Abstract: This invention provides an electronic circuit component authenticity determination method capable of determining whether an electronic circuit component is a component manufactured by an authorized manufacturer. The electronic circuit component is operated under a predetermined condition at the time of manufacturing or initialization of the electronic circuit component. The waveform of power consumption or an electromagnetic wave at the time of the operation is measured and stored as first waveform data. An authenticity determination target electronic circuit component is operated under the predetermined condition. The waveform of power consumption or an electromagnetic wave is measured and temporarily stored as second waveform data. The stored first waveform data is compared with the second waveform data. It is determined that the electronic circuit component is a genuine when the waveform data match.

Abstract: High precision MEMESs can be manufactured in a large amount without requiring a vacuum process or a lithography process. A film is aligned with a die so as to contact with each other. The film has a functional layer and a releasing layer printed thereon. The die is configured to mold a structure which comprises a functional layer retention part retaining the functional layer and a frame supporting the functional layer retention part. The resin filled between the die and the film is cured. Then, the film is separated from the die so that the functional layer is released from the releasing layer and transferred on the resin cured in the die, thereby the structure is formed.
