    • The present invention provides a multilayer circuit board for mounting thereon a semiconductor chip or other electronic elements having electrode terminals or other connection terminals which are arranged in a grid, staggered, or close-packed manner in an improved form to enable reduction in the number of the wiring layers for lead wiring lines, thereby facilitating the production of multilayer circuit boards and providing an improved product reliability. The multilayer circuit board comprises: a base board having a mounting surface for mounting thereon a semiconductor chip and/or other electronic elements having lattice-arranged connection terminals; connection terminal pads arranged on the mounting surface to form a plane lattice corresponding to the lattice arrangement of the connection terminals and having lattice sites each occupied by one of the connection terminal pads; lead wiring lines lying on the mounting surface and having one end connected to the connection terminal pads and the other end extending outwardly from the plane lattice; and the said plane lattice having a peripheral zone including periodic vacant lattice areas formed by vacant lattice sites occupied by no connection terminal pads.

    • An inductor includes a core substrate including minute column-like electrical conductors extending between a front surface and a back surface of the core substrate. Each column-like electrical conductor is insulated from adjacent column-like electrical conductors by being surrounded by an insulating material. Insulation layers are formed on the front surface and the back surface of the core substrate, respectively. At least two connection electrical conductors extend through each of the insulation layers. Each connection electrical conductor is electrically connected to a plurality of the column-like electrical conductors. Wirings are formed on each of the insulation layers to connect said connection electrical conductors to each other electrically. The wirings, the connection electrical conductors and the column-like electrical conductors are connected to form a coil in a three-dimensional manner.
    • 电感器包括芯基板,其包括在芯基板的前表面和后表面之间延伸的微小列状电导体。 每个柱状电导体被绝缘材料包围,与相邻的柱状电导体绝缘。 绝缘层分别形成在芯基板的前表面和后表面上。 至少两个连接电导体延伸穿过每个绝缘层。 每个连接电导体电连接到多个柱状电导体。 在每个绝缘层上形成布线,以将所述连接电导体彼此电连接。 连线,连接电导体和列状电导体被连接以形成三维方式的线圈。
