摘要： Some embodiments include semiconductor processing methods in which a copper barrier is formed to be laterally offset from a copper component, and in which nickel is formed to extend across both the barrier and the component. The barrier may extend around an entire lateral periphery of the component, and may be spaced from the component by an intervening ring of electrically insulative material. The copper component may be a bond pad or an interconnect between two levels of metal layers. Some embodiments include semiconductor constructions in which nickel extends across a copper component, a copper barrier is laterally offset from the copper component, and an insulative material is between the copper barrier and the copper component.

摘要： A method of forming a sharp silicon structure, such as a silicon field emitter, includes oxidizing the silicon structure to form an oxide layer thereon, then removing the oxide layer. Oxidizing may occur at a low temperature and form a relatively thin (e.g., about 20 Å to about 40 Å) oxide layer on the silicon field emitter. The oxide layer may be removed by etching. A silicon field emitter that has been fabricated in accordance with the method is substantially free of crystalline defects and may include an emitter tip having a diameter as small as about 40 Å to about 20 Å or less.

摘要： A method for making an electrode structure and an electrode structure for a display device comprising a gate electrode proximate to an emitter and a focusing electrode separated from the gate electrode by an insulating layer containing a ridge. When the focusing electrode is an aperture-type electrode, the upper surface of the ridge protrudes closer to the emitter than the sidewall of the gate electrode or the sidewall of the focusing electrode. When the focusing electrode is a concentric-type electrode, the ridge protrudes above the upper surface of the gate electrode or the upper surface of the focusing electrode.

摘要： A method of sharpening a tapered or pointed silicon structure, such as a silicon field emitter. The method includes oxidizing the silicon field emitter to form an oxide layer thereon and removing the oxide layer. Oxidizing occurs at a low temperature and forms a relatively thin (e.g., about 20 .ANG. to about 40 .ANG.) oxide layer on the silicon field emitter. The oxide layer may be removed by etching. The method may be employed to sharpen existing silicon structures or in fabricating tapered or pointed silicon structures. A silicon field emitter that has been sharpened or fabricated in accordance with the method is substantially free of crystalline defects and includes an emitter tip having a diameter as small as about 40 .ANG. to about 20 .ANG. or less.
