Power core devices and methods of making thereof

A method for making a device comprising:

• providing at least one planar capacitor having a patterned side and a non-patterned side;
• providing at least one foil structure comprising at least one formed on foil singulated capacitor having a foil side and a component side;
• and
• laminating said component side of said foil structure to said patterned side of said planar capacitor structure;
• etching said foil side of said foil structure and etching said non-patterned side of said planar capacitor structure forming a power core;
• and
• forming at least one signal layer onto said power core.
