An electronic device has a wiring board mounted with an electronic circuit chip. A recess or through-hole is formed in a major surface of the wiring board on which the electronic circuit chip is mounted at a position corresponding to a central portion of the electronic circuit chip. Air trapped in a space between the electronic circuit chip and the wiring board is collected in the recess or through-hole to form a void separated from the electronic circuit chip.

Noise generated at high frequencies at the time of simultaneous switchings of logical circuits is reduced by lowering an inductance from LSI to a capacitor formed on a substrate. The capacitor is formed to ensure that an inductance from a bonding pad for the LSI loaded on the substrate to an electrode of the capacitor is 0.05 nanohenry. The lower inductance from the LSI to the capacitor allows a reduction in the amount of the noise at high frequencies among those generated in power supply system, whereby the rising time of signals is made shorter, and the speed of arithmetic operation can be increased.

An input-output wiring for the power circuit and a ground layer are formed on a metal substrate of a power hybrid integrated circuit apparatus. A plurality of windows are opened at predetermined positions of a circuit substrate to which electronic parts such as an IC driver, a chip resistor etc. are connected. Ceramic chips are soldered on the exposed surface of the metal substrate in the windows, and the power semiconductor elements are connected through metal bridges on the ceramic chips. Connection between lower electrode of adjoining power semiconductor elements or between lower part of the power semiconductor element and an input/output wiring is made by means of a part of the metal bridge.
