  • Publication number: 20180261473
    Abstract: A heater or cooler vacuum chamber for degassing includes an enclosure and within the enclosure a controllably heatable or coolable pocket. Within the pocket is a workpiece holder and a gas feedline discharging the pocket. The inner surface of the pocket surrounds the workpiece in a closely spaced manner. The two halves forming the pocket may be controllably separate so as to allow a gas flow connection which establishes a negligible gas flow restriction to the remainder of the enclosure.

  • Patent number: 10066287
    Abstract: Liquid precursor material of a coating substance and a solvent is provided in a reservoir (STEP1, STEP1?). In one variant the liquid precursor material is distilled (STEP2), the resultant liquid coating substance is vaporized (STEP3) and ejected through a vapor distribution nozzle arrangement (7) into a vacuum recipient (3) and onto substrate 5 to be coated. Alternatively, the liquid precursor material is directly vaporized (STEP3?). From the two-component vapor coating substance vapor is applied to substrate 5? to be coated. In this variant separation of solvent vapor and coating substance vapor is performed especially downstream vaporizing (STEP2?).
