Popis: We have developed a novel temperature measurement system for controlling the temperature of each layer of multilayered substrates, such as a silicon on insulator (SOI), and have evaluated the system using a three-layered substrate, whose top and bottom layers are silicon, each 360 µm in thickness, and whose interlayer is quartz, 1 mm in thickness. From these results, we have confirmed that the system has a resolution of less than 1°C in the top and bottom layers of the substrate.
