Abstract
Described are processes for developing laminated circuit boards, as well as the resulting circuit boards themselves. Accordingly, at least two circuit boards at least partially overlap each other, and at least one through-hole is formed in an overlapping region thereof. The through-hole is filled with an electrically-conductive material, forming a through-via that enables the circuit boards to be electrically connected. When a circuit on each circuit board is laid out so that a part thereof reaches a region in which the through-via is to be formed, then that part of the circuit can be electrically connected to the through-via. Thus, portions of the circuits on the circuit boards can be electrically connected to each other via common through-vias to realize an integrated device in which the circuits on the laminated circuit boards function.
