Abstract:
A laminated capacitor and a method for manufacturing the same are provided. The method includes operations of providing a substrate; forming a first isolation insulation spacer and a plurality of discrete bottom bonding pads on the substrate; forming a sub-capacitor structure on the bottom bonding pads, which comprises a plurality of discrete bottom electrodes, a plurality of discrete top electrodes, and a dielectric medium located between the bottom electrodes and the top electrodes, wherein the plurality of bottom bonding pads are respectively electrically connected with the plurality of bottom electrodes in one-to-one correspondence; and repeatedly performing an operation of forming a connection structure and the sub-capacitor structure for N times on the sub-capacitor structure, such that N connection structures and N+1 sub-capacitor structures are alternately arranged along a direction perpendicular to the substrate, wherein N is an integer greater than or equal to 1.
