Definitions
- Silicon wafer substrate locking stage silicon wafer substrate temperature measurement method
- the present invention is a stage for holding a silicon wafer substrate equipped with a lamp heater for heating at the lower part of the stage, and has a silicon wafer substrate temperature measurement function without contact with the silicon wafer substrate. Regarding the stage.
- the stage of the present invention continuously measures the temperature of at least one point on the silicon wafer substrate without contacting the silicon wafer substrate in a state where one silicon wafer substrate is locked. .
- thermocouple As a technique for measuring the temperature of a silicon wafer substrate, there are a contact measurement method using a thermocouple and a non-contact measurement method using a radiation thermometer.
- Patent Document 1 discloses a method for arranging a thermocouple on a stage! Speak.
- Patent Document 1 in order to provide a temperature-programmed desorption analyzer with a sample surface temperature and a thermocouple controlled temperature, etc., at least the upper part of the sample stage is made of a highly thermally conductive material, There is a method in which the temperature difference from the sample stage is eliminated by bringing the couple and sample surface into contact with the sample stage and heating them by heat conduction. As an example of this method, there is a description of an example in which the upper and lower parts of the sample stage are made of quartz and heated using an infrared lamp.
- thermocouple is provided at the tips of a plurality of silicon wafer pins provided so as to be movable up and down through the stage.
- thermocouple senses infrared rays, so that the thermocouple for temperature monitoring is higher than the sample by the transmitted infrared rays. There were problems such as becoming.
- thermocouple In the method described in Patent Document 2, it is necessary for the thermocouple to always contact the silicon wafer in order to measure the temperature of the silicon wafer substrate. For this reason, the difference in thermal expansion between the thermocouple and the silicon during temperature rise / fall is also required. There were problems such as rubbing at the contact area of the wafer, generation of contamination, and generation of particles that caused a decrease in yield.
- the lamp heater has a feature that heat is given to the processed object by causing the light emitted from the light source to reach the processed object. Due to the feature of applying heat with light, the heat generated varies depending on the way light is received. For example, even if a semiconductor wafer and an aluminum plate receive the same amount of light, they generate different amounts of heat and have different temperatures. That is, when the lamp heating light is emitted to the processed semiconductor wafer placed in the aluminum chamber, the temperature of the semiconductor wafer and the temperature of the aluminum chamber are different. Therefore, measuring the temperature of the aluminum chamber does not mean that the temperature of the semiconductor wafer has been measured.
- the temperature measurement target is a semiconductor wafer, which has a very high infrared transparency and is a processed material, so the infrared thermometer cannot measure the temperature. Became clear.
- thermocouple is indispensable, but in this case as well, due to the first problem described above, measurement is performed with a thermocouple attached to the chamber.
- the temperature does not indicate the temperature of the semiconductor wafer.
- measuring the temperature by attaching a thermocouple directly to the treated object requires work to attach or remove the thermocouple every time it is processed, and it is unrealistic and unsuitable for the site where processing speed is required. is there.
- the thermocouple is destroyed at an extremely early stage by being exposed to an erosive gas environment in the chamber. There is also the problem that when the thermocouple reacts with the gas, particles are generated, which adheres to the treated material and causes contamination.
- the surface emissivity of the semiconductor wafer may change during the process, and the surface emissivity of the semiconductor wafer may change as the force changes. Doing so creates an error. In extreme cases, the change in emissivity can vary greatly from about 0.2 to about 0.8. For this reason, the error may be as much as 10% at the 1000 ° C level.
