The present invention relates to a polyamic acid composition for packaging electronic components and a method for packaging electronic components using the same, wherein the polyamic acid composition comprises a dianhydride main component having a benzophenone structure as a dianhydride-based monomer in a high proportion and a diamine component having a benzene ring as a diamine-based monomer, whereby it is possible to improve a coefficient of thermal expansion, a glass transition temperature, an elongation, and the like of a polyimide thin film formed therefrom, and when the polyimide thin film is used as a packaging material for an inorganic material such as a silicon water, it exhibits excellent adhesion to the inorganic material and can be easily removed upon O 2 plasma removal, as well as has a remarkably low residual ratio of organic residues on the surface of the inorganic material after the removal, so that it can be easily used as a packaging material for electronic components and the like. |
