Semiconductor apparatus integrating an electrical device under an electrode pad
Abstract:
A semiconductor apparatus includes a device, two metal-wiring layers, and an insulation film. The device includes first and second electrodes. The two metal-wiring layers include uppermost and next-uppermost metal-wiring layers. The insulation film is formed on the uppermost metal-wiring layer and includes first and second pad openings. The uppermost metal-wiring layer has a first portion exposed to air through the first pad opening and forming a first electrode pad, and the uppermost metal-wiring layer has a second portion exposed to air through the second pad opening and forming a second electrode pad. The first and second electrode pads are located over the device and are electrically connected to the first and second electrodes, respectively. The next-uppermost metal-wiring layer has a first portion located under the first electrode pad and electrically connected thereto, and a second portion located under the second electrode pad and electrically connected thereto.
