Abstract: An oxide evaporation material according to the present invention includes a sintered body containing indium oxide as a main component thereof and cerium with a Ce/In atomic ratio of 0.001 to 0.110. The L* value in the CIE 1976 color space is 62 to 95. The oxide evaporation material with the L* value of 62 to 95 has an optimal oxygen amount. Accordingly, even when a small amount of an oxygen gas is introduced into a film-formation vacuum chamber, a transparent conducting film having a low resistance and a high transmittance in the visible to near-infrared region is formed by vacuum deposition methods. Since the amount of the oxygen gas introduced is small, the difference in composition between the film and the evaporation material is made small. This reduces the variations in composition and characteristics among films formed in large quantities.

Further, the modified region is formed closer to the side surface of the substrate than the pad. In this manner, defects in cutting shape in a cutting process of a semiconductor wafer using stealth dicing can be reduced or prevented.
