Abstract: In a method for manufacturing a device fabrication wafer, an SiC epitaxial wafer that is an SiC wafer 40 having a monocrystalline SiC epitaxial layer formed thereon is subjected to a basal plane dislocation density reduction step of reducing the density of basal plane dislocations existing in the epitaxial layer of the SiC epitaxial wafer, to thereby manufacture the device fabrication wafer for use to fabricate a semiconductor device. In the basal plane dislocation density reduction step, the SiC epitaxial wafer is heated under Si vapor pressure for a predetermined time necessary to reduce the density of basal plane dislocations, without formation of a cap layer on the SiC epitaxial wafer, so that the density of basal plane dislocations is reduced with suppression of surface roughening.

Abstract: [Problem] To provide a disposable diaper more effective in odor eliminating. [Means for Solving Problem] The above problem is solved by a disposable diaper, comprising a liquid pervious face sheet 30, a liquid impervious sheet 11, an absorbent body 56 interposed therebetween, an outer sheet 12 covering a back surface of the liquid impervious sheet 11, an after-treatment tape on an external surface of a back body part B and an odor eliminating printed sheet 25 interposed between the liquid impervious sheet 11 and the outer sheet 12 in the body part B having the after-treatment tape and formed by printing with ink a sheet base material.
