    Abstract: PURPOSE: A semiconductor device and a manufacturing method thereof are provided to improve applicability of a high speed operation element by forming an inter layer dielectric and a gate insulating layer by using different material. CONSTITUTION: A gate electrode(12) is formed on a substrate(10). The gate electrode comprises a projected gate finger. A gate insulating layer(13) is formed on the gate electrode. An inter-layer insulating film(11) is formed on the side of the gate insulating layer and the gate electrode. The inter-layer insulating film comprises a material having dielectric permittivity lower than the gate insulating layer. A graphene layer(14) is formed on the gate insulating layer and the inter-layer insulating film. A source(15a) and a drain(15b) are formed on the graphene layer. Graphene is formed in the lower side of the graphene layer between the source and drain.

    Abstract: Disclosed is a graphene switching device having a tunable barrier. The disclosed graphene switching device includes a first electrode and an insulating layer which are respectively arranged in a first region and a second region which are separated from each other on a conductive semiconductor substrate, a graphene layer which is extended from the insulating layer to the first electrode on the substrate and is separated from the first electrode, a second electrode which faces the insulating layer on the graphene layer, a gate electrode above the graphene layer, and a first well which has a region of the substrate which touches the lower part of the graphene layer which is doped with impurity. The first wall has an energy barrier which is between the graphene layer and the first electrode.
