Ellipsometry, XRR, and GCIB-TOF-SIMS are applied to investigation of the spin-coating process as comparison of spin-coated samples and vacuum evaporated samples. The residual solvent of spin-coating process was observed in spin-coated samples by GCIB-TOF-SIMS. The result suggested that it can cause the decrease of refractive index observed in ellipsometry.
