Definitions

  • the invention relates to a method for cleaning, in particular for removing metallic contaminants and / or particles, from a plastic surface.
  • processors and integrated circuits are produced on silicon wafers in a multiplicity of different work steps to be carried out successively, in which the wafers are coated or exposed to a wide variety of materials, or parts of applied layers are removed again by different etching methods or other methods. Between these individual steps, the partially coated wafers must be transported from one processing machine to another machine. It is of utmost importance that the very delicate very filigree coated surfaces are not damaged. In particular, applied electrical conductor tracks must remain electrically separated from one another in order to ensure the functionality of the component to be produced, for example a processor.

  • PEEK polyetheretherketone
  • the invention achieves the stated object by a method for cleaning, in particular for removing metallic contaminants and / or particles, from a plastic surface, the method having the following steps: a) rinsing the plastic surface with deionized water,
  • the term "purging" is understood to mean that the respective liquid is applied to the plastic surface to be cleaned, for example by spraying the respective liquid onto the surface or by dipping the plastic surface into the respective liquid Of course, it is also possible to let the liquid run over the plastic surface.
  • the plastic surface to be cleaned is consequently rinsed with deionized water, which is also referred to as distilled water. This initially removes adhering or resting coarse particles on the surface. It is particularly advantageous that the ionized water is sprayed onto the plastic surface to be cleaned.
  • the plastic surface is rinsed with electrolyzed water. Electrolyzed water is produced by, for example, adding an electrolyte to deionized water and then passing it through an electrolytic cell. By using the electrolyzed water at least part of the adhering to the plastic surface metal is dissolved and removed in this way from the surface. Preferably, the adhered metal is completely removed.
  • the surface is rinsed again with deionized water in a third step.
  • a so-called “rinse cleaning process” is advantageously used in which the deionized water flows over the surface to be cleaned.
  • the inventive method makes use of the knowledge that the solubility of metals in water, in particular the pH and redox potential of the Water depends. Therefore, the solubility of the metals in electrolyzed water is usually higher than in deionized water, so that the additional process step of rinsing with electrolyzed water can better remove metallic contaminants than when purifying with deionized water alone.
  • rinsing with electrolyzed water involves rinsing with anodic water having a pH that is less than 7.
  • Anodic water is therefore acidic and can dissolve a variety of metals.
  • purging with electrolyzed water includes purging with cathodic water having a pH greater than 7.
  • particles, such as metallic particles may be at least mostly, but preferably completely, removed with cathodic water.
  • rinsing with electrolyzed water involves rinsing with both anodic and cathodic water, using the two differently electrolyzed water in succession.
  • the plastic surface is first rinsed with anodic water before it is rinsed with cathodic water. Rinsing the plastic surface with anodic water may leave slight positive charges on the surface. This facilitates later re-adhesion of particles and improves adhesion so that these remaining slightly positive charges should be avoided. Subsequent alkaline surface aftertreatment by cathodic water rinsing removes these slightly positive charges, making it difficult to adhere new particles.
  • deionized water is used for rinsing to remove as much as possible the residue of the electrolyzed water.
  • the electrolyzed water is produced in an electrolysis cell having two electrodes and into which water is added, which is treated with an electrolyte.
  • the production of electrolyzed water has been known for a long time from the prior art.
  • the pH and / or the redox potential of the electrolyzed water can be adjusted by using the concentration of the electrolyte and / or an electric current flowing between the two electrodes as control parameters.
  • the electrolysis cell generally has two electrolysis chambers, one of which represents the cathode chamber with the cathode located therein and the other represents the anode chamber with the anode located therein.
  • the two electrodes are formed as diamond electrodes.
  • the two chambers Into at least one of the two chambers is introduced with an electrolyte-added deionized water, which is thus exposed to the electric field that prevails between the two electrodes.
  • the two chambers are separated by a membrane which is permeable to ions of a given charge.
  • a membrane which is permeable to ions of a given charge.
  • the pH of the produced electrolyzed water can be adjusted to a predetermined value. If necessary, the residence time of the deionized water provided with electrolytes within the respective chamber of the electrolysis cell, ie the flow rate, and / or the current flowing through the two electrodes must be adjusted and adjusted.
  • the redox potential of the produced electrolyzed water can be adjusted by the electric current. It is thus possible to adjust both the pH and the redox potential independently of one another to a desired combination of values at least within predetermined ranges and thus optimally adjust the electrolyzed water to the metal to be dissolved, which adheres as an impurity to the plastic surface to be cleaned.
  • electrolytes can be selected which include chloride ions (Cl “ ), fluoride ions (F “ ), sulfate ions (SO 2 “ ), phosphate ions (PO 3” ), nitrate ions (NO 3 “ ) or It goes without saying that electrolytes which form cations in order to ensure electrical neutrality must also be used as cations, in particular hydrogen ions (H + ) and / or ammonium ions (NH4 + ).
  • the rinsing of the plastic surface in each of the process steps takes between 15 seconds and 90 seconds. If rinsing with both anodic and cathodic water in step b), a rinsing period between 15 seconds and 90 seconds can be provided for each of these two rinses. It has proven to be advantageous if the rinsing in the different process steps for different lengths lasts.
  • the respective rinsing time is set to the expected dirt or impurities and the desired degree of cleaning.
  • the temperature of the deionized water and / or the electrolyzed water may be between 10 ° C and 70 ° C. It has been shown that the cleaning effect increases with increasing temperature. Of course, the temperature in different process steps for the respective liquid can also be chosen differently here. In particular, the deionized water with which is flushed in step a), have a different temperature and in particular be warmer or colder than the deionized water with which in step c) is rinsed.
  • the invention also achieves the stated object by a device for carrying out a method described here.
  • a device for carrying out a method described here not only has the ability to rinse the plastic surface with the respective different liquids, but also includes an electrolytic cell to produce the required electrolyzed water itself.
  • the electrolysis cell can be operated continuously in permanent operation.
  • a temporally limited operation of the electrolytic cell may be useful if the device has, for example, one or more intermediate tanks or storage in which or which the electrolyzed liquid can be temporarily stored. In this case, it is possible to use a larger capacity electrolytic cell, which may be operated more efficiently if necessary.
