Abstract:

Various embodiments for providing enhanced power savings in mobile computing devices are described. In one or more embodiments, a mobile computing device may monitor the battery power level remaining.

International Classification:

H01J 37/32
C23C 16/50
C23C 16/458
C23C 16/52

Abstract:

The present disclosure relates to methods and systems for chucking in substrate processing chambers. In one implementation, a method of chucking one or more substrates in a substrate processing chamber includes applying a chucking voltage to a pedestal. A substrate is disposed on a support surface of the pedestal. The method also includes ramping the chucking voltage from the applied voltage, detecting an impedance shift while ramping the chucking voltage, determining a corresponding chucking voltage at which the impedance shift occurs, and determining a refined chucking voltage based on the impedance shift and the corresponding chucking voltage.

International Classification:

H01J 37/32

Abstract:

Embodiments of the present disclosure generally relate to apparatuses for reducing particle contamination on substrates in a plasma processing chamber. In one or more embodiments, an edge ring is provided and includes a top surface, a bottom surface opposite the top surface and extending radially outward, an outer vertical wall extending between and connected to the top surface and the bottom surface, an inner vertical wall opposite the outer vertical wall, an inner lip extending radially inward from the inner vertical wall, and an inner step disposed between and connected to the inner wall and the bottom surface. During processing, the edge ring shifts the high plasma density zone away from the edge area of the substrate to avoid depositing particles on the substrate when the plasma is de-energized.

International Classification:

H01J 37/32

Abstract:

A method and apparatus for operating a plasma processing chamber includes performing a plasma process at a process pressure and a pressure power to generate a plasma. A first ramping-down stage starts in which the process power and the process pressure are ramped down substantially simultaneously to an intermediate power level and an intermediate pressure level, respectively. The intermediate power level and intermediate pressure level are preselected so as to raise a plasma sheath boundary above a threshold height from a surface of a substrate. A purge gas is flowed from a showerhead assembly at a sufficiently high rate to sweep away contaminant particles trapped in the plasma such that one or more contaminant particles move outwardly of an edge of the substrate. A second ramping-down stage starts where the intermediate power level and the intermediate pressure level decline to a zero level and a base pressure, respectively.

Abstract:

The present disclosure provides a detailed description of techniques used in systems, methods, and in computer program products for bi-directional social media broker services that connect multiple social media sites using a common management framework. The claimed embodiments address the problem of efficiently scaling and managing bidirectional interaction with multiple social media publishing channels. More specifically, the claimed embodiments are directed to approaches for a computing platform having multiple message broker modules that enable bi-directional communication of messages between a common resource manager and a plurality of social media sites. The message broker modules can receive messages in a unified message format from the common resource manager, queue the messages for asynchronous processing, translate the messages from the unified message format to a site-specific format, and deliver the translated messages to multiple social media sites.
