Abstract:
An apparatus for treating the surfaces of containers includes a chamber for holding a container and provides precursor materials via an annulus formed by coaxially arranged electrodes at which plasma is created upon application of voltage and the container is treated.
Abstract:
Techniques for monitoring neurophysiologic indicators of the members of a team while performing one or more collaborative tasks, for analyzing the collected neurophysiologic data and environmental data, for generating feedback, and for generating assessments of the performance of the team based on the collected data are provided. Feedback can be created based on the assessments of the team performance. Assessments of team performance can be performed in real time and feedback can also be provided in real time. In other embodiments, feedback can be provided to team members and/or the team as a whole after training exercise and/or simulation has been completed.
Abstract:
Embodiments of the present invention generally relate to methods and apparatus for chemical vapor deposition (CVD) on a substrate, and, in particular, to a process chamber and components for use in metal organic chemical vapor deposition. The apparatus comprises a chamber body defining a process volume. A showerhead in a first plane defines a top portion of the process volume. A carrier plate extends across the process volume in a second plane forming an upper process volume between the showerhead and the susceptor plate. A transparent material in a third plane defines a bottom portion of the process volume forming a lower process volume between the carrier plate and the transparent material. A plurality of lamps forms one or more zones located below the transparent material. The apparatus provides uniform precursor flow and mixing while maintaining a uniform temperature over larger substrates thus yielding a corresponding increase in throughput.
Abstract:
Methods are disclosed of determining a fill level of a precursor in a bubbler. The bubbler is fluidicly coupled with a substrate processing chamber through a vapor-delivery system. The bubbler and vapor-delivery system are backfilled with a known dose of a backfill gas. A pressure and temperature of the backfill gas are determined, permitting a total volume for the backfill gas in the bubbler and vapor-delivery system to be determined by application of a gas law. The fill level of the precursor in the bubbler is determined as a difference between (1) a total volume of the bubbler and vapor-delivery system and (2) the determined total volume for the backfill gas.

Abstract:
A method and apparatus are provided for monitoring and controlling substrate processing parameters for a cluster tool that utilizes chemical vapor deposition and/or hydride vapor phase epitaxial (HVPE) deposition. In one embodiment, a metal organic chemical vapor deposition (MOCVD) process is used to deposit a Group Ill-nitride film on a plurality of substrates within a processing chamber. A closed-loop control system performs in-situ monitoring of the Group Ill-nitride film growth rate and adjusts film growth parameters as required to maintain a target growth rate. In another embodiment, a closed-loop control system performs in-situ monitoring of film growth parameters for multiple processing chambers for one or more film deposition systems.

Abstract:
In a computer implemented system and method for analyzing problem solving abilities, analytic models are produced to quantify how students construct, modify and retain problem solving strategies as they learn to solve science problems online. Item response theory modeling is used to provide continually refined estimates of problem solving ability as students solve a series of simulations. In parallel, student's strategies are modeled by self-organizing artificial neural network analysis, using the actions that students take during problem solving as the classifying inputs. This results in strategy maps detailing the qualitative and quantitative differences among problem solving approaches. The results are used to provide reports of strategic problem solving competency for a group of students so that teachers can modify teaching strategies to overcome noted deficiencies.
