摘要:
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.

A component-embedded board fabrication method includes detecting, before the board is covered with a first insulating layer, the actual position of a first electronic component formed on a surface of the board, calculating a displacement between the design position of the first electronic component on the surface of the board and holding the displacement as first displacement data, and correcting, based on the first displacement data, design data to be used for processing the board after the board is covered with the first insulating layer.

A semiconductor device drive circuit is provided for turning on and off a semiconductor device that comprises a main static induction transistor and a sense static induction transistor. The drive circuit comprisees a first current source having one terminal connected to a power supply and its other terminal connected to said main static induction transistor, a second current source having one terminal connected to the power supply and its other terminal connected to said sense static induction transistor, a third current source having terminal connected to the power supply and its other terminal connected to the first current source, and a fourth current source having one terminal connected to the power supply and its other terminal connected to the second current source. The drive circuit also has comparing and control means for turning the first and second current sources on to apply a bias when the semiconductor device is to be turned on and for turning off the first and second current sources and turning on the third and fourth current sources when a voltage obtained by sensing a current flowing through the sense static induction transistor is higher than a specific voltage.
