  • Publication number: 20100072169
    Abstract: Methods for preventing feature collapse subsequent to etching a layer encasing the features include adding a non-aqueous liquid to a microelectronic topography having remnants of an aqueous liquid arranged upon its surface and subsequently exposing the topography to a pressurized chamber including a fluid at or greater than its saturated vapor pressure or critical pressure. The methods include flushing from the pressurized chamber liquid arranged upon the topography and, thereafter, venting the chamber in a manner sufficient to prevent liquid formation therein. The topography features may be submerged in a liquid while pressurizing the chamber. A process chamber used to prevent feature collapse includes a substrate holder for supporting a microelectronic topography, a vessel configured to contain the substrate holder, and a sealable region surrounding the substrate holder and the vessel. The chamber is configured to sequester wet chemistry supplied to the vessel from metallic surfaces of the sealable region.

  • Patent number: 7682462
    Abstract: A cluster tool includes a transfer chamber connected to a plurality of vacuum chambers. An additional process chamber connected to the transfer chamber includes a high pressure chamber assembly seated on a housing. The high pressure chamber assembly, which is adjustable between an open position and a closed position, includes an upper chamber portion and a lower chamber portion. Hydraulic cylinders mounted on the upper chamber portion and having chamber rods that attach to the lower chamber portion are configured to move the lower chamber relative to the upper chamber portion between the two positions. When the two portions are brought together into the closed, the high pressure chamber assembly forms a high pressure chamber suitable for processing wafers with supercritical CO2. Once the high pressure chamber is formed, a region between lower chamber portion and a housing may be evacuated to form a vacuum chamber outside a portion of the high pressure chamber.

  • Patent number: 6601824
    Abstract: A single slot valve shaft is in a vacuum body between adjacent vacuum chambers, such as a process module and a transport module. Separate valves are provided on the single shaft actuator for each of two valve body slots, each body slot being closed or opened according to the position of the single shaft. The separate valves allow a vacuum condition to be maintained in the transport module while an adjacent process module is open to the atmosphere for servicing. The single shaft allows access to an open valve for servicing the open valve by way of stops that limit drive travel and hold the valve in an open, but not vertically-spaced, position relative to a respective slot. The open valve is easily reached by a gloved hand of a service worker. The single shaft is mounted on a first cradle, and the first cradle is mounted on a second cradle. Two separate shaft drives move the two cradles to position the single shaft to locate the valves between the slots to open one slot and close the other slot.

  • Patent number: 6494670
    Abstract: A functional load lock apparatus having two or more load lock chambers mounted on a central chamber which can be mounted on a single opening in a vacuum chamber such as a substrate processing platform for making integrated circuits on silicon wafers. Each load lock chamber preferably has a semi-cylindrical valve which remains sealed when the load lock chamber is open to atmospheric pressure. A wafer cassette holder positioned within each load lock chamber can be loaded and unloaded while the semi-cylindrical valves seal the vacuum chamber from atmospheric pressure. The semi-cylindrical valve pivots to an open position when the load lock chamber is under vacuum and the entire wafer cassette moves from the load lock chamber to the central chamber.

  • Patent number: 6244811
    Abstract: A load lock wafer transfer face is provided at an acute angle with respect to a footprint dimension line, so the length of the footprint dimension line does not include the entire minimum length of the wafer transfer distance that must separate a robot from the wafer transfer face of a load lock. Two adjacent load locks provided for use with a robot have two load lock wafer transfer faces defining a nest, in that each such face is at an acute angle with respect to the footprint dimension line. A robot is mounted for rotation at a fixed location relative to wafer cassettes and to the nested load lock wafer transfer faces, avoiding use of a robot track to move transversely. Because the faces are at the acute angle, there is only a component of, and not the entire, minimum wafer transfer distance extending in the direction of the footprint dimension line.

  • Patent number: 6095741
    Abstract: A dual sided slot valve is in a vacuum body between adjacent process and transport modules. Separate valves are provided for each of two valve body slots, one body slot being separately closed or opened independently of the other. The separate valves allow a vacuum in the transport module while an adjacent process module is open to the atmosphere for servicing. The valve allows access to an open valve for servicing the open valve in that one actuator motor stops the valve in an open, but not vertically-spaced, position relative to the respective slot. The open valve is more easily reached by a gloved hand of a service worker. A separate actuator motor moves the valve vertically down from the open position and away from the slot to expose the sealing surface around the slot for cleaning. The vertical distance of the vertically-moved valve from an access opening makes it difficult for the worker's glove to reach the valve for service.

  • Patent number: 6056504
    Abstract: An adjustable length frog-leg type wafer handler is provided. The wafer handler has two arms each having an upper portion and a lower portion. The lower portion may extend between a normal position and an extended position, and/or the upper portion may extend between an normal position and a compressed position. The adjusted positions (i.e., extended or compressed) are assumed as the wafer handler moves through a center position. Thus, the inventive wafer handler has a normally smaller arm length (as compared to conventional frog leg configurations) which in turn allows a smaller core axis of rotation (i.e., a smaller bladeless arm length). Therefore the blade used with the adjustable wafer handler may be longer by an amount equal to the difference between the normal and the adjusted arm lengths, without increasing the overall (i.e., the length of the arm and blade) retracted axis of rotation.

  • Patent number: 6000227
    Abstract: A vacuum processing system has a wafer cooling system disposed on a lid of a transfer chamber so that heated wafers are cooled inside the transfer chamber. The wafer cooling system has a wafer lift assembly and a wafer cooler. The wafer cooler has a cooling plate and a coolant tank disposed through the transfer chamber lid. The wafer lift assembly has a lift actuator disposed on the top of the transfer chamber lid, guide rods to translate the lifting motion through the lid, and wafer supports inside the lid to raise the wafer to a position proximate to the cooling plate. The wafer cools by radiating heat up to the cooling plate, and the coolant tank transfers the heat from the cooling plate.
