摘要： A method for making a semiconductor device is described. That method comprises forming a dielectric layer on a substrate, and forming a first metal layer on a first part of the dielectric layer, leaving a second part of the dielectric layer exposed. After a second metal layer is formed on both the first metal layer and the second part of the dielectric layer, a masking layer is formed on the second metal layer.

摘要： A nanotube transistor, such as a carbon nanotube transistor, may be formed with a top gate electrode and a spaced source and drain. Conduction along the transistor from source to drain is controlled by the gate electrode. Underlying the gate electrode are at least two nanotubes. In some embodiments, the substrate may act as a back gate.

摘要： In a metal gate replacement process, a stack of at least two polysilicon layers or other materials may be formed. Sidewall spacers may be formed on the stack. The stack may then be planarized. Next, the upper layer of the stack may be selectively removed. Then, the exposed portions of the sidewall spacers may be selectively removed. Finally, the lower portion of the stack may be removed to form a T-shaped trench which may be filled with the metal replacement.

摘要： A wafer may be rotated while etching to displace bubbles that may form, for example, from a reaction between silicon and water. As a result, a hydrophobic layer, which would otherwise be created by the bubbles, cannot form, resulting in a more uniform etch rate in some embodiments.

摘要： A semiconductor device comprising a semiconductor body having a top surface and a first and second laterally opposite sidewalls as formed on an insulating substrate is claimed. A gate dielectric is formed on the top surface of the semiconductor body and on the first and second laterally opposite sidewalls of the semiconductor body. A gate electrode is then formed on the gate dielectric on the top surface of the semiconductor body and adjacent to the gate dielectric on the first and second laterally opposite sidewalls of the semiconductor body. The gate electrode comprises a metal film formed directly adjacent to the gate dielectric layer. A pair of source and drain regions are then formed in the semiconductor body on opposite sides of the gate electrode.
