  • Patent number: 7947605
    Abstract: A method is described for use in a system that removes an implant crust that is formed as an outermost layer of photoresist in a photoresist pattern that is supported by a workpiece. The photoresist pattern defines apertures which lead to an active device region. The active device region is formed by an ion implantation which produces the implant crust. A filler material is applied such that the filler material reaches a fill depth in each aperture. The workpiece and the filler material are exposed to a treatment environment to remove the implant crust on the laterally extending surface of the photoresist as the filler material protects the active device region. Thereafter, a remaining portion of the photoresist layer is removed. An associated intermediate assembly, including the workpiece, is described.

  • Publication number: 20100252547
    Abstract: An approach for optimizing the thermal budget during a pulsed heating process is disclosed. A heat sink or thermal transfer plate is configured and positioned near an object, such as a semiconductor wafer, undergoing thermal treatment. The heat sink is configured to enhance the thermal transfer rate from the object so that the object is rapidly brought down from the peak temperature after an energy pulse. High thermally-conductive material may be positioned between the plate and the object. The plate may include protrusions, ribs, holes, recesses, and other discontinuities to enhance heat transfer and avoid physical damage to the object during the thermal cycle. Additionally, the optical properties of the plate may be selected to allow for temperature measurements via energy measurements from the plate, or to provide for a different thermal response to the energy pulse. The plate may also allow for pre-heating or active cooling of the wafer.

  • Patent number: 7799685
    Abstract: In a technique for fabricating an integrated circuit to include an active device structure which supports an electrical interconnect structure, a photoresist layer is used prior to forming an electrical interconnect structure on the active device structure. The photoresist and related residues are removed by exposing the photoresist and exposed regions of the active device structure to one or more reactive species that are generated using a gas mixture including hydrogen gas, as a predominant source of the reactive species, in a plasma source such that the photoresist and residues are continuously exposed to hydrogen-based reactive species. An associated system architecture is described which provides for a substantial flow of hydrogen gas in the process chamber.

  • Patent number: 7737385
    Abstract: A customizable chamber spectral response is described which can be used at least to tailor chamber performance for wafer heating, wafer cooling, temperature measurement, and stray light. In one aspect, a system is described for processing a treatment object having a given emission spectrum at a treatment object temperature which causes the treatment object to produce a treatment object radiated energy. The chamber responds in a first way to the heating arrangement radiated energy and in a second way to the treatment object radiated energy that is incident thereon. The chamber may respond in the first way by reflecting the majority of the heat source radiated energy and in the second way by absorbing the majority of the treatment object radiated energy. Different portions of the chamber may be treated with selectively reflectivity based on design considerations to achieve objectives with respect to a particular chamber performance parameter.

  • Patent number: 7658586
    Abstract: A wafer processing system and method in which a wafer, having a diameter, is movable between a loadlock and a processing chamber. A transfer chamber is arranged for selective pressure communication with the loadlock and the processing chamber. The transfer chamber having a configuration of lateral extents such that the wafer is movable through the transfer chamber between the loadlock and processing chamber along a wafer transfer path and the configuration of lateral extents causes the wafer, having the wafer diameter and moving along the wafer transfer path, to interfere with at least one of the loadlock and the processing chamber for any position along the wafer transfer path. The wafer includes a center and the wafer transfer path cab be defined by movement of the center through the transfer chamber. Swing arms are described that can independently move by different angles in opposing directions from a home position.

  • Patent number: 7654596
    Abstract: Various endeffector designs are disclosed for handling semiconductor wafers. For instance, an endeffector for handling wafers at a relatively low temperature is disclosed along with an endeffector for handling wafers at a relatively high temperature. Both endeffectors include uniquely designed support members that are configured to only contact a wafer at the wafer's edge. The endeffectors may also include a wafer detection system. The endeffector for handling wafers at relatively low temperatures may also include a pushing device that is used not only to position a wafer but to hold a wafer on the endeffector during acceleration or deceleration of the endeffector caused by a robot arm attached to the endeffector. As designed, the endeffectors may have a very slim profile making the endeffectors easily maneuverable.

  • Patent number: 7642205
    Abstract: A method that is performed for heat treating a semiconductor wafer in a process chamber, as an intermediate part of an overall multi-step technique for processing the wafer, includes applying an energy transfer layer to at least a portion of the wafer, and exposing the wafer to an energy source in the process chamber in a way which subjects the wafer to a thermal profile such that the energy transfer layer influences at least one part of the thermal profile. The thermal profile has at least a first elevated temperature event. The method further includes, in time relation to the thermal profile, removing the energy transfer layer in the process chamber at least sufficiently for subjecting the wafer to a subsequent step. An associated intermediate condition of the wafer is described.

  • Patent number: 7563068
    Abstract: As part of a system for processing workpieces, a workpiece support arrangement, separate from a process chamber arrangement supports at least two workpieces at least generally in a stacked relationship to form a workpiece column. A transfer arrangement transports at least two of the workpieces between the workpiece column and the process chamber arrangement by simultaneously moving the two workpieces at least generally along first and second transfer paths, respectively, that are defined between the workpiece column and the first and second process stations. The transfer arrangement can simultaneously move untreated and treated workpieces. Vertical motion swing arms and coaxial swing arms are described. A pair of spaced apart swing arms, the workpiece column and the processing stations can cooperatively define a pentagonal shape. Timing belt backlash elimination, a dual degree of freedom slot valve and low point chamber pumping, for removing chamber contaminants, are also described.

  • Patent number: 7543981
    Abstract: Methods and apparatus for wafer temperature measurement and calibration of temperature measurement devices may be based on determining the absorption of a layer in a semiconductor wafer. The absorption may be determined by directing light towards the wafer and measuring light reflected from the wafer from below the surface upon which the incident light impinges. Calibration wafers and measurement systems may be arranged and configured so that light reflected at predetermined angles to the wafer surface is measured and other light is not. Measurements may also be based on evaluating the degree of contrast in an image of a pattern in or on the wafer. Other measurements may utilize a determination of an optical path length within the wafer alongside a temperature determination based on reflected or transmitted light.
