Abstract: PURPOSE: A method for manufacturing a FED is provided to apply the effective electric field due to a gate electrode by causing a gate to be closed to an emitter while reducing leakage current through matching an end of an emitter tip to a gate electrode and increasing the height to width ratio of a tip. CONSTITUTION: First, a first insulating layer(42) and a gate electrode(43) are sequentially formed on a selected region of a Si-substrate(41), and then a gate insulating layer(45) having an inclined groove being filled with material for forming an emitter tip is formed. Then, the level of the groove is controlled by depositing a second insulating layer(46) so that the bottom of the groove can be matched to the gate electrode. Next, an emitter tip(48) is formed on the second insulating layer, a total structure is capsized, and the emitter tip is bonded to a glass substrate(49). Then, the emitter tip is exposed by sequentially removing the Si-substrate and the first insulating layer and then etching portions of the gate insulating layer and second insulating layer.

Abstract: PURPOSE: A resonant tunneling transistor having carbon nano tubes as source/drain is provided to allow a switching operation at room temperature. CONSTITUTION: A resonant tunneling transistor includes the first carbon nano tube(1) acting as a source, the second carbon nano tube(2) acting as a drain, a C60 molecule(4) forming an electron overlap region, and an insulative metal compound(3) connecting the first and the second carbon nano tubes(1,2) to the C60 molecule(4), respectively, and acting as a tunneling barrier to electron. The first carbon nano tube(1) is shorter in length than the second carbon nano tube(2), and thereby a switching operation can be possible. In addition, the carbon nano tubes(1,2) have no need of doping, and further, have a nanometer size in all directions as well as an electron flow direction. Moreover, since one-directional tunneling is made in a molecule level, a switching operation at room temperature can be possible.
