Abstract: A semiconductor device and process for making the same are disclosed which use reticulated conductors and a width-selective planarizing interlevel dielectric (ILD) deposition process to improve planarity of an interconnect layer. Reticulated conductor 52 is used in place of a solid conductor where the required solid conductor width would be greater than a process and design dependent critcal width (conductors smaller than the critical width may be planarized by an appropriate ILD deposition). The reticulated conductor is preferably formed of integrally-formed conductive segments with widths less than the critical width, such that an ILD 32 formed by a process such as a high density plasma oxide deposition (formed by decomposition of silane in an oxygen-argon atmosphere with a back-sputtering bias) or spin-coating planarizes the larger, reticulated conductor as it would a solid conductor of less than critical width. Using such a technique, subsequent ILD planarization steps by, e.g.

Abstract: An apparatus integrating pad conditioning device (44) with a wafer carrier device (24) for chemical-mechanical polishing applications includes an attaching mechanism (45) for associating conditioning device (44) with wafer carrier device (24). Conditioning surface (84) of conditioning device (44) conditions the polishing pad associates with attaching mechanism (45). Carrier device (24) receives and holds wafer (42) so that wafer (42) and conditioning surface (44) contact the polishing pad (42) to simultaneously condition polishing pad (26) and polish wafer (42).

Abstract: A pad conditioning method and apparatus for chemical-mechanical polishing. A polishing pad (114) is attached to a platen (112) and used to polish a wafer (116). Rotating arm (118) positions the wafer (116) over the pad (114) and applies pressure. During wafer polishing particles build up on the polishing pad (114) reducing its effectiveness. Either during or in between wafer polishing (or both), conditioning head (122) is applied to pad (114) to remove the particles from pad (114) into the slurry (120). Conditioning head (122) comprises a semiconductor substrate (126) that is patterned and etched to form a plurality of geometries (128) having a feature size on the order of polishing pad (114) cell size.
