  • Patent number: 8569425
    Abstract: The present invention relates to modified phenolic resins which contain silicic acid ester units. The modified phenolic resins may, for example, be used as components of a foundry binder system. The invention also relates to a method for producing such modified phenolic resins and to two-component binder systems which contain these modified phenolic resins. The invention furthermore relates to methods for producing foundry molds and foundry cores which contain the modified phenolic resins, and to the foundry molds and foundry cores themselves.

  • Publication number: 20040231971
    Abstract: The invention relates to a photo mask blank, a photo mask, a method and an apparatus for manufacturing a photo mask blank in general, and for manufacturing a photo mask blank by particle beam sputtering in particular. It is an object of the invention to provide a method of manufacturing a photo mask blank of high quality and high stability that is suitable for the production of a photo mask having small structures. The invention proposes a method for manufacturing a photo mask blank, wherein a substrate and a target are provided in a vacuum chamber. The target is sputtered by irradiating with a first particle or ion beam and at least a first layer of a first material is deposited on the substrate by the sputtering of said target.
