Abstract: Each of a plurality of individually heated circularly located susceptors supports and heats one of a plurality of wafers within a processing chamber. An overhead gas dispersion head, vertically aligned with each susceptor, directs, in combination with downstream flow control structure, flow of a reactant gas radially uniformly across the supported wafer. A spider sequentially relocates each of the wafers, as a group, to an adjacent susceptor. Wafer handling apparatus replaces each processed wafer to provide a high production rate throughput. A source of RF energy radiating essentially primarily between each gas dispersion head and its associated susceptor provides a plasma enhanced environment and the low level intensity elsewhere within the reactor reduces residual deposits.

Abstract: Laser excimeur à oscillation à bande étroite utilisant une grille de diffraction en tant qu'élément sélecteur de longueur d'onde, particulièrement indiqué pour une source de lumière d'un dispositif d'alignement du type à réduction. La grille utilisée dans le laser susmentionné est positionnée de sorte que la direction de ses lignes est presque perpendiculaire à la direction de la décharge du laser. Lorsque l'on utilise un expandeur de faisceau pour diffuser le faisceau laser tombant sur la grille, l'expandeur est disposé de sorte que la direction de diffusion du faisceau est presque perpendiculaire à celle de décharge du laser. En outre, lorsqu'on doit utiliser une ouverture dans le résonateur optique, l'ouverture est placée de sorte que le sens de la longueur puisse être parallèle à la direction de décharge du laser. En outre, le miroir antérieur du résonateur optique est cylindrique, et son axe mécanique est parallèle à la direction de décharge du laser. Cet agencement permet de produire un appareil laser excimeur à oscillation à bande étroite présentant un très grand rendement et une excellente durée.

Abstract: Une structure de données possède un champ de valeurs pour stocker des valeurs et un champ de fermeture pour indiquer un état verrouillé de la ressource associée à la structure de données. Cette structure de données est utilisée pour mettre en oeuvre un protocole de verrouillage parmi des processus multiples en concurrence pour des ressources partagées. Si le champ de verrouillage se trouve dans un état verrouillé, le procédé qui a verrouillé le champ possède un accès exclusif à la ressource. Cependant, si le champ de verrouillage se trouve dans un état non verrouillé, tout procédé peut avoir accès à la ressource. Le champ de verrouillage possède également des états différés correspondant aux états verrouillés et non verrouillés selon lesquels des demandes multiples pour verrouiller et déverrouiller la ressource peuvent être mémorisées jusqu'à leur utilisation. Le protocole de verrouillage est utile dans un système de traitement de données ayant de multiples éléments de traitement et utilise un moyen de verrouillage qui comprend une unité de commande de mémoire locale.
