Semiconductor device and position detecting method using the semiconductor device

摘要

An object of the present invention is to solve a problem of a conventional semiconductor device in that although information such as whether the semiconductor device exists in a predetermined space and information on an ID and the like included in the semiconductor device can be obtained, a position where the semiconductor is located in the predetermined space cannot be identified. The semiconductor device includes a signal sorting portion which sorts a signal based on a signal output from the outside and a signal detecting portion for detecting the signal output from the outside. In a structure of the semiconductor device including the signal sorting portion and the signal detecting portion, a position detecting system is developed base on signals from a plurality of interrogators.
