delta temperature of a semiconductor substrate or other heated body below the crystal slip curve by dynamically controlling the temperature ramp rate during processing.
