A method for forming a copper structure with reduced dishing, using a self-aligned copper electroplating process. The process begins by providing a semiconductor structure having a dielectric layer thereover, wherein the dielectric layer has a trench therein. A barrier layer is formed over the dielectric layer, a seed layer is formed on the barrier layer, and an insulating layer is formed on the seed layer. The insulating layer is patterned so as to expose the seed layer on the bottom and sidewalls of the trench, preferably using the trench photo mask. A copper layer is selectively electroplated onto the exposed seed layer on the bottom and sidewalls of the trench, while the insulating layer prevents copper deposition outside of the trench. The copper layer, the insulating layer, and the seed layer are planarized, stopping at the dielectric layer. Because of the self-aligned copper geometry, the copper suffers reduced dishing.

The sag rate of fusion pipes (e.g., isopipes (<bold>13< / highlight>) used in an overflow downdraw fusion process) is reduced by the application of axial forces (F) to the end regions (<bold>23< / highlight>) of the pipe. The axial forces are applied to the end regions below the pipe's neutral axis (<bold>19< / highlight>) so that a bending moment is generated which opposes gravitational sagging of the middle of the pipe. The use of such sag-controlling axial forces increases pipe service life by, for example, at least a third.
