The semiconductor device and its production method for the biosensor device which is based on molecular electronics and molecular electronics

摘要

This invention as a foundation for the biosensor which is based on molecular electronics or molecular electronics regards the semiconductor surface which is structured. It is the hetero structure which is formed from the layer where the semi-conducting material to which the coming out spot, has separated this from two semi-conducting material layers which have not been doped, differs quite is thin (number nm). This material layered product is made to cleave vertically vis-a-vis layer plane surface, and layer of center is etched selectively. The source and the drain contact for conductive organic wire, evaporating, it produces the thin metal membrane. As the electrostatic gate, it is possible to utilize the conductive layer of center. Can assemble in order to make the wire of 1 - several books contact, to do with the separation and the evaporation of 2 times which are consecutively done. As for the organic wire which is thought, for example, it is molecule, DNA- origonukureochido, or the carbon nano- tube which possess conjugate electronic system. The unique organism molecule those interactions (for example DNA- protein interaction) are detected furthermore by functionating with reseputa for recognizing the organism molecule (antibody and protein), as the high sensitivity biosensor in order you analyze, and to measure and it becomes possible to utilize.
