CVD REACTOR AND METHOD FOR CONTROLLING THE SURFACE TEMPERATURE OF THE SUBSTRATES
In a CVD reactor and a method for the open-loop/closed-loop control of the surface temperature of substrates arranged therein, the substrates lie on substrate-retaining elements, which are each supported by a gas cushion. Actual values of the surface temperatures associated with a respective substrate-retaining element are successively measured and the surface temperatures are controlled in a closed-loop manner to a common value by varying the gas cushion height. After measuring each actual value of the surface temperature associated with a substrate-retaining element and using only the respective last-measured actual value of the surface temperatures of each substrate-retaining element, a first average value is calculated, a difference value associated with the substrate-retaining element is calculated, and an approximate actual value is calculated for each of the other substrate-retaining elements by adding the associated difference value to the first average value, said approximate actual value being used for the open-loop/closed-loop control.

The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a support unit horizontally maintaining a substrate; a laser irradiation unit for irradiating the substrate with a laser; a photo-detector for detecting an energy of a reflective light reflected from the substrate among a laser irradiated on the substrate; and a processor, and wherein the processor irradiates a first laser of a first output to the substrate, and sets a second output of a second laser for irradiating the substrate to heat the substrate, based on an energy of a first reflective light reflected from the substrate by the first laser detected from the photo-detector.
Plasma processing apparatus, temperature control method, and temperature control program
A heater controller controls power supplied to a heater capable of adjusting the temperature of a placement surface such that the heater reaches a set temperature. A temperature monitor measures the power supplied in the non-ignited state where the plasma is not ignited and in the transient state where the power supplied to the heater decreases after the plasma is ignited, while the power is controlled such that the temperature of the heater becomes constant. A parameter calculator calculates a heat input amount and the thermal resistance by using the power supplied in the non-ignited state and in the transient state to perform a fitting on a calculation model for calculating the power supplied in the transient state. A set temperature calculator calculates the set temperature of the heater at which the wafer reaches the target temperature, using the heat input amount and thermal resistance.
