US Patent:

62689169, Jul 31, 2001

Filed:

May 11, 1999

Appl. No.:

9/310017

Inventors:

Shing Lee - Fremont CA
Mehrdad Nikoonahad - Menlo Park CA
Xing Chen - San Jose CA

Assignee:

Kla-Tencor Corporation - San Jose CA

International Classification:

G01J 400
G01N 2100

US Classification:

356369

Abstract:

The surface of a doped semiconductor wafer is heated locally by means of a pump beam whose intensity is modulated at a first frequency. The heated area is sampled by a probe beam whose intensity is modulated at a second frequency. After the probe beam has been modulated (reflected or transmitted) at the first frequency by the wafer, the modulated probe beam is detected at a frequency equal to the difference between the harmonics of the first and second frequencies to determine dose of the dopants in the wafer. Such or similar type of instrument for measuring dose may be combined with an ellipsometer, reflectometer or polarimeter for measuring dose as well as thickness(es) and/or indices of refraction in a combined instrument for measuring the same sample.

US Classification:

2041923

Abstract:

The present invention provides a method and apparatus for preferential PVD conductor fill in an integrated circuit structure. The present invention utilizes a high density plasma for sputter deposition of a conductive layer on a patterned substrate, and a pulsed DC power source capacitively coupled to the substrate to generate an ion current at the surface of the substrate. The ion current prevents sticking of the deposited material to the field areas of the patterned substrate, or etches deposited material from the field areas to eliminate crowning or cusping problems associated with deposition of a conductive material in a trench, hole or via formed on the substrate.

International Classification:

H04N 19/105
H04N 19/196
H04N 19/51
H04N 19/172

Abstract:

A disclosed computer-implemented method may include (1) selecting, from a video stream, a reference frame and a current frame, (2) collecting a reference histogram of the reference frame and a current histogram of the current frame, and (3) generating a smoothed reference histogram by applying a smoothing function to at least a portion of the reference histogram. In some examples, the computer-implemented method may also include (1) determining a similarity metric between the smoothed reference histogram and the current histogram and, (2) when the similarity metric is greater than a threshold value, applying weighted prediction during a motion estimation portion of an encoding of the video stream. Various other methods, systems, and computer-readable media are also disclosed.

Abstract:

A computer-implemented method executed by one or more processors includes receiving interconnection data for a proposed interconnection to a power grid; accessing a power grid model including a topological representation of the power grid, electrical specifications of grid components, and empirical operation characteristics; and generating, using the interconnection data for the proposed interconnection to the power grid, and the power grid model, simulated power grid data. The simulated power grid data is based on simulating operation of the power grid with the proposed interconnection coupled to a location of the power grid identified by the interconnection data during a simulated time period. The simulated power grid data includes a plurality of different temporal and spatially dependent characteristics of the power grid. The method includes evaluating, using one or more metrics, the simulated power grid data; and outputting evaluation results of the one or more metrics.

International Classification:

H04W 36/06

Abstract:

Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract:

Systems and methods for controlling commits to a search platform in a content management system. Identification information of endpoints may be passed down from endpoints to the search platform. Endpoints may be grouped based on their identification information, and commit policies may be assigned to each group of endpoints. A commit request from an endpoint to the search platform may be intercepted, its group may be determined based on the endpoint identification information, and commit policy for that group may be applied to the commit request.
