Generally, the antenna arrangement (210) comprises an outer loop (610), comprising a first outer loop turn (618) disposed around an antenna axis (614), an inner loop (606), comprising a first inner loop turn (616) disposed around the antenna axis (614), wherein the inner loop (606) is closer to the antenna axis (614) than the outer loop (610) is to the antenna axis (614) in each azimuthal direction, and a radial connector (640) radially electrically connecting the outer loop (610) to the inner loop (606), wherein the radial connector (640) is placed a large distance from the window (212).
Abstract:
A system and method for planarizing a patterned semiconductor substrate (100) includes receiving a patterned semiconductor substrate. The patterned semiconductor substrate (100) having a conductive interconnect material (120) filling multiple of features in the pattern. The conductive interconnect material has an overburden portion (112). The overburden portion has a localized non-uniformity. A bulk portion of the overburden portion is removed to planarize the overburden portion (120). The substantially locally planarized overburden portion is mapped to determine a global non-uniformity. The substantially locally planarized overburden portion is etched to substantially remove the global non-uniformity.
Abstract:
An apparatus and method for adjusting the voltage applied to a Faraday shield (112) of an inductively coupled plasma etching apparatus (101) is provided. An appropriate voltage is easily and variably applied to a Faraday shield such that sputtering of a plasma can be controlled to prevent and mitigate deposition of non-volatile reaction products that adversely affect an etching process. The appropriate voltage for a particular etching process or step is applied to the Faraday shield by simply adjusting a tuning capacitor (204, 210, 208, 206). It is not necessary to mechanically reconfigure the etching apparatus to adjust the Faraday shield voltage.
Abstract:
Methods and systems to optimize wafer placement repeatability in semiconductor manufacturing equipment using a controlled series of wafer movements are provided. In one embodiment, a preliminary station calibration is performed to teach a robot position for each station interfaced to facets of a vacuum transfer module used in semiconductor manufacturing. The method also calibrates the system to obtain compensation parameters that take into account the station where the wafer is to be placed, position of sensors in each facet, and offsets derived from performing extend and retract operations of a robot arm. In another embodiment where the robot includes two arms, the method calibrates the system to compensate for differences derived from using one arm or the other. During manufacturing, the wafers are placed in the different stations using the compensation parameters.
Abstract:
A bevel inspection module for capturing images of a substrate is provided. The module includes a rotational motor, which is attached to a substrate chuck and is configured to rotate the substrate chuck thereby allowing the substrate to revolve. The module further includes a camera and an optic enclosure, which is attached to the camera and is configured to rotate, enabling light to be directed toward the substrate. The camera is mounted from a camera mount, which is configured to enable the camera to rotate on a 180 degree plane allowing the camera to capture images of at least one of a top view, a bottom view, and a side view of the substrate. The module yet also includes a backlight arrangement, which is configured to provide illumination to the substrate, thereby enabling the camera to capture the images, which shows contrast between the substrate and a background.
Abstract:
