摘要:
A point of use slurry dispensing system with controls for dilution, temperature and oxidizer/etchant/additive infusion. A slurry in unmixed form and a diluting agent are independently pumped to a pad on a CMP tool. Liquid heaters are used to heat the slurry and the diluting agent to a desirable temperature. The actual mixing occurs at the point of use on the pad or in a dispensing line just prior to the point of use. In some instances a third independent distribution line is used to dispense an oxidizer, etchant and/or chemical additive at or near the point of use.
摘要:
A method of using additives with silica-based slurries to enhance metal selectivity in polishing metallic materials utilizing a chemical-mechanical polishing (CMP) process. Additives are used with silica-based slurries to passivate a dielectric surface, such as a silicon dioxide (SiO.sub.2) surface, of a semiconductor wafer so that dielectric removal rate is reduced when CMP is applied. The additive is comprised of at least a polar component and an apolar component. The additive interacts with the surface silanol group of the SiO.sub.2 surface to inhibit particles of the silica-based slurry from interacting with hydroxyl molecules of the surface silanol group. By applying a surface passivation layer on the SiO.sub.2 surface, erosion of the SiO.sub.2 surface is reduced. However, the metallic surface is not influenced significantly by the additive, so that the selectivity of metal removal over oxide removal is enhanced.

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.

摘要:
This disclosure describes a low particle concentration formulation for slurry which is particularly useful in continuous CMP polishing of copper layers during semiconductor wafer manufacture. The slurry is characterized by particle concentrations generally less than 2 wt %, and advantageously less than 1 wt %. In particular embodiments, where the particle concentration is in a range of 50 to 450 PPM, an 8-fold increase in polishing rate over reactive liquid slurries has been realized. Slurries thus formulated also achieve a reduction in defectivity and in the variations in planarity from wafer to wafer during manufacture, by improving the stability of polishing quality. The slurry formulations permit substantial cost savings over traditional 2-component, reactive liquid and fixed/bonded abrasive slurries. In addition the formulations provides an advantageous way during CMP to easily change the selectivity or rate of removal of one film material vs. another. Yet another use is to provide slurry “pulsing” as a means to activate bonded abrasive or fixed abrasive slurry technology.

The presented idea is a cheap solution for audience monitoring in multicast capable networks e.g. Ethernet, IP or UMTS. There is no need for user equipment in order to monitor the viewers' watching behavior. The measurement is done in the operator's network; therefore, there is no need to contact the end user. The idea can be applied in systems comprising multicast capable network contention server, network devices and user equipment. The content is carried in data packets to the end user. The network devices are remote manageable. The user can choose between several contents. The aim is to measure the user statistics regarding the chosen content. According to the invention it is enough to place a measurement host with our proposed software block in the network, which collects data from the network devices in the edge of the network periodically in order to make a content access survey.

In one embodiment of the invention, conductive support structures (112) are formed within an interlevel dielectric layer. The conductive support structures (112) lie within the bond pad region (111) of the integrated circuit and provide support to portions of the interlevel dielectric layer that have a low Young's modulus. The conductive support structures (112) are formed using the same processes that are used to form metal interconnects in the device region (109) of the integrated circuit, but they are not electrically coupled to semiconductor devices that lie within the device region (109). Conductive support structures (114) are also formed within the scribe line region (104) to provide support to the interlevel dielectric layer in this region of the integrated circuit.
