摘要:
A method for aligning a substrate to a process center of a support mechanism is provided. The method includes determining substrate thickness after substrate processing at a plurality of orientations and at a plurality of radial distances from a geometric center of the substrate. The method also includes deriving a set of process rate values from substrate thickness and process duration. The method further includes creating for a process rate an off-centered plot which represents a substantially concentric circle whose points are a circumference of the off-centered plot having substantially the first process rate. The method yet also includes applying a curve-fitting equation to the off-centered plot to determine a set of parameters. The method yet further includes teaching a set of robot arms the set of parameters, thereby enabling the set of robot arms to align another substrate that is supported by the support mechanism with the process center.

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.

A method for calculating a process center for a chuck in a processing chamber is provided. The method includes generating pre-processing and post-processing measurement data points, which is perform by measuring thickness of a film substrate at a set of orientations and a set of distances from a geometric center of the substrate. The method also includes comparing the pre-processing and post-processing measurement data points to calculate a set of etch depth numbers. The method further includes generating etch profiles for the set of orientations. The method yet also includes extrapolating a set of radiuses, which is associated with a first etch depth, from the etch profiles. The method yet further includes generating an off-centered plot, which is a graphical representation of the set of radiuses versus the set of orientations. The method more over includes calculating the process center by applying a curve-fitting equation to the off-centered plot.

摘要:
A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.

Methods and systems to perform a computer task in a reduced power consumption state, including to virtualize physical resources with respect to an operating environment and service environment, to exit the operating environment and enter the service environment, to place a first set of one or more of the physical resources in a reduced power consumption state, and to perform a task in the service environment utilizing a processor and a second set of one or more of the physical resources. A physical resource may be assigned to an operating environment upon an initialization of the operating environment, and re-assigned to the service environment to be utilized by the service environment while other physical resources are placed in a reduced power consumption state.
摘要:
A tent having two joints, multiple frames and a fly. The frames are mounted on the joints and are classified into a stationary frame, a supporting frame and at least one pivoting frame. The frames cooperate to define a parking space for receiving a cycle when unfolding. The fly covers the frames and the parking space. The frames are capable of folding and overlapping one another to facilitate carrying and storage of the tent.
