2003
APPLIED MATERIALS, San Jose CA
2000-2003
Mechanical Engineer III GPS/Sustained Eng./Rapid Response Eng.
Provided mechanical solutions to global field problems for Rapid Thermal Processing (RTP). Worked on
creation of solutions for global problems within international and interdisciplinary teams. All of the projects
were completed under budget and under time. Examples include:
 Increased lifetime of the process parameter’s oxygen sensor on the RTP system 8 times, with an
estimated increase in revenue of $10 million.
 Resolved monthly breakages of the quartz window.
 Window breakages resolved through detailed tolerance calculations of quartz window breakages, using
stress calculations, revising the drawings and redesigning the window and it’s holder.
 Used hand calculations to disprove a FEA model that had been used in the design of the initial window.
 Created machinists blue for high temperature (up to 600C) semiconductor applications to determine the
problems of tolerance between quartz and metals.
 Redesigned a heater neck so that the heater would not break due to thermal cycling.
 Created a check valve to stop the explosion of pumps due to Silane deposits in exhaust streams.
 Created and implemented all solutions by creating ECO’s including part numbers and BOM’s.
