| titleOfInvention | Polyimide precursor and polyimide precursor solution |
| abstract | The present invention provides a polyimide precursor and a resin composition thereof suitably used as a material constituting a semiconductor device or the like, particularly for a portion requiring dimensional stability, adhesion, and heat resistance. The following general formula (wherein R 1 is a tetravalent aromatic ring or aromatic heterocyclic group having 6 to 30 carbon atoms, X is a hydrogen atom or a monovalent organic group having 1 to 30 carbon atoms) And R 2 represents a divalent aromatic ring group having a benzoxazole structure) and at least a repeating unit in which R 1 represents a divalent organic group having a siloxane structure in the following general formula A polyimide precursor having a specific value for the molar ratio between them and the reduced viscosity. [Selection figure] None |
