摘要:
Wafer protecting grooves (10) are provided on an innermost wall (1b) of a container body (1). The wafer protecting grooves have a cross-sectional configuration in the shape of undulations having bottoms (10b), which are most distant from an opening (1a), at respective positions facing the outer edges of semiconductor wafers (W), and having an opening width wider than the thickness of each semiconductor wafer (W). In a normal state, an imaginary line (Q) connecting together the tops of the undulations is inward of or at the same position as the outer edges of the semiconductor wafers (W) facing the imaginary line. Thus, it is possible to obtain superior impact resistance that makes the semiconductor wafers (W) in the container body (1) unlikely to be damaged even when a large impact is applied thereto by a fall or other handling errors.

摘要:
Improvements in a semiconductor wafer container including improvements in side protection to the wafers, improved cover design to minimize rotation, a simplified top cover orientation mechanism and an improved bottom holding mechanism for automation. The side protection to the wafers is with multiple staggered inner and outer walls. The improved cover design improves alignment of the top and bottom housings and minimizes rotation of the housings in transit or motion. The housings have a recessed tab ramp feature with bi-directional locking that also increases the rigidity of the containment device when the two housings are assembled. The improved bottom holding mechanism for automation is an integrated feature that is molded into the bottom housing and not assembled in a secondary operation. The molded integration reduces tolerance errors that are present in assembling multiple pieces and joining multiple pieces.

Techniques associated with higher performance barrier materials for containers to contain one or more environmentally sensitive devices associated with semiconductor manufacture are generally described. In one example, an apparatus includes an enclosure to contain one or more environmentally sensitive devices associated with semiconductor manufacture, the enclosure comprising a liquid crystal polymer (LCP) to provide a barrier against at least water and oxygen and to reduce purging requirements, and a door coupled with the enclosure.
摘要:
A wafer container made from a polymer material with inner walls of the container coated with a thin easily washable wear-resistant and scratch-resistant barrier layer of SiO2 for preventing penetration of products of diffusion of polymers, such as free radicals, into the interior space of the carrier that retains a wafer. The SiO2 coatings on the walls of the container are applied by the PECVD process. The wafer container of the invention can be manufactured at low cost by molding it from a less expensive and lower grade polymer.

A substrate mounting stage that prevents poor attraction of substrates so as to improve the operating rate of a substrate processing apparatus. The substrate mounting stage is disposed in the substrate processing apparatus and has a substrate mounting surface on which a substrate is mounted. The arithmetic average roughness (Ra) of the substrate mounting surface is not less than a first predetermined value, and the initial wear height (Rpk) of the substrate mounting surface is not more than a second predetermined value.

A composite wafer carrier according to an embodiment of the present invention comprises an operative portion formed of a first thermoplastic material and a support portion formed of a second different thermoplastic material. One of the operative portion and support portion is overmolded onto the other to form a gapless hermitic interface that securely bonds the portions together. The operative portion may be a transparent window, a portion of a latching mechanism or a wafer contact portion. Preferred embodiments of the invention include wafer carriers with said features, process carriers with said features and a process for manufacturing wafer carriers with said features.

The invention relates to transport and shipping containers for wafers that are processed into semiconductor units. The wafer transport system provides wafer carriers that provide damage protection and particulate protection with minimal contamination of the wafers in the shipper. The invention includes a wafer cushion for cushioning semiconductor wafers that is made of a closed-cell polyethylene material with a surface resistivity of less than 5×107 ohms per square that has less than 1800 ng/g Cl−, 400 ng/g F−/Acetate, 270 ng/g NO3−, 350 ng/g SO42−, and 60 ng/g PO43−ions leachable under moderate conditions. The wafer cushion optimally has no detectable outgassing organics under stringent conditions. The static control properties are the result of carbon that is part of the structure of the material.
摘要:
A method of using a substrate transport pod is suitable for manufacturing semiconductor devices with copper wiring and low dielectric insulating film having dielectric constants of less than 3. The method is based on loading the substrates into a pod from an atmosphere of a first process, and circulating a gaseous atmosphere through interior of the pod in such a way to selectively remove at least one contaminant including moisture, particulate substances or chemical substances, and to expose the substrates to a controlled atmosphere intermittently or continually while the substrates are held in the pod before they are unloaded from the pod and introduced into a second process. For a pod that is used to house the substrates for the purpose of retaining or transporting, the pod has a pod main body and a door that provides a hermetic seal, the pod is made primarily of a materiel that has moisture absorption factor of less than 0.1 %, the pod can contact the substrates directly or indirectly and has a conductive area so as to enable static charges to be guided out of the pod.
