• Most noteworthy achievement: I upgraded/retrofitted the existing PV cell stringer to attain 4X the throughput at 1/10th the energy cost. This involved a thermally isolating vacuum chuck and a multi-zone radiative heater at 400oC.• 3 Pending Patents: (1) apparatus for curing conductive paste, (2) system and method for annealing PV cells, (3) magnetic wafer gripper for CVD system• Tools worked on: CVD, next gen CVD, next gen RPD (type of PVD), PV cell stringer (SCB), next gen SCB, TRIEX module• Projects: reverse-engineered RPD electromagnetic & thermal physics, next gen tool designs for RPD & CVD & SCB, in-situ spectrometer for wet tools, robot end effectors, batch wafer CVD process carriers, list of more than 15 CIP projects

• Most noteworthy achievement: I created a showerhead that achieves better than 0.25% NU (neglecting edge effects) for even the shortest cycle ALD processes on the order of 50ms. In addition, the 1X cost was only 50% more expensive than the production volume cost of a regular showerhead.• 3 Patents: (1) liquid precursor vaporizer 20150377481, (2) heated filter for process gas delivery 20160102398, (3) modular vaporizer 20160222508• 2 Pending Patents: (1) ALD showerhead (2) universal gas delivery system• Tools worked on: Flowable Oxide, TELOS, SPEED, ALD (Vector platform)• Projects: showerheads, custom universal gas delivery substrate system, gasbox, chamber disconnects, remote plasma clean, degassers, vaporizers, filters, cooling & heating systems

• Most noteworthy achievement: I created a tool that can produce sub-micron flatness in glass wafers. This is achieved in 30 min vs 3 days via the established method. It was also the 1st success in the project’s history of 15 yrs.• Developed new technology for optical sensing & non-contact motion actuation (via fluid shear force) in furnace at 600oC• 5 sequential prototypes for non-contact wafer molding at 600oC• KC for grating patterner; design and structural, thermal, & vibration FEA• Publications list @ esung.weebly.com
