Solid capacitor and manufacturing method thereof

A manufacturing method for a solid capacitor comprising the steps of:

• forming at least one dense dielectric layer;
• forming at least one loose dielectric layer on each of two opposing sides of the at least one dense dielectric layer, each loose dielectric layer having interstices formed therein in communication with a plurality of openings formed in an outer surface thereof;
• and
• forming an electrode on the outer surface of each loose dielectric layer;
• the electrode having portions thereof disposed in the plurality of openings of a corresponding loose dielectric layer for increasing a contact surface area between the electrode and the corresponding loose dielectric layer.

A manufacturing method for a solid capacitor, comprising the steps of:

• providing at least one dielectric green tape;
• sintering the dielectric green tape to form a dense dielectric layer;
• coating a mixture containing a dielectric material on two opposing sides of the dense dielectric layer;
• sintering the dense dielectric layer coated with the dielectric material mixture, the sintering thereof causing the dielectric material mixture to form a loose dielectric layer on each of the opposing sides of the dense dielectric layer having interstices in communication with a plurality of openings formed in an outer surface of the loose dielectric layer;
• and
• forming an electrode on the outer surface of each loose dielectric layer, the electrode having portions thereof disposed in the plurality of openings of a corresponding loose dielectric layer.

A manufacturing method for a solid capacitor, comprising the steps of:

• forming at least one dielectric green tape;
• mixing a dielectric material with a high temperature volatile material,
• respectively coating opposing sides of the at least one first dielectric layer with a second dielectric layer formed by the mixture of the dielectric material with the high temperature volatile material;
• sintering the coated dielectric green tape to make the first dielectric layer form a dense dielectric layer and to volatilize the high temperature volatile material to make the second dielectric layer become loose dielectric layer having openings formed in an outer surface thereof;
• and
• forming an electrode on the outer surface of each loose dielectric layer, the electrode having portions thereof disposed in the plurality of openings of a corresponding loose dielectric layer.

A manufacturing method for a solid capacitor, comprising the steps of:
