摘要:
A device and a method for reducing particle exposure to substrates during thermal treatment are disclosed. Semiconductor wafers may be rotated on a device within a process chamber divided into two partial chambers such that a first partial chamber contains the substrate to be thermally treated and a second partial chamber contains at least parts of the rotation device. Between the partial chambers, a flow of gas is set such that gas from the second partial chamber is substantially prevented from passing into the first partial chamber. In this way, particles which are produced by rotation abrasion in the second partial chamber are largely prevented from passing onto the substrate to be thermally treated. This device and this method are particularly advantageous if the rotation is realized by means of a gas drive, wherein the gas used for the rotation can be introduced directly into the second partial chamber.
摘要:
Process and system for processing wafer-shaped objects, such as semiconductor wafers is disclosed. In accordance with the present disclosure, a multiple of two wafers are processed in a thermal processing chamber. The thermal processing chamber is in communication with at least one heating device for heating the wafers. The wafers are placed in the thermal processing chamber in a face-to-face configuration or in a back-to-back configuration.

摘要:
The aim of the invention is to reduce the formation of scratches in a device for the thermal treatment of substrates, in particular, semiconductor substrates, in a chamber in which the substrate is placed upon support elements. According to the invention, said aim is achieved by means of displaceable support elements.
摘要:
Disclosed is an apparatus and a method for reducing flash in an injection mold (532 or 542, 543) which molds a molded article between a first mold surface and a second mold surface. The apparatus includes an active material actuator (530 or 533a and 533b or 561a and 561b) configured to, in response to application or removal of an electrical actuation signal thereto, change dimension and urge the first mold surface relative to the second mold surface to reduce flash therebetween. The apparatus also includes a transmission structure (533) configured to provide in use, the electrical acutation signal to said active material actuator (530 or 533a and 533b or 561a and 561b) includes a set of active material actuators stacked one against the other to provide a varying sealing force to urge the first mold surface relative to the second mold surface.
摘要:
The invention relates to a device and a method for the heat treatment of substrates, especially semiconductor wafers. The device comprises a reaction chamber with a compensation element. According to the invention the substrate can be inserted and withdrawn again more easily by the fact that the compensation element (15) can be at least partly lowered and/or raised in the reaction chamber.
摘要:
The application relates to an apparatus for the heat treatment of disc shaped substrates, in particular semi-conductor wafers. The apparatus has at least one radiation source and a treatment chamber accommodating the substrate having an upper wall element and a lower wall element, at least one of the wall elements lying adjacent to the at least one radiation source and being substantially transparent for the radiation from the radiation source. Furthermore, the apparatus makes provision for at least a first gas inlet apparatus. The first gas inlet apparatus has a plate element which is disposed within the treatment chamber between the substrate and the upper wall element, a collar ring disposed between the plate element and the upper wall element, and a first gas conveyance duct extending at least partially within the treatment chamber. The plate element has a larger diameter than the substrate and in a hole region approximately corresponding to the diameter of the substrate a plurality of through holes. The collar ring surrounds the hole region and has at least one inlet opening. The first gas conveyance duct has an outlet which is aligned with the inlet opening of the collar ring, a gas flow flowing out of the outlet having a main flow direction which is directed past a centre point of the collar ring.
