The Durimide 100 Series are a range of self priming, non-photosensitive polyamic acid formulations which become fully stable polyimide coatings after thermal curing. They can be photo-imaged using a positive photoresist mask. Softbaked polyimide films are coated with photoresist, softbaked, exposed and post exposure baked. When the photoresist is developed, the polyimide is etched, transferring the pattern from the photoresist into the polyimide. The photoresist is subsequently removed with a solvent rinse and the polyimide thermally cured. The minimum geometry which can be achieved by this method depends upon the thickness of the polyimide at softbake. The smallest resolvable feature is approximately four times the softbake film thickness.
Thickness of softbaked films ranges from 4um to 21um. Thickness range given in the process description above is for cured films.
