Abstract
A capacitor (1) includes a main body (10) in which a dielectric layer (13) and an electrode layer (11) are laminated, and an external electrode (20) connected to at least a part of the main body. The electrode layer (11) includes a heavy edge portion (16) with a connecting part (18), which connects to the external electrode and is thicker than an internal electrode part (15). The capacitor (1) further includes an edge support layer (12) that is made of metal and is laminated on the heavy edge portion (16).
Claims24
A capacitor comprising a main body, in which a dielectric layer and an electrode layer are laminated, and an external electrode connected to at least a part of the main body,
- wherein the electrode layer includes an internal electrode part and a heavy edge portion, the heavy edge portion being a connecting part, which connects to the external electrode and is thicker than the internal electrode part, and
- the capacitor further comprises an edge support layer that includes at least one layer that is made of metal and laminated on at least one of a top and a bottom of the heavy edge portion.
A method of manufacturing a capacitor including a main body in which dielectric layers and electrode layers are laminated, wherein at least part of the main body is connected to external electrodes,
- the method comprising forming an electrode layer on a dielectric layer, wherein the forming the electrode layer includes forming an internal part and heavy edge portions, the heavy edge portions being connecting parts that connect to the external electrodes respectively and are thicker than the internal electrode part, and
- the method further comprises forming an edge support layer that includes at least one layer on the heavy edge portions.
A system for manufacturing a capacitor including a main body, in which dielectric layers and electrode layers are alternately laminated, wherein at least part of the main body is connected to an external electrode, the system comprising:
- a chamber that provides a reduced pressure environment:
- a transferring device that transfers workpiece for the main body during manufacturing inside the chamber:
- a dielectric layer forming device that forms a dielectric layer on the workpiece:
- an electrode layer forming device that forms an electrode layer on the dielectric layer together with heavy edge portions with connecting parts that connect to the external electrode and are thicker than an internal electrode part, the dielectric layer forming device and the electrode layer forming device being disposed along the transferring device inside the chamber:
- and
- at least one edge support layer forming device that is disposed along the transferring device inside the chamber and forms an edge support layer over the heavy edge portions.
