Electrical component with a dielectric passivation stack

An electrical component comprising:

• a substrate defining a base of the electrical component;
• a conductor stack having multiple stacked layers defining at least a portion of an electrically conductive path and mounted to the substrate, the multiple stacked layers including an upper layer, an inner layer, and an adhesion layer;
• a dielectric passivation stack encasing at least a portion of the conductor stack and defining at least one opening for connection to the electrically conductive path;
• and
• an electrically conductive cap configured to close the opening and further defining the electrically conductive path.
