    摘要: In a method of manufacturing a semiconductor device, a semiconductor substrate of a first conductivity type having first and second surfaces is prepared. Second conductivity type impurities for forming a collector layer are implanted to the second surface using a mask that has an opening at a portion where the collector layer will be formed. An oxide layer is formed by enhanced-oxidizing the collector layer. First conductivity type impurities for forming a first conductivity type layer are implanted to the second surface using the oxide layer as a mask. A support base is attached to the second surface and a thickness of the semiconductor substrate is reduced from the first surface. An element part including a base region, an emitter region, a plurality of trenches, a gate insulating layer, a gate electrode, and a first electrode is formed on the first surface of the semiconductor substrate.

    摘要: PER when a wireless apparatus is connected with a predetermined wireless access point is estimated on the basis of three parameters of the received signal strength, the interference signal strength, and the interference adjacency, which have been transmitted from the wireless access point, then the communication throughput is calculated by using the estimated PER, and the connection with a wireless access point expected to have highest communication efficiency is performed. As a result, it is possible to select a wireless access point having high communication efficiency with good precision, as compared with a method, in the related art, of simply performing a connection with a wireless access point having high received signal strength or a method of simply performing a connection with a wireless access point where an interference wave is strong.
