Semiconductor device and bypass capacitor module

A semiconductor device including a substrate having a first surface and a second surface opposite to the first surface;

• a semiconductor element formed on the first surface of the substrate;
• first and second electrodes which are formed directly on the first surface of the substrate, which are electrically connected to the semiconductor element, and which are separated from each other;
• an insulating layer formed on the first surface of the substrate;
• a power supply layer comprising:
• a first power supply layer section directly and electrically connected to the first electrode and extended on the insulating layer;
• and
• a second power supply layer section directly and electrically connected to the second electrode and electrically isolated from the first power supply layer section by electrode isolating regions which separate the first power supply layer section from the second electrode;
• a high dielectric constant layer formed on the first power supply layer section and filling the electrode isolating regions;
• and
• a ground layer which is connected to the second power supply layer section and which is coated on the entirety of the high dielectric constant layer;
• wherein:
• the power supply layer, the high dielectric constant layer, and the ground layer form a bypass capacitor.
