Abstract:
A diffusion agent composition including an impurity-diffusing component (A); a binder resin (B) that thermally decomposes and disappears below a temperature at which the impurity-diffusing component (A) begins to thermally diffuse; SiO2 fine particles (C); and an organic solvent (D) that contains an organic solvent (D1) having a boiling point of at least 100° C.
