Eco-friendly Synthesis of Photosensitive Poly(Amic Acid) Salt as Patternable Polyimide Precursor |
| 초록 |
Polyamic acid salt (PAAS) paired with photo cross-linkable organic bases is one class of photosensitive polyimides (PSPIs), which dissolve in the water and can be cross-linked under UV light. The PAAS is converted to polyimide (PI) at relatively a low temperature and simplifies the patterning process, which allows us to utilize them as the insulation and packaging material in the semiconductor. The preparation route for PAAS is a multi-step reaction including the synthesis of poly(amic acid) (PAA) in an organic solvent followed by the salt-forming process using tertiary amines, which causes an increase in cost and environmental pollution. In here, we suggest the one-step and green synthesis of PAAS using water as the solvent. We also demonstrate the preparation of patterned polyimide with tens of micrometer through the lithographic process followed by the thermal treatment. |
