Title: Non-volatile memory electronic device having nanowire channel and nanoparticle floating gate node and method thereof
Inventor: KIM SANGSIG
IPC: H01L51/05
Filed: 2008-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a nanowire-nanoparticle memory electron device that not only allows the device to be operable even if the nonoparticle is used for a charge storage layer and a gate operating voltage is low but also reduces the thickness of a tunneling layer and that of an insulating layer, and improved in the direct contact degree of the device.  <P>SOLUTION: This invention relates to a non-volatile memory electronic device and a method of manufacturing the same. As illustrated in Fig. 3, a nanowire 41 on the surface of which the tunneling layer 42 is evaporated allows the nanoparticle to be adsorbed by the tunneling layer evaporated on the surface of the nanowire. A semiconductor nanoparticle includes a semiconductor nanowire 41 used as a charge transfer channel, and a semiconductor nanoparticle for use in a charge storage layer 43. This structure results in allowing a charge transferred through the nanowire to be tunneled to the nanoparticle by the voltage applied to a gate. Thus, the charge is tunneled from the nanoparticle to the nanowire by the change of the voltage to be reapplied.  <P>COPYRIGHT: (C)2008,JPO&INPIT
