摘要： A schottky barrier transistor and a method of manufacturing the same are provided. The method includes forming a gate insulating layer and a gate on a substrate, forming a spacer on a sidewall of the gate, and growing a polycrystalline silicon layer and a monocrystalline silicon layer on the gate and the substrate, respectively, using a selective silicon growth. A metal is deposited on the polycrystalline silicon layer and the monocrystalline silicon layer. Then, the metal reacts with silicon of the polycrystalline silicon layer and the monocyrstalline silicon layer to form a self-aligned metal silicide layer. Therefore, selective wet etching for removing an unreacted metal after silicidation can be omitted. Furthermore, etching damage caused during the formation of the spacer can be decreased during the growth of the monocrystalline silicon layer, thereby improving the electrical characteristics of devices.

摘要： Provided are a Schottky barrier tunnel transistor and a method of manufacturing the same that are capable of minimizing leakage current caused by damage to a gate sidewall of the Schottky barrier tunnel transistor using a Schottky tunnel barrier naturally formed at a semiconductor-metal junction as a tunnel barrier. The method includes the steps of: forming a semiconductor channel layer on an insulating substrate; forming a dummy gate on the semiconductor channel layer; forming a source and a drain at both sides of the dummy gate on the insulating substrate; removing the dummy gate; forming an insulating layer on a sidewall from which the dummy gate is removed; and forming an actual gate in a space from which the dummy gate is removed. In manufacturing the Schottky barrier tunnel transistor using the dummy gate, it is possible to form a high-k dielectric gate insulating layer and a metal gate, and stable characteristics in silicidation of the metal layer having very strong reactivity can be obtained.

摘要： Provided are a Schottky barrier tunnel single electron transistor and a method of manufacturing the same that use a Schottky barrier formed between metal and semiconductor by replacing a source and a drain with silicide as a reactant of silicon and metal, instead of a conventional method of manufacturing a single electron transistor (SET) that includes source and drain regions by implanting dopants such that an artificial quantum dot is formed in a channel region. As a result, it does not require a conventional PADOX process to form a quantum dot for a single electron transistor (SET), height and width of a tunneling barrier can be artificially adjusted by using silicide materials that have various Schottky junction barriers, and it is possible to improve current driving capability of the single electron transistor (SET).

摘要： A device using an ambipolar transport of an SB-MOSFET and a method for operating the same are provided. The SB-MOSFET includes: a silicon channel region; a source and a drain contacted on both sides of the channel region and formed of material including metal layer; and a gate formed on the channel region, with a gate dielectric layer interposed therebetween. Positive (+), 0 or negative (−) gate voltage is selectively applied to the gate, the channel becomes off-state when the gate voltage between a negative threshold voltage and a positive threshold voltage is applied, and the channel becomes a first on-state and a second on-state when the gate voltage is lower than the negative threshold voltage or higher than the positive threshold voltage. Accordingly, it is possible to implement three current states, that is, hole current, electron current, and no current. The SB-MOSFET can be applied to a multi-bit memory and/or multi-bit logic device.

摘要： The present invention relates to a method of manufacturing a nano transistor. The present invention manufactures the nano transistor without changing a conventional method of forming the nano transistor formed on a SOI substrate. Further, the present invention includes forming a N well and a P well at giving regions of an underlying silicon substrate so that a given voltage can be individually applied to a NMOS transistor and a PMOS transistor. Therefore, the present invention can control the threshold voltage to prevent an increase of the leakage current.

摘要： Provided is a thermoelectric device including two legs having a rough side surface and a smooth side surface facing each other. Phonons may be scattered by the rough side surface, thereby decreasing thermal conductivity of the device. Flowing paths for electrons and phonons may become different form each other, because of a magnetic field induced by an electric current passing through the legs. The smooth side surface may be used for the flowing path of electrons. As a result, in the thermoelectric device, thermal conductivity can be reduced and electric conductivity can be maintained.
