    • Roughly described, a transistor is formed with a semiconductor 2D material layer wrapped conformally on at least part of a 3D structure. The 3D structure can be for example a ridge made of a dielectric material, or made of dielectric material alternating longitudinally with a semiconductive or conductive material. Alternatively the 3D structure can be tree-shaped. Other shapes are possible as well. Aspects also include methods for making such structures, as well as integrated circuit layouts defining such structures and methods for developing such layouts, a machine readable data storage medium storing design entries which include some which define such structures and layouts, methods for developing such design entries. Aspects further include corrugated wafers which are prepared as an intermediate product for use in fabricating integrated circuits having a semiconductor 2D material layer disposed conformally on a 3D structure.

    • A method of forming an inverted T shaped channel structure having a vertical channel portion (314) and a horizontal channel portion (322) for an Inverted T channel Field Effect Transistor ITFET device comprises providing a semiconductor substrate (302), providing a first layer (304) of a first semiconductor material over the semiconductor substrate (302), and providing a second layer (306) of a second semiconductor material over the first layer. The first and the second semiconductor materials are selected such that the first semiconductor material has a rate of removal which is less than a rate of removal of the second semiconductor material. The method further comprises removing a portion of the first layer (304) and a portion of the second layer (306) selectively according to the different rates of removal so as to provide a lateral layer (312) and the vertical channel portion (314) of the inverted T shaped channel structure and removing a portion of the lateral layer (312) so as to provide the horizontal channel portion (322) of the inverted T shaped channel structure.

    • Provided is a fin field effect transistor (FinFET) having low leakage current and a method of manufacturing the same. The FinFET includes: a bulk silicon substrate! a fence-shaped body formed by patterning the substrate; an insulating layer formed on a surface of the substrate to a first height of the fence-shaped body! a gate insulating layer formed at side walls and an upper surface of the fence-shaped body at which the insulating layer is not formed; a gate electrode formed on the gate insulating layer; source/drain formed at regions of the fence-shaped body where the gate electrode is not formed. The gate electrode includes first and second gate electrodes which are in contact with each other and have different work functions. Particularly, the second gate electrode having a low work function is disposed to be close to the drain. As a result, the FinFET according to the present invention increases a threshold voltage by using a material having the high work function for the gate electrode and lowers the work function of the gate electrode overlapping with the drain, so that gate induced drain leakage (GIDL) can be reduced.
