▪ Grew HgCdTe layers (II-VI) through liquid phase epitaxy (LPE) across a broad range of wavelengths and thicknesses. Utilized process modeling to increase production yield significantly. ▪ Maintained several LPE systems and instrumentation, performing both diagnostic repairs and routine upkeep and replacements. ▪ Developed campaign summaries for LPE and MBE programs to determine and summarize process capabilities. Identified critical specification limits by looking at downstream yields. ▪ Conducted Hall tests for IR Materials department.

 Developed grind/CMP lapping routines to planarize silicon, oxides, nickel, iron and copper surfaces. Wrote and implemented dicing routines using CNC and windows software. Ensured several MEMS products remained within control limits during photolithography, plating, sputter, LPCVD/PECVD, wet etch and milling operations.

-Prepared gallium nitride seeds for growth to produce wafers used in LEDs. Ran diagnostics on pre and post growth crystals for process development.

Examined the lubricating properties of polymers and analyzed the structure present in gecko feet to develop materials with similar adhesive forces.
