    摘要: An apparatus and a method for cleaning a wafer are described. A chamber has a substrate support. A nozzle is disposed above the substrate support to spray de-ionized water droplets. The nozzle is coupled to a source of de-ionized water and a source of nitrogen. The nozzle is configured to mix the de-ionized water and the nitrogen outside the nozzle to have independent flow rate control of the two fluids for an optimized atomization in terms of spray uniformity in droplet size and velocity distributions. The nozzle to wafer distance can be adjusted and tuned to have an optimized jet spray for efficiently removing particles or contaminants from a surface of a wafer without causing any feature damage.

    摘要: The chemical-mechanical polishing (CMP) of products in general and semiconductor wafers in particular is controlled by monitoring the acoustic emissions generated during CMP. A signal is generated with the acoustic emissions which is reflective of the energy of the acoustic emissions. The signals are monitored and the CMP process is adjusted in response to a change in the acoustic emission energy. Changes in the acoustic emission energy signal can be used to determine the end-point for CMP, particularly when fabricating semiconductor wafers for planarizing/polishing a given surface thereof. Long-term changes in the acoustic emission energy signals resulting from process changes including, for example, wear of the polishing pad, can also be detected with the acoustic emission energy signals so that desired or necessary process adjustments, such as a reconditioning of the polishing pad, for example, can be effected or the process can be stopped or an alarm signal can be generated when unacceptable process abnormalities occur.

    摘要: An inventive edge cleaning device is provided for cleaning the edge a thin disc such as a semiconductor wafer. The inventive edge cleaning device has a sonic nozzle positioned so as to direct a liquid jet at the edge surface of the thin disc. Preferably the sonic nozzle is radially spaced from the thin disc's edge so that scrubbing, spin rinsing or spin cleaning may be simultaneously performed on the major surfaces of the thin disc as the thin disc edge is cleaned by the sonic nozzle. The liquid jet may include deionized water, NH4OH, KOH, TMAH, HF, citric acid, a surfactant, or other similar cleaning solutions, and the nozzle may remain stationary as the thin disc rotates or the nozzle may scan the circumference of the thin disc to clean the entire edge of the thin disc.

    摘要: A method and apparatus for cleaning wafer edges is provided. The inventive wafer cleaner employs a transducer equal in length to the diameter of a wafer to be cleaned, and positioned to direct sonic energy in line with the wafer's edge. Supporting and rotating mechanisms are positioned along the wafer's edge, outside of the transducer's high energy field, and preferably such that approximately 50 percent of the wafer is positioned between the wafer supports and the transducer. Therefore, minimal sonic energy is blocked from reaching the wafer's surface. The transducer dimensions relative to the wafer, and the positioning of the wafer supports relative to the transducer enable the system to achieve an approximately 50 percent edge cleaning duty cycle as the wafer is rotated.

    摘要: A single-substrate cleaning apparatus and method of use are described. In an embodiment of the present invention, a liquid cleaning solution is dispensed in small volumes to form a substantially uniform static liquid layer over a substrate surface by atomizing the viscous liquid with an inert gas in a two-phase nozzle. In another embodiment of the present invention, after a layer of the cleaning solution is formed over the substrate to be cleaned, acoustic energy is applied to the substrate to improve the cleaning efficiency. In a further embodiment, cleaning solution precipitates are avoided by dispensing de-ionized water with a spray nozzle to gradually dilute the cleaning solution prior to dispensing de-ionized water with a stream nozzle.

    摘要: Embodiments of the invention provide methods of applying a liquid to a backside of a substrate to bring the substrate to the temperature of the liquid. By controlling the temperature of the substrate the temperature of the semiconductor processing liquid may be maintained at a particular temperature or a type of reaction occurring in the semiconductor processing liquid may be enhanced or maintained, such as in reactions where relatively small amounts of liquid are used or expensive chemicals are used.
