摘要： A methodology for varying the depth of a design feature on a semiconductor wafer. Vias are formed according to design requirements. Nonfunctioning vias may also be placed at a location with respect to a design feature. After vias are formed, the semiconductor wafer is caused to undergo an ashing process followed by the application of an organic planarizing layer. The design features are then formed. If the depth of the design features does not meet design requirements, another semiconductor wafer may be processed to meet design requirements by varying the ashing conditions, choice of organic planarizing layer and/or the nonfunctioning and/or functioning via placement. Design features having various depths on a single semiconductor wafer may be formed with a single lithographic process.

摘要： Methods of minimizing or eliminating plasma damage to low k and ultra low k organosilicate intermetal dielectric layers are provided. The reduction of the plasma damage is effected by interrupting the etch and strip process flow at a suitable point to add an inventive treatment which protects the intermetal dielectric layer from plasma damage during the plasma strip process. Reduction or elimination of a plasma damaged region in this manner also enables reduction of the line bias between a line pattern in a photoresist and a metal line formed therefrom, and changes in the line width of the line trench due to a wet clean after the reactive ion etch employed for formation of the line trench and a via cavity. The reduced line bias has a beneficial effect on electrical yields of a metal interconnect structure.

摘要： An inductively coupled plasma reactor and method for processing a semiconductor wafer (28). The inductively coupled plasma reactor (10) includes a plasma source (16) having a plurality of channels (38, 44) in which processing gases are independently supplied to each channel. A gas supply system (20) includes a plurality of gas feed lines (34, 35, 36) each capable of supplying an individual flow rate and gas composition to the plurality of channels (38, 44) in the plasma source (16). Each channel is surrounded by an independently powered RF coil (54, 56), such that the plasma density can be varied within each channel (38, 44) of the plasma source (16). In operation, a material layer (66) overlying a semiconductor wafer (28) is either uniformly etched or deposited by localized spatial control of the plasma characteristics at each location (64) across the semiconductor wafer (28).

摘要： A first metallic hard mask layer over an interconnect-level dielectric layer is patterned with a line pattern. At least one dielectric material layer, a second metallic hard mask layer, a first organic planarization layer (OPL), and a first photoresist are applied above the first metallic hard mask layer. A first via pattern is transferred from the first photoresist layer into the second metallic hard mask layer. A second OPL and a second photoresist are applied and patterned with a second via pattern, which is transferred into the second metallic hard mask layer. A first composite pattern of the first and second via patterns is transferred into the at least one dielectric material layer. A second composite pattern that limits the first composite pattern with the areas of the openings in the first metallic hard mask layer is transferred into the interconnect-level dielectric layer.
