  • Patent number: 10168229
    Abstract: Embodiments disclosed herein generally relate to a temperature sensor disposed in an apparatus. In many semiconductor, liquid crystal display, solar panel or organic light emitting display fabrication processes, RF power is utilized to either ignite a plasma within the processing chamber or to provide supplemental energy to the process. Temperature control during many processes may be beneficial in order to produce a consistent product. Temperature sensors or thermocouples are sometimes utilized to measure the temperature of a substrate within a processing chamber. The RF power may have a negative impact on the temperature sensor. By coating the temperature sensor with a nanoparticle based metal coating, such as a silver coating, the negative impacts of the RF power on the temperature sensor may be reduced without contaminating the process, and an accurate temperature measurement may be obtained.
    Type: Grant
