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: A method for removing particulate contaminants from a semiconductor wafer is disclosed. A wafer 10 is held in a wafer holder 12 at cleaning station 14. Cleaning station 14 has a rinse fluid supply system 18 which supplies, e.g. deionized water, to the wafer surface during particle removal. A cleaning pad 20 is mounted on a platen 22, substantially in the plane of wafer 10. Platen 22 is coupled to a drive mechanism 24, which may for example be an electric motor, and drive mechanism 24 is coupled to station 14 by an engagement mechanism 26 which provides vertical displacement to engage pad 20 and wafer 10 for particle removal, and also provides a controlled pad contact pressure during particle removal. In operation, rinse fluid from 18 is supplied to slowly rotating wafer 10, while pad 20 is rotated, preferably at 200 to 600 rpm, and contacted with wafer 10.
