Silicon wafers and the like are cleaned using new scrubber-type apparatus in which measures are taken to compensate for differential cleaning of the central region of the wafer by: using rotary brushes having one or more non-contact portions arranged in the section thereof that faces the central region of the substrate, or toggling the relative position of the wafer and the rotary brushes, or directing cleaning fluid(s) preferentially towards the central region of the wafer. Another aspect of the invention provides scrubber-type cleaning apparatus in which the rotary brushes are replaced by rollers (110). A web of cleaning material (116) is interposed between each roller and the substrate. Various different webs of cleaning material may be used, e.g. a length of tissue, a continuous loop of cleaning material whose surface is reconditioned on each cleaning pass, adhesive material provided on a carrier tape, etc.

摘要:
A passivating coupling material for, on the one hand, passivating a dielectric layer in a semiconductor device, and on the other hand, for permitting or at least promoting liquid phase metal deposition thereon in a subsequent process step. In a particular example, the dielectric layer may be a porous material having a desirably decreased dielectric constant k, and the passivating coupling material provides steric shielding groups that substantially block the adsorption and uptake of ambient moisture into the porous dielectric layer. The passivating coupling materials also provides metal nucleation sides for promoting the deposition of a metal thereon in liquid phase, in comparison with metal deposition without the presence of the passivating coupling material. The use of a liquid phase metal deposition process facilitates the subsequent manufacture of the semiconductor device. In one example, the passivating coupling material has multiple Si atoms in its chemical composition, which desirably increases the thermal stability of the material.

A system for processing a semiconductor substrate during fabrication of semiconductor devices provides a plurality of semiconductor substrate processing stations in a physically integrated system, as well as a semiconductor substrate transport system for transporting a semiconductor substrate between the respective processing stations. In particular, the processing system according to the present invention favors the use of liquid phase process steps, particularly deposition process steps, instead of gas or vapor phase processing. Even more particularly, the system contemplates deposition of a metallic barrier layer 30 on the semiconductor substrate in liquid phase.
