EXPERIENCE

Semiconductor Fabrication Engineer at Wolfspeed, A Cree Company January 2015 – February 2016

• Improved plasma ash processes and solvent strip processes for yield gains • Implemented a heuristic system to detect and shutdown “rogue” manufacturing • Led factory automation efforts between automation and process engineer teams

• Identified capital requirement for future growth, identified equipment suppliers, assisted with pricing negotiations and agreements, established acceptance criteria, performed source inspections, outlined instillation, startup, and process qualification plans with facilities teams and product teams. Process Engineer at Texas Instruments

June 2012 - January 2015

Yield Enhancement experience: • Monitored and ensured transistor/gate process defectivity through statistical process control methods, large scale data analysis and team brain storming sessions • Characterized failure inducing defects versus nuisance cosmetic defects by establishing a “big data” analysis method. • Assisted with identifying root cause and resolving large impact defectivity issues using graphical & quantitative data analysis methods • Assisted with customer returned die failure analysis to determine root cause of fails by analyzing die de-processing data, layout data, and analyzing electrical circuit schematic data • Worked with teams to design experiments to determine root cause, drive to resolution, and measure effectiveness • Analyzed and compiled high level data for transistor/gate manufacturing loop to present to fabrication plant management • Implemented new defect inspection strategy in the transistor/gate loop for better excursion control and baseline defect reduction Process engineering experience: • Collected data and performed analysis to support a lower cost, robust, process qualification for nonmetal RTP processes using silicon oxides instead of doped silicon. • Implemented tool interdiction systems, which involved acquiring critical signals from the tool coupled with statistical analysis techniques. • Identified and eliminated gaps in process steps and procedures that could potentially lead to major yield loss by working with factory automation group to install controls. • Worked with team to implement a system that helped with decreasing time to root cause determination for day-to-day qualification fails Undergraduate Researcher in Dielectric Materials at University of Florida September 2008 - May 2012

Researched the electronic properties of piezoelectric, ferroelectric, and dielectric materials. Investigation was mainly focused on the relationship between material polarizability and atomic arrangements (crystallography). EDUCATION

University of Florida

Bachelor’s Degree, Materials Science & Engineering, 2008 – 2012, Specialization: Electronics VOLUNTEERING

Fundraising Campaign Lead at Texas Instruments' DMOS5 Fab at JDRF International 2014 - Present (1 year)

• Co-lead the fundraising efforts for JDRF at Texas Instruments • Helped brainstorm fundraising events such as: Coffee Shop, Unused Items Auction, and Coin Wars between departments Mentor at Visioneering at Southern Methodist University's Lyle School of Engineering Led a team of middle school students to first place in Visioneering competition by mentoring on: What engineering is and how it solves problems and how to work as a team to synthesize a solution to a real world problem.
