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.
Abstract: A compound is represented by Formula (1): wherein, each X is independently oxygen, sulfur, or selenium; m is 0 or 1; each n is independently 0 or 1; R1-R3 are each independently, for example, hydrogen or alkyl having 1 to 20 carbons; wherein (i) in the case of m=0, it is excluded that all of R1-R3 are hydrogen at the same time; (ii) in the case of m=0, n=0 and in the case that m is 0, one of n is 0 and the other is 1, it is excluded that “both of X are sulfur and all R3s are the same atoms or groups at the same time”; (iii) in the case of m=0, n=1, it is excluded that all R3s are the same atoms or groups at the same time, and at least one of R3s is hydrogen.
