• TCO (Transparent Conductive Oxide) Process Engineer

  • May 2016 - Dec 2016

  • Led the development and process improvement of Transparent Conductive Oxides (TCO) for future production processes in Photo-Voltaic (PV) solar cells. • Maintained responsibility for the production deposition processes of TCO layers, intrinsic zinc oxide (i-ZnO) and tin doped indium oxide(ITO). • Controlled film thickness, electrical resistance and conductance and PV parameters including transmission, reflectance and absorption. • Served as a key individual on a cross-functional process team, improving device efficiencies including the main p-n junction processes and monolithic integration process (laser scribing). • Managed a number of development projects maintaining compliance with strict manufacturing processing standards and ISO requirements. • Played a key role in the preparation of process documentation to obtain initial ISO certification.

• Vacuum Process Engineer

  • 2006 - 2016

  • Led the successful development of Giant Magneto Resistive (GMR) “spin valves” and “synthetic anti-ferromagnets” for future production processes. • Directed the production deposition processes for GMR sensor layers including control film thickness, electrical resistance and magnetic parameters and the development a high moment (CoFe) seedlayer for electro-plating. • Controlled film thickness to less than 0.1 nm and magnetic parameters including freelayer exchange coupling, dR/Rmin, Freelayer Coercivity, anisotropy, magneto-striction and electrical resistance. • Maintained responsibility for the deposition and etch processes of Thin Film Seedlayers including precursor sputter deposition processes necessary for electro-plating and alumina deposition processes. • Served on the New Technology Integration Teams, providing comprehensive engineering line support to a “non-regular hours” manufacturing shift. • Managed statistical data analysis projects to successful completion, delivering reports on internal calibration, statistical process control and critical-to-function capability (Cpk) reporting. • Performed Measurement Systems analysis for all production measurement systems including resistance probers, magnetic hysteresis, magneto-striction, optical, cantilever profilometer and X-ray fluorescence. • Conducted detailed data analysis through the use of different statistical software packages and open source R (R-project.)
