| titleOfInvention | Low Dielectric Polyimide Film and Manufacturing Method Thereof |
| abstract | The present invention relates to a low-k polyimide film having a reduced number of bubbles and a method for manufacturing a polyimide film comprising the same, comprising biphenyltetracarboxylic dianhydride (BPDA) and pyromellitic dianhydride (PMDA) It is obtained by imidizing a polyamic acid solution containing a dianhydride component and a diamine component including oxydianiline (ODA), paraphenylene diamine (PPD) and m-tolidine, and phosphorus-based A polyimide film comprising the compound is provided. |
