Abstract
Procédé de fabrication d'un produit intermédiaire du type polyamide à fonctions acides à partir de composés du type diamine et/ou diaminoamide et d'un dianhydride d'acide tétracarboxylique en tant que composés monomères. Il est utilisé un solvant inerte épuré et les composés monomères utilisés sont préalablement épurés par recristallisation et présentent des teneurs réduites en impuretés et en acide libre. L'invention est applicable, dans réalisation de semi-conducteurs, notamment pour munir ceux-ci d'une pellicule de protection superficielle ou d'une pellicule isolante intermédiaire.
