Embodiments of the invention include an electrical package and methods of forming the package. In one embodiment, a transformer may be formed in the electrical package. The transformer may include a first conductive loop that is formed over a first dielectric layer. A thin dielectric spacer material may be used to separate the first conductive loop from a second conductive loop that is formed in the package. Additional embodiments of the invention include forming a capacitor formed in the electrical package. For example, the capacitor may include a first capacitor plate that is formed over a first dielectric layer. A thin dielectric spacer material may be used to separate the first capacitor plate form a second capacitor plate that is formed in the package. The thin dielectric spacer material in the transformer and capacitor allow for increased coupling factors and capacitance density in electrical components.
