- (1)
- The temperature measuring results of IFPI were precise and consistent during the fabrication process, with a deviation of less than 0.001%, and the calibrated temperature sensitivity was almost the same as the theoretical value obtained from Equation (2).
- (2)
- The IFPI was able to measure the small-scale strain in the glass package during the curing process. The specific value of 1675 με was close to the numerical results of 1950 με obtained via finite element analysis (deviation less than 13%).
- (3)
- The hermeticity of the glass sealant package was demonstrated to be feasible at high temperatures (20~250 °C) and high pressure (1~10 MPa).
