Field: Semiconductors (Electrical engineering)
Classification: CPC G  C  H | IPC C  G  H

Claim 9:
10. A method of manufacturing a semiconductor device, the method comprising:
forming a polymer precursor, the forming of the polymer precursor comprising:
reacting 3,3,4,4-biphenyltetracarboxylic dianhydride with a first reactant to form a second reactant; and
reacting the second reactant with 4,4-(4,4-isopropylidenediphenyl-1,1-diyldioxy)dianiline (BAPP) to form the polymer precursor;

forming a polymer mixture, the polymer mixture comprising the polymer precursor and a solvent;
applying the polymer mixture over a substrate;
exposing and developing at least a portion of the polymer mixture to form a developed dielectric;
curing the developed dielectric to form a dielectric layer; and
forming a conductive feature over the dielectric layer.
