| Outline of Final Research Achievements |
In order to evaluate the optical constants, accurate reflectance evaluation is required. Significant things are higher order light removal, polarization control, scattering component removal. Among them, a high order light control mechanism and a polarization control mechanism were developed, and a beam line capable of accurate optical constant evaluation was constructed. In particular, the absorption coefficient of photoresist has become an important parameter of resist development, and the measured values by transmission method and reflection method are compared. In addition, the optical constants of Si, Mo, Zr, Si3N4, and TaN which are often used in the EUV region were measured. Furthermore, in the resonance absorption region of the carbon K absorption end of the photoresist, the optical constant was measured by the reflection method and compared with the spectrum measured by the total electron yield method.
