PASSIVATION FILM, SEMICONDUCTOR DEVICE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

There has been found a halogen-containing aromatic compound which can form a film having an excellent water and oxygen blocking property after polymerization. The present invention provides a semiconductor device and an organic EL element, each having a high-performance passivation film, i.e., a passivation film including a fluorine-containing polymer having a repeating unit defined by the formula (1): -(X₂C-Ar-CX₂)- wherein X is hydrogen or fluorine; Ar is a divalent aromatic ring optionally substituted with fluorine; and when Ar has no fluorine, one or more of X's are fluorine.
