摘要： Low-thermal-expansivity polyimides have a linear rigid skeleton, so that adhesion between perfectly cured low-thermal-expansivity polyimide films is very low. On the other hand, a film of a polyimide having a flexible skeleton shows high adhesiveness even after perfect curing, so that it is possible to enhance adhesion between the low-thermal-expansivity polyimide films by interposing a polyimide having a flexible skeleton. A flexible polyimide thin film is formed as a highly adhesive film on a low-thermal-expansivity polyimide film in a half-cured state, then metallic wiring is applied thereon, followed by formation of another highly adhesive thin film in a half-cured state, and then a low-thermal-expansivity polyimide film is further formed thereon. It is possible to provide a multilayer wiring structure which has improved adhesion between the low-thermal-expansivity polyimide film and the wiring pattern layer or the substrate.

摘要： A process of forming a patterned polyimide film includes the step of conversion of a polyimide precursor into polyimide. The improvement is imidizing the precursor by means of a chemical imidizing reagent. Typically a film of polyimide precursor is formed on a substrate, and mask which is negative with respect to the desired pattern is formed on the film. The film is contacted through the mask with a chemical imidizing reagent to effect imidization of unmasked portions, thereby forming polyimide. The mask and masked portions of the film are removed, leaving the desired polyimide pattern. High temperatures and harmful etchants can be avoided.

摘要： The present invention provides a process for producing a metal-polyimide composite material such as a wiring board. In production thereof, deterioration of polyamide film due to oxidation during imidization of a polyimide precursor in contact with metal such as copper or silver can be prevented. The present invention is characterized by using a polyimide precursor having an acidic functional group which is masked. Examples of the polyamide precursor are polyamic acid epoxy adducts, amido polyamic acids, silylated polyamic acids, etc.
