Photosensitive polyimide and negative type photoresist composition containing the same |
| abstract |
A photosensitive polyimide and negative type photo-resist composition containing the same are provided. The photosensitive polyimide is represented by formula (I): n n n n n n n n n n wherein X 1 and X 3 are the same or different organic functional groups having four covalent bonds; X 2 and X 4 are the same or different organic functional groups having two covalent bonds, and X 2 contains functional groups of OH or COOH and any one selected from the functional groups below: n n n n n n n n n n wherein R is H or CH 3 , p and q are integers of 1 to 20, and m and n in formula (I) are numbers of repeat units. |
