DIFFUSING AGENT COMPOSITION, AND METHOD FOR FORMING AN IMPURITY DIFFUSION LAYER

摘要

A diffusing agent composition contains a condensation product (A) and an impurity diffusion component (B). The condensation product (A) is a reaction product yielded by hydrolyzing an alkoxysilane. The impurity diffusion component (B) is a monoester or diester of phosphoric acid, or a mixture thereof.
