| 摘要 |
An apparatus for measuring a temperature of a substrate is disclosed. The apparatus includes a phosphor material in direct contact with the substrate and in thermal contact with the substrate, the phosphor material producing a fluorescent response in a first wavelength range when exposed to a electromagnetic radiation in a second wavelength range, the fluorescent response decaying at a decay rate that is related to a temperature of the phosphor material, and the phosphor material producing a first set of non volatile byproducts when expose to a plasma.
