Abstract:
Multilayer structure used as a material having high permittivity comprises a number of layers each of thickness less than 500 Angstroms. Some of the layers are based on aluminum, hafnium and oxygen, notably hafnium dioxide (HfO2) and alumina (Al2O3). Preferably, these layers comprise mixed oxides of formula HfxAlyOz whose stoichiometry varies from one layer to another. Preferred Features: The thickness of each layer is 1-200 Angstrom , preferably 1-100 Angstrom , and most preferably 1-50 Angstrom . The structure comprises at least five layers. At least one of the external layers is alumina (Al2O3). Each layer is deposited by atomic layer deposition (ALD).

PROBLEM TO BE SOLVED: To provide a compact monolithic integrated circuit with superior electrical characteristics, particularly Q-values, of inductive elements with respect to electrical characteristics. SOLUTION: A monolithic integrated circuit 1 with an incorporated inductive element 20 has a semiconductor substrate layer 2, a passivation layer 4 covering the semiconductor substrate layer 2 and metallic contact pads 5 which are connected to the substrate 2 and pierce the passivation layer 4, in order to have the pad surfaces on the same plane as the top surface 6 of the passivation layer 4. The integrated circuit also includes the whirlpool shape winding 20, formed in a plane parallel with a top surface 6 of the passivation layer 4. The winding 20 consists of copper turns 21-23, 27 and 28 with thicknesses of not smaller than 10 μm. The ends of the winding 20 are extended downward from the winding plane, so as to form extended parts 12 connected to the contact pads 5.
