A semiconductor package applicable to integrated circuits and other semiconductor devices of the kind needing high integration and high speed operation. The package has a printed circuit board implemented by a glass cloth impregnated with epoxy, bismaleimide-triazine (BT) or similar resin, a power source layer provided in the circuit board in a plate structure, a ground layer formed on the surface of the circuit board in a plate structure, and a thin film laminate wiring formed on the ground layer in a plate structure and consisting of copper and benzocyclobutene. The package desirably shields leakage currents and matches a characteristic impedance with accuracy, thereby noticeably reducing noise and enhancing high speed signal transmission. |
