Electronic structures and molecular orientations of thin films of silicon phthalocyanine dichloride have been observed by X-ray absorption fine structure microscopy using soft X-rays from synchrotron light source. It was found that the molecular orientations of deposited layers at room temperature are different depending on the substrates. We have also observed the surface diffusion of the molecules upon heating at nanometer scale, and clarified that the molecular orientation at room temperature changes at high temperature.
