Abstract:
An embodiment of the present invention relates to a diffusing agent composition used in printing an impurity-diffusing component onto a semiconductor substrate, wherein the diffusing agent composition contains: a hydrolysis product of alkoxysilane (A); a component (B) containing at least one selected from the group consisting of a hydrolysis product of alkoxy titanium, a hydrolysis product of alkoxy zirconium, titania fine particle, and zirconia fine particle; an impurity-diffusing component (C); and an organic solvent (D).
