    Abstract: In conjunction with sputtering a metal, especially copper, into high aspect-ratio holes in a wafer, an oblique ion milling method in which argon ions or other particles having energies in the range of 200 to 1500e V are directed to the wafer at between 10 and 35° to the wafer surface to sputter etch material sputter deposited preferentially on the upper corners of the holes. The milling may be performed in the sputter deposition chamber either simultaneously with the deposition or after it or performed afterwards in a separate milling reactor. A plurality of ion sources arranged around the chamber improve angular uniformity or arranged axially improve radial uniformity or vary the angle of incidence. An annular ion source about the chamber axis allows a plasma current loop. Anode layer ion sources and sources composed of copper are advantageous.

    Abstract: A high-reliability damascene interconnect structure and a method for forming the same are provided. An interlevel dielectric (42) is formed over a semiconductor topography (40), and trenches (44, 46) for interconnects and/or vias are formed in the interlevel dielectric (42). A trench liner (48) may then be deposited, followed by deposition of a low-resistance metal (50) such as copper. The low-resistance metal deposition is preferably stopped before the trenches (44, 46) are entirely filled. Portions of the metal and trench liner external to the trenches (44, 46) are subsequently removed, such that low-resistance metal interconnect portions (52, 54) are formed. A high-melting-point metal (60), such as tungsten, is deposited over upper surfaces of the interconnect portions (52, 54) and interlevel dielectric (42). Portions of the high-melting-point metal are removed to form interconnects having a low-resistance metal lower portion (52, 54) and a high-melting-point metall upper portion (62, 64).

    Abstract: In described examples, a microelectronic device (100) is formed by providing a substrate having a recess (124) at a top surface (130), and a liner layer (132) formed over the top surface (130) of the substrate, extending into the recess (124). A protective layer (138) is formed over the liner layer (132), extending into the recess (124). A CMP process (142) removes the protective layer (138) and the liner layer (132) from over the top surface (130) of the subsrate, leaving the protective layer (138) and the liner layer (132) in the recess (124). The protective layer (138) is subsequently removed from the recess (124), leaving the liner layer (132) in the recess (124). The substrate may include an interconnect region (104) with a bond pad (116) and a PO layer (122) having an opening which forms the recess (124); the bond pad (116) is exposed in the recess (124). The liner layer (132) in the recess (124) may be a metal liner suitable for a subsequently-formed wire bond or bump bond.
