摘要： A semiconductor processing chamber having a plurality of ribs on an exterior surface of the chamber is provided. The ribs are positioned relative to the chamber such that shadows cast into the chamber by the ribs are offset from one another, thus more uniformly distributing radiant energy entering the chamber. In one embodiment, the ribs are positioned on the exterior surface of the chamber so that they have dissimilar radial distances from a center of the chamber. When a substrate rotates within the chamber, shadows produced by the ribs on a first side of the chamber fall substantially between secondary shadows produced by the ribs on a second side of the chamber. Likewise, shadows produced by the ribs on the second side of the chamber fall substantially between the secondary shadows produced by the ribs on the first side of the chamber.
摘要翻译：提供了在腔室的外表面上具有多个肋的半导体处理室。肋相对于室定位，使得通过肋投射到室中的阴影彼此偏移，从而更均匀地分布进入室的辐射能。在一个实施例中，肋被定位在腔室的外表面上，使得它们与腔室的中心具有不同的径向距离。当衬底在室内旋转时，腔室第一侧上的肋产生的阴影基本上落在腔室第二侧上由肋产生的次级阴影之间。类似地，由室的第二侧上的肋产生的阴影基本上落在由室的第一侧上的肋产生的次级阴影之间。

摘要： The process tube of a vertical heat-treating apparatus for semiconductor wafers has a port at the bottom to be opened and closed by a lid. A sealing mechanism is arranged to seal the connecting portion between the flange of the port and the flange of the lid. The flanges are provided with annular mirror surfaces on the inner side, which face and contact each other to form an inner seal. The flanges are also provided with annular counter surfaces on the outer side, which face each other with a gap therebetween. A metal sheet member is arranged in the gap such that an outer seal is formed by the metal sheet member and the counter surfaces. The metal sheet member has sheets vacuum-stuck onto the counter surfaces, respectively. A buffer space is formed between the inner and outer seals, and is vacuum-exhausted by an exhaust unit.

The lower end of the outer wall being fused to the outer surface of the thickened annular junction. The outer surface of the inner wall and the inner surface of the annular junction flange define a sloping annular drainage channel to a downwardly sloping drainage port, enabling liquid to drain from the junction. The double wall reaction chamber assembly has a cylindrical inner wall and a cylindrical outer wall axially parallel thereto. It has a lower end fused to the inner wall. A gas distribution tube has a gas inlet end and a gas distributor end, the gas distributor end comprising a split tee having a junction. One leg of the tee extends in a first direction from the junction around the inner wall to a first outlet terminus, and the other leg of the tee extends from the junction in a second direction around the inner wall in a direction opposite to the first direction and to a second outlet terminus. The legs of the tee slope downward from the junction to the respective outlet terminus, whereby liquid in the gas distributor will completely drain from the assembly.

摘要： A vertical semiconductor wafer processing furnace that includes a single housing having first and second vertical furnaces each having a heating chamber for heat treating a semiconductor wafer. The first and second vertical furnaces are asymmetrically disposed relative to each other to reduce the overall footprint of the processing furnace. Each vertical furnace includes a wafer support assembly that includes support structure, such as a wafer boat, boat elevator, motor and guide rod, for axially mounting a selected number of semiconductor wafers. A translation element selectively moves one of the support elements along the vertical axis into and out of the process tube, and a wafer transfer element selectively transfers semiconductor wafers to or from one of the support elements. The furnace further includes a heating sleeve or envelope that is adapted to control the ambient fluid environment surrounding the support structure and which is independently movable relative to support structure. The heating sleeve is adapted to sealingly engage a portion of the support element to create a fluid-tight seal forming a loadlock processing assembly. This assembly is coupled to a vertical translation assembly that selectively, vertically moves the processing assembly into the heating chamber of the vertical furnace. Additionally, the heating sleeve an be vertically moved relative to the support structure to engage and disengage repetitively, easily and automatically the heating sleeve relative to the support structure.

摘要： A vertically oriented thermal processor supports semiconductor wafers within a vertical process chamber within a process tube about which a furnace heater is supported. A base plate support assembly mates with a processing vessel such that the interior surface in proximate fluid adjoining relation with the processing chamber is formed from substantially-inert materials. Additionally, the base plate support assembly includes fluid cooling features that protect seals formed by devices passing through the base plate assembly into the processing chamber for delivery of processing gases and monitoring of thermal conditions therein. Additionally, cooling features are provided in a base plate in order to prevent components from becoming heat sinks or heat sources in relation to the processing chamber.

摘要： Performance of a high temperature diffusion furnace is enhanced by an improved multi-furnace module design. The furnace is constructed of materials suitable for clean room environments with an adjustable leveling frame assembly. A slide out assembly and heating element alignment mechanism of individual furnace tube modules with a heating element hoist mechanism allows for enhanced maintainability. Heat treatment performance is improved by a sealed heating element with individual furnace module cooling system. Improved thermocouple positioning and composition has also enhanced heat treatment process control and heating element maintainability.

摘要： A solid metal-gettering material is used between walls of a double-walled processing chamber, such as a furnace tube and an RTP chamber. The solid metal-gettering material getters metal before the metal reaches the substrate within the processing zone of a the processing chamber. Polysilicon pellets and silicon carbide pellets are examples of types of solid metal-getting materials, although other materials may be used. A purge gas may be flow within the gap or the gap may be evacuated while the pellets lie within the gap. Limitations on shapes and sizes of the pellets and purge gas flow rate are determined by the size of the gap.
