Abstract: A process for forming an initial section or like component featuring a hollow interior to a final shape by high internal pressure in the sealed hollow interior using a medium that can flow. In order to shape-form the initial section featuring at least one corner region—preferably at least two corner regions—the wall sections adjacent to the corner region are preshaped in a curved manner—as viewed in cross-section—counter to the direction of applied pressure, and subsequently re-shaped by applying the high internal pressure of the medium that can flow, displacing the corner region in the direction in which the pressure is applied. To that end a section with hollow space delimited by section walls is employed in which two section walls define each corner region of the section cross-section, whereby at least one of the section walls at the corner region features a region that is curved in cross-section.

Abstract: Copper can be pattern etched at acceptable rates and with selectivity over adjacent materials using an etch process which utilizes a solely physical process which we have termed “enhanced physical bombardment”. Enhanced physical bombardment requires an increase in ion density and/or an increase in ion energy of ionized species which strike the substrate surface. To assist in the removal of excited copper atoms from the surface being etched, the power to the ion generation source and/or the substrate offset bias source may be pulsed. In addition, when the bombarding ions are supplied from a remote source, the supply of these ions may be pulsed. Further, thermal phoresis may be used by maintaining a substrate temperature which is higher than the temperature of a surface in the etch chamber.
