    摘要: A semiconductor device provided with a thin film capacitor having a small equivalent series inductance is provided, which can be operated at a high frequency range and contributes to size reduction of the electronic devices. The semiconductor device comprises a device formed on a silicon substrate 1a, interlayer insulating films 3a, 3b, and 3c, wiring blocks including a power source wire block and a ground wire block, and a thin film capacitor 14 formed on an uppermost insulating layer. The thin film capacitor 14 comprises a lower electrode 6 connected to the ground wire block 4e through a contact 5d, an upper electrode 8 which is connected to the power source wire block 4d through a contact 5d, and which extends above the lower electrode 6, and a dielectric layer 7 which is inserted between the lower and the upper electrodes.
