Abstract:
In the manufacture of integrated circuits, reactive compositions that include a reactive etchant species and an oxygen-containing species can provide selective removal of target material and can reduce contamination of gas delivery lines.
Abstract:
Plasma processing systems and methods for using pre-dissociated and/or pre-ionized tuning gases are disclosed herein. In one embodiment, a plasma processing system includes a reaction chamber, a support element in the reaction chamber, and one or more cathode discharge assemblies in the reaction chamber. The reaction chamber is configured to produce a plasma in an interior volume of the chamber. The support element positions a microelectronic workpiece in the reaction chamber, and the cathode discharge assembly supplies an at least partially dissociated and/or ionized tuning gas to the workpiece in the chamber.

Abstract:
A method of forming a substrate opening includes forming a plurality of side-by-side openings in a substrate. At least some of immediately adjacent side-by-side openings are formed in the substrate to different depths relative one another. Walls that are laterally between the side-by-side openings are removed to form a larger opening having a non-vertical sidewall surface where the walls were removed in at least one straight-line vertical cross-section that passes through the sidewall surface orthogonally to the removed walls.
Abstract:
A capacitively coupled plasma reactor comprising a processing chamber, a first electrode, a second electrode and a thermoelectric unit. The processing chamber has an upper portion with a gas inlet and a lower portion, and the upper portion is in fluid communication with the lower portion. The first electrode has a front side and a backside and is positioned at the upper portion of the processing chamber. The second electrode is positioned in the lower portion of the processing chamber and is spaced apart from the front side of the first electrode. The thermoelectric unit is positioned proximate to the backside of the first electrode and is capable of heating and cooling the first electrode.
Abstract:
A capacitor forming method includes forming an electrically conductive support material over a substrate, forming an opening through at least the support material to the substrate, and, after forming the opening, forming a capacitor structure contacting the substrate and the support material in the opening. The support material contains at least 25 at % carbon. Another capacitor forming method includes forming a support material over a substrate, forming an opening through at least the support material to the substrate, and, after forming the opening, forming a capacitor structure contacting the substrate and the support material in the opening. The support material contains at least 20 at % carbon. The support material has a thickness and the opening has an aspect ratio 20:1 or greater within the thickness of the support material.

Abstract:
Some embodiments include methods in which a pair of spaced-apart adjacent features is formed over a substrate. The features have silicon dioxide surfaces. Silicon nitride is deposited between the features. A first region of the silicon nitride is protected with a mask while a second region is not. The second region is removed to form an opening between the features. Some embodiments include semiconductor constructions that contain a pair of spaced-apart adjacent features. The features are lines extending along a first direction and are spaced from one another by a trench. Alternating plugs and intervening materials are within the trench, with the plugs and intervening materials alternating along the first direction. The intervening materials consist of silicon nitride, and the plugs have lateral peripheries that directly contact silicon dioxide of the features, and that directly contact silicon nitride of the intervening regions.
