  • Patent number: 7694688
    Abstract: The present invention generally provides an apparatus and method for processing and transferring substrates in a multi-chamber processing system that has the capability of receiving and performing single substrate processing steps performed in parallel, while using the many favorable aspects of batch processing. Embodiments of the invention described herein are adapted to maximize system throughput, reduce system cost, reduce cost per substrate during processing, increase system reliability, improve the device yield on the processed substrates, and reduce system footprint. In one embodiment, the cluster tool is adapted to perform a wet/clean process sequence in which various substrate cleaning processes are performed on a substrate in the cluster tool.

  • Publication number: 20080163900
    Abstract: A method and system for cleaning a batch of substrates is provided. The system includes a first cluster of vertical processing chambers, an IPA reservoir, and an IPA delivery system in fluid communication with the IPA reservoir and the first cluster of vertical processing chambers, wherein the IPA delivery system is adapted to transfer IPA vapor between the IPA reservoir and the first cluster of vertical processing chambers. In certain embodiments, the system further comprises a first main circulation tank, a second main circulation tank, a reservoir-cluster recirculation circuit in fluid communication with the first main circulation tank and the second main circulation tank and with each processing chamber in the first cluster of vertical processing chambers, and a dosing circuit comprising a plurality of additive sources in fluid communication with the first main circulation tank and the second main circulation tank.

  • Publication number: 20080163890
    Abstract: A method and system for cleaning a substrate is provided. More particularly systems and methods that allows for precise tailoring of megasonics distribution at a substrate surface to be above the threshold required for particle removal efficiency (PRE), yet below the value which causes structural damage are provided. This method utilizes multiple megasonics transducers operated at very low power densities in a single substrate immersion processor. This method is shown to produce high cleaning efficiencies without damage to 45 nm devices. Further, sonoluminescence studies demonstrate that the transducers are operated in the single bubble sonoluminescence (SBSL) regime, well below the cavitation threshold for transient multiple-bubble sonoluminescence (MBSL).

  • Patent number: 6878213
    Abstract: Semiconductor substrates, particularly metallized substrates such as partially processed wafers, are rinsed with an aqueous medium, preferably deionized water, which further contains an anti-corrosive chemical agent or agents selected so as to minimize corrosion of metals resulting from contact with the water. The amount of anti-corrosive chemical agent is maintained in a controlled manner at a predetermined level or within a predetermined range preferably the rinsing with aqueous medium containing anticorrosive chemical agent is also carried out for a specified time, followed by further rinsing with deionized water alone. The rinsing may be combined, either in the same vessel or in a different vessel, with a subsequent drying step, such as a drying process utilizing a drying vapor introduced into the rinse tank or into a downstream vessel.
