- Asserted semiconductor customers by calibrating and testing every system and submodules in a TWINSCAN NXT machine for a successful exposure of wafers according to recipe specifications.- Systems Integration Engineer SIE for new installations and relocations of DUV scanner machines ranging from XTs, to the newest NXTs.- Within the correct calibrations a NXT scanner exposes DUV light in silicone wafers to reach nanometer precision on layer overlay. The scanner is also optimized for a high throughput of wafers per hour WPD.

Santa Barbara, California Area

• Researched extensively topics including heat transfer, semiconductor thermal behavior at heavy heat loads, radiation, solar emission spectrum, between other thermodynamic topics.• Designed a 295-component assembly in Solidworks of a solar simulator that tests the thermal resilience of SONOS outdoor product line.• Created full detail drawing packet with GD&T and assembly instructions.• Utilized FEA skills and knowledge in COMSOL and Solidworks, to simulate and analyze Heat Transfer and Solid Mechanics failure models and come up with an optimized design.• Solar Gain Simulator Rig mimics the varying irradiance from the sun reaching at any location in Earth while simulating the sun elevation and azimuth angles throughout a selected date, by moving a heat source in a hemisphere path.

Santa Barbara, California Area

• Estimated thermal properties of thin-film nano-scale GaAs semiconductor devices utilizing a mature laser-based technique called Transient Thermal Grating (TTG).• Collected and analyzed data in Matlab for epitaxial GaAs semiconductor wafers growth in silicon and phosphate substrates.• Determined thermal diffusivity and concluded efficiency between samples for applications in the optoelectronics field, where transistors of this compound have shown to be faster than silicon and are getting smaller and more efficient every year (Moore’s Law).• Presented research in the engineering symposium for the 2019 SHPE National Convention.

El Paso, Texas Area

• Teamed up with Ph.D. candidates and achieved solutions for energy efficiency of vineyards while also providing research initiatives for water loss minimization. • Collected data and proposed active solutions for:1. Reducing the carbon footprint by 31%, by implementing a low weight glass bottle.2. Slashing bottle packaging costs with the implementation of the new bottle, for savings of $227,000 a year in a zone with huge local economic impact and where 90% of Mexico’s wine is produced.
