Abstract

A passive electrical component includes an inorganic dielectric coating layer laser applied to a conductor layer.

Claims (29)

1. A component comprising:

a substrate;

a first conductor layer in contact with said substrate;

a second conductor layer in contact with said substrate; and

an inorganic coating layer laser applied to said substrate to provide a passive electrical component between the first and second conductor layers, wherein said inorganic coating layer includes a dielectric particle and a conductive particle.

2. The component as recited in claim 1 , wherein said inorganic coating layer has a thickness between approximately 0.6 microns to 10 microns.

3. The component as recited in claim 1 , wherein said inorganic dielectric coating layer is selected from: halfnium oxide, silicone dioxide, silicon nitrides, fused aluminum oxide, Al 0.66 Hf 0.33 O 3 , Al 0.8 Hf 0.2 O 3 , and Al 0.5 Y 0.5 O 3 .

4. The component as recited in claim 1 , wherein said inorganic coating layer is between said conductor layer and a high permeability layer.

5. A capacitor comprising:

a substrate;

a plurality of conductor layers, at least one conductor layer in contact with said substrate; and

an inorganic coating layer between each two of said plurality of conductor layers, each of said inorganic coating layer having a thickness between approximately 0.6 microns to 10 microns to provide a capacitor upon said substrate, wherein said inorganic coating layer includes a dielectric particle and a conductive particle.

6. The capacitor as recited in claim 5 , wherein said inorganic coating layer is selected from: halfnium oxide, silicone dioxide, silicon nitrides, fused aluminum oxide, Al 0.66 Hf 0.33 O 3 , Al 0.8 Hf 0.2 O 3 , and Al 0.5 Y 0.5 O 3 .

7. The capacitor as recited in claim 5 , wherein said substrate is conductive.

8. The capacitor as recited in claim 5 , wherein said substrate is non-conductive with a conductive layer deposited thereon.

9. The capacitor as recited in claim 5 , wherein a portion of a module forms said substrate.

10. The capacitor as recited in claim 9 , wherein said module is manufactured of aluminum.

11. An inductor comprising:

a substrate;

a plurality of conductor layers;

a plurality of high permeability layers, at least one of said plurality of high permeability layers adjacent to said substrate; and

an inorganic coating layer between each of said plurality of conductor layers and each of said plurality of high permeability layers to provide an inductor upon said substrate, wherein said inorganic coating layer includes a dielectric particle and a conductive particle.

12. The inductor as recited in claim 11 , wherein said inorganic coating layer is selected from: halfnium oxide, silicone dioxide, silicon nitrides, fused aluminum oxide, Al 0.66 Hf 0.33 O 3 , Al 0.8 Hf 0.2 O 3 , and Al 0.5 Y 0.5 O 3 .

13. The inductor as recited in claim 11 , wherein said substrate is conductive.

14. The inductor as recited in claim 11 , wherein said substrate is a non-conductive substrate with a conductive layer deposited thereon.

15. The inductor as recited in claim 11 , wherein a portion of a module forms said substrate.

16. The component as recited in claim 1 , wherein said substrate is a conductive substrate.

17. The component as recited in claim 1 , wherein said substrate is a non-conductive substrate.

18. The component as recited in claim 1 , wherein said conductor layer is selected from: aluminum, nickel, copper or gold.
