Silicon Wafer Temperature Distribution, Daniel Gonzalez, Nathan Jones, Dylan Justice Nov 2012

Silicon Wafer Temperature Distribution, Daniel Gonzalez, Nathan Jones, Dylan Justice

Mechanical Engineering

Applied Materials is a global company that designs equipment for use in the semiconductor manufacturing industry. The scope of this project covers process chambers used for depositing thin chemical films onto silicon wafers. These processes must take place in particularly specific environments– including extremely low pressures and high temperatures. One challenge engineers face when designing these processes is carefully controlling the thermal behavior of silicon wafers. Typically, behavior is predicted using time consuming and computationally expensive CFD simulations. We have been asked to address this issue with a simpler, faster model which will allow engineers to reduce the total number …

Cryogenic Heat Switch, Daniel Brodkey, Esteban Ruiz, Cristal Vasquez Jun 2012

Cryogenic Heat Switch, Daniel Brodkey, Esteban Ruiz, Cristal Vasquez

Mechanical Engineering

A prototype cryogenic heat switch capable of transferring heat at cryogenic temperatures, while decoupling to prevent irreversible heat damage and minimizing parasitic heat loads, is to be developed for the Jet Propulsion Laboratory. Various material properties and cryogenic heat transfer processes will be investigated to determine the best solution for this project. A working proof of concept model will be constructed that may eventually be integrated onto a spacecraft’s passive cooler systems to protect them from the irradiation emitted by the sun, from the albedo of planets, and other malicious heat sources.


California Olive Ranch Hedger, Tyler Enos, Seth Abbott, David Gamba Jun 2012

California Olive Ranch Hedger, Tyler Enos, Seth Abbott, David Gamba

Mechanical Engineering

The purpose of this project is to evaluate the problems of the current KCI (Kingsburg Cultivator Incorporated) olive tree hedger in use at California Olive Ranch (COR) in Artois, CA, and then correct these problems which should yield a better performing, more efficient, and reliable machine. These problems include: the hydraulic oil temperature getting too high, the saw blades not having enough horsepower, and poor cutting performance due to operator error as well as terrain variations.
