Abstract:
1. A method of manufacturing a capacitor device, comprising the steps of: forming an insulating layer formed of a resin film on a substrate including a wiring layer; forming a first recess portion exposing at least one part of the wiring layer and a second recess portion wherein the insulating layer is left covering the wiring layer by pushing the insulating layer with a die having projected portions using an imprinting process; obtaining lower electrodes respectively by filling a metal layer in the first recess portion and the second recess portion; forming a first capacitor in which a dielectric layer pattern and an upper electrode are formed on the lower electrode in the first recess portion, and a second capacitor in which a dielectric layer pattern and an upper electrode are formed on the lower electrode in the second recess portion, the lower electrode of the second capacitor having an extending portion that extends outside from the dielectric layer pattern and the upper electrode; forming an upper insulating layer on the first capacitor and the second capacitor; forming via holes reaching the upper electrode of the first capacitor, and reaching the upper electrode and the extending portion of the lower electrode of second capacitor by processing the upper insulation layer; forming upper wiring patterns connected to the upper electrode of the first capacitor and connected to the upper electrode and the extending portion of the lower electrode of the second capacitor on the upper insulating layer.
