  • Patent number: 8097085
    Abstract: A frame supporting a containment chamber, the containment chamber is preferably configured to enclose and confine a process chamber. A heat source module is disposed between the containment chamber and the process chamber, while a thermal regulation cavity is maintained between the heat source module and the process chamber. Preferably, at least one fluid inlet box is in fluidic communication with the thermal regulation cavity, in which the fluid inlet box provides a plate valve that mitigates the flow of fluids from the thermal regulation cavity through the fluid inlet box and to an environment external to the thermal regulation cavity. Additionally, the preferred fluid inlet box further includes a flow adjustment structure interacting with the plate valve to control fluid flow from the environment external to the thermal regulation cavity past the plate valve and into thermal regulation cavity.

  • Publication number: 20120009536
    Abstract: A method is described for preheating annealing goods in a hood-type annealing installation, comprising two annealing bases (1, 2) which accommodate the annealing goods (3, 4) under a protective cover (7, 8), with the annealing goods (3) to be subjected to a heat treatment under a protective cover (8) being preheated with the help of a gaseous heat carrier which is guided in a cycle between two protective covers (7, 8) and absorbs heat from annealing goods (4) which are heat-treated in a protective cover (7) and emits it to the annealing goods (3) to be preheated in the other protective cover (8). In order to avoid contaminations of the heat-treated annealing goods (4) it is proposed that the heat carrier flow guided in a cycle flows around the two protective covers (7, 8) on the outside, whereas a protective gas is circulated within the protective covers (7, 8).

  • Publication number: 20120006579
    Abstract: An electric wire comprises a non-oxidized conductor of copper alloy having no outer coating and in direct contact with a PTFE-based sheath. It is fabricated as follows: providing a copper alloy conductor without an outer coating; forming a sheath of a PTFE-based material around the conductor; and heating the wire in order to evaporate the lubricant and sinter the sheath. In order to avoid oxidizing the copper during the heating step, the wire is heated mainly in an atmosphere having a low oxygen content. The lubricant evaporation and/or sintering line for stabilizing the sheath of the electric wire comprises one or more ovens, each having an enclosure in which an atmosphere having a low oxygen content is maintained.

  • Patent number: 8029274
    Abstract: A convection oven with laminar airflow and/or moisture injection. A radial airflow fan is used to provide a circulating airflow that is substantially even and substantially turbulence free. The circulating airflow is provided to an oven chamber via a plurality of egress ports that rim a divider wall disposed between the oven chamber and a fan chamber. The airflow interleaves with a plurality of pans in the oven chamber to provide a laminar airflow. Moisture is injected into the circulating airflow either upstream of the fan or by flashing water onto the hot blades of the fan from either the low pressure side or the high pressure side of the fan.

  • Patent number: 7939456
    Abstract: A microwave heating system comprises a microwave applicator cavity; a microwave power supply to deliver power to the applicator cavity; a dielectric support to support a generally planar workpiece; a dielectric gas manifold to supply a controlled flow of inert gas proximate to the periphery of the workpiece to provide differential cooling to the edge relative to the center; a first temperature measuring device configured to measure the temperature near the center of the workpiece; and, a second temperature measuring device configured to measure the temperature near the edge of the workpiece. The gas flow is controlled to minimize the temperature difference from center to edge, and may be recipe driven or controlled in real time, based on the two temperature measurements. The method is particularly useful for monolithic semiconductor wafers, various semiconducting films on substrates, and dielectric films on semiconducting wafers.
