Abstract:
The present invention relates to a new class of dielectric polymer material, which is particularly suitable for the manufacturing of electronic devices. The dielectric polymer material is formed by reacting bismaleimide compounds and shows an advantageous well-balanced profile of favorable material properties. The bismaleimide compounds have an oligomeric structure with an amide-imide extended repeating unit in the middle part of the molecule and maleimide groups at each terminal end of the molecule. There is further provided a method for forming said dielectric polymer material. Beyond that, the present invention relates to the dielectric polymer material and to an electronic device comprising the same.

Abstract:
An electronic device and methods for its preparation comprising an active area between first and second conductive layers on a substrate; the active area is in a well whose bottom is a patterned first conductive layer on the substrate, the sides of the well are bank structures comprising a non- radiative active fluoropolymer which overlap the edges of the first conductive layer and which are in contact with the substrate. The well contains active materials, preferably introduced by a solution method such as ink-jet. The second conductive layer is located over the top of the well.
