A plurality of parallel groove portions and a region sandwiched between the groove portions are formed in a substrate, and a conductive resin is supplied to the groove portions and the region and is fixed, whereby the groove portions are filled with the conductive resin and the region is covered with the conductive resin. The supplied conductive resin is not expanded outward, and the electrode with a designed width can be formed.

摘要： An object is to provide a single crystal semiconductor layer with extremely favorable characteristics without performing CMP treatment or heat treatment at high temperature. Further, an object is to provide a semiconductor substrate (or an SOI substrate) having the above single crystal semiconductor layer. A first single crystal semiconductor layer is formed by a vapor-phase epitaxial growth method on a surface of a second single crystal semiconductor layer over a substrate; the first single crystal semiconductor layer and a base substrate are bonded to each other with an insulating layer interposed therebetween; and the first single crystal semiconductor layer and the second single crystal semiconductor layer are separated from each other at an interface therebetween so as to provide the first single crystal semiconductor layer over the base substrate with the insulating layer interposed therebetween. Thus, an SOI substrate can be manufactured.

摘要： A resistance calculation activator determines whether or not an electric car is stopped on the basis of a drive command signal and an external signal, and activates a resistance calculator if a powering command is input as the drive command when it is determined that the electric car is stopped. The activated resistance calculator computes, within a resistance calculation period, a resistance value of an AC motor that produces driving force for the electric car, on the basis of a d-axis voltage command value and a d-axis current value supplied to the AC motor.
