摘要： X-ray lithographic systems as heretofore constructed include a low-attenuation chamber for propagating x-rays from a source toward a mask member that is positioned in close proximity to a resist-coated wafer. Both the mask and the wafer are included in the chamber which typically is either filled with helium or evacuated to a pressure less than about 10.sup.-2 Torr. In accordance with this invention, an x-ray lithographic system is constructed to enable establishment in the wafer-to-mask region of a controlled atmosphere that is separate and distinct from that maintained in the low-attenuation chamber. In this way, an improved lithographic system with advantageous throughput and other characteristics is realized.

摘要： In an integrated circuit fabrication sequence, a relatively thick sacrificial layer (18) is deposited on a nonplanar surface of a device wafer in which high-resolution features are to be defined. The thick layer is characterized by a conforming lower surface and an essentially planar top surface and by the capability of being patterned in a high-resolution way. An intermediate masking layer (22) and then a thin resist layer (20) are deposited on the top surface of the sacrificial layer, the thickness of the resist layer being insufficient by itself to provide adequate step coverage if the resist layer were applied directly on the nonplanar surface. A high-resolution pattern defined in the resist layer is transferred into the intermediate masking layer. Subsequently, a dry processing technique is utilized to replicate the pattern in the sacrificial layer. A high-resolution pattern with near-vertical sidewalls is thereby produced in the sacrificial layer. By means of the patterned sacrificial layer, high-resolution features are then defined in the underlying nonplanar surface.

摘要： An apparatus and method for reducing the production of white powder in a process chamber used for depositing silicon nitride. Steps of the method include heating at least a portion of a wall of the process chamber; providing a liner covering a substantial portion of a wall of the process chamber; providing a remote chamber connected to the interior of the process chamber; causing a plasma of cleaning gas in the remote chamber; and flowing a portion of the plasma of cleaning gas into the process chamber. The apparatus includes a deposition chamber having walls; means for heating the walls, the means thermally coupled to the walls; a liner covering a substantial portion of the walls; a remote chamber disposed outside of the chamber; an activation source adapted to deliver energy into the remote chamber; a first conduit for flowing a precursor gas from a remote gas supply into the remote chamber where it is activated by the activation source to form a reactive species; and a second conduit for flowing the reactive species from the remote chamber into the deposition chamber.

摘要： An inlet gas manifold for a vacuum deposition chamber incorporates inlet apertures which increase in diameter or cross-section transverse to the direction of gas flow. The aperture configuration increases the dissociation gases such as nitrogen and, thus increases the rate of silicon nitride deposition provided by nitrogen gas chemistry, without requiring the use of reactants such as ammonia. While one could use ammonia in the deposition gas chemistry if desired, the process provides the option of completely eliminating ammonia. The inlet manifold containing the increasing-diameter gas inlet holes provides enhanced control of the process and the deposited film, and is also useful for forming other dielectrics such as silicon oxide and silicon oxynitride. In particular, silicon oxynitride films are characterized by low hydrogen content and by compositional uniformity.

摘要： The present invention discloses a two basic structures (including multiple variations within one of the basic structures) and methods for fabrication of the structures which facilitate the flow of cooling gas or other heat transfer fluid to the surface of an electrostatic chuck. The basic structures address both the problem of breakdown of a heat transfer gas in an RF plasma environment and the problem of arcing between a semiconductor substrate and the conductive pedestal portion of the electrostatic chuck in such an RF plasma environment.

摘要： An integrated modular multiple chamber vacuum processing system is disclosed. The system includes a load lock, may include an external cassette elevator, and an internal load lock wafer elevator, and also includes stations about the periphery of the load lock for connecting one, two or several vacuum process chambers to the load lock chamber. A robot is mounted within the load lock and utilizes a concentric shaft drive system connected to an end effector via a dual four-bar link mechanism for imparting selected R-.theta. movement to the blade to load and unload wafers at the external elevator, internal elevator and individual process chambers. The system is uniquely adapted for enabling various types of IC processing including etch, deposition, sputtering and rapid thermal annealing chambers, thereby providing the opportunity for multiple step, sequential processing using different processes.
