NOVELTY - Electronic components (1), preferably semiconductor components comprise a functional layer (2) that comprises metal oxides and is coated with a protective layer (3) comprising an epoxide compound (I) and/or a rearrangement product (II).    USE - The electronic components, preferably semiconductor components are useful for passivating a metal oxide layer functional layer (all claimed). The electronic components are photovoltaic-cell/modules, control electronics of modern flat screens, resistors, potentiometer, sensors, microelectromechanical systems, capacitors, coils, tubes, speaker, relay, inductances, transformers, accumulators, fuel cells, diodes, photodiodes, LED, organic LEDs, solar cells, photocells, photo transistors, optical couplers, thermal generators, transistors, integrated circuits, and surface mounted device.    ADVANTAGE - The electronic components exhibit high electrical conductivity.    DETAILED DESCRIPTION - Electronic components (1), preferably semiconductor components comprise a functional layer (2) that comprises metal oxides and is coated with a protective layer (3) comprising an epoxide compound of formula (I) and/or a rearrangement product of formula (II).    R1-R4 = X or CnX2n+1;    X = H, F, Cl, Br or I, where X contains at least 20%, preferably at least 50%, 55%, 60%, 65% , 70%, 75%, 80%, 85%, 90%, 95% or 100% of F (preferred), Cl, Br or I;    n = 1-10, provided that not all X are simultaneously H, and when R1 and R3 are each H then R2 is C(O)R5 to form a ketone group of formula (R4-C(=O)-CH2-C(=O)-R5) (III); and either    R4a, R5 = cyclic, acyclic, linear or branched, aliphatic or aryl (optionally substituted); or    R4a+R5 = aliphatic or aryl, optionally substituted mono- or polycyclic ring system.    An INDEPENDENT CLAIM is included for producing the electronic components.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a transistor.
