| titleOfInvention | A kind of polyimide glue for alkali corrosion resistant chip passivation layer and preparation method |
| abstract | A polyimide glue solution for alkali corrosion-resistant chip passivation layer and a preparation method thereof, the invention relates to a polyimide glue solution and a preparation method. The invention solves the problems that the existing polyimide coating as a passivation layer has poor alkali corrosion resistance and cannot maintain the surface quality and surface flatness of the coating in an alkaline environment. The polyimide glue solution is prepared from polyimide solution, nano-barium sulfate after titanium dioxide coating and interface coupling agent; preparation method: 1. preparation of polyimide solution; 2. mixing. |
