University of Illinois at Urbana Champaign, ECE Post-doctoral Research Associate (June 2000-June 2002)

• Developing a dry-etching process for the fabrication of InP photodiodes.

• Developed an inductively coupled plasma-reactive ion etching (ICP-RIE) process to etch highly anisotropic nanostructures for waveguides in InP and InGaAsP alloys with smooth sidewalls and low loss.
• Developed an electron-beam lithography process for the realization of nanostructure devices such as ring resonators for a Leica 10.5 EBMF and a JEOL 6000FS lithography tool.
• Demonstrated racetrack resonators in conjunction with the Sarnoff Corporation (Princeton, NJ)

• Developing a process for etching backside via holes of varying profiles through InP substrates

• Adesida research group manager for InP and metamorphic p-i-n photodiode efforts
• Wrote proposals to NSF, DARPA, ONR, and SRC
• Pioneered the use of the newly delivered JEOL 6000FS E-beam at UIUC; Developed standards for operation and adapted Leica-based designs to the new JEOL instrument
• Co-writing a CAD-based software package to facilitate development of e-beam lithography jobs as well as proximity correction on a low-cost PC platform; Software is intended for commercial distribution.
• Trained users on the JEOL 6000FS E-Beam and Unaxis (PlasmaTherm) SLR 770 ICP-RIE.
• Coordinating the development of the web page for the Adesida research group at UIUC.

University of Delaware, ECE Graduate Student Research Assistant (January 1995 – May 2000)

• Co-designed, built and tested the first Si-based Resonant Interband Tunneling Diode (RITD) operating at room temperature in a collaborative project with the U. S. Naval Research Laboratory (Washington, D.C.) and Raytheon Systems Co. (Dallas, TX). Patent pending as co-inventor.
• Optimized anneal conditions to obtain the best RITD performance.
• Developed designs spanning four orders of magnitude in current density: high current density (>22 kA/cm²) for high speed logic and low current density (<10 A/cm²) for low power memory applications.
• Performed a series of low temperature measurements (4.2 K) to elucidate the role of phonons in the current transport of Si and SiGe RITDs.

• Investigated methods of improving photoresponsivity and bandwidth of III-V MSM photodiodes
• Developed an RC time constant small signal equivalent circuit model of an MSM photodiode
• Implemented a VCSEL/MSM/DOE static-RAM circuit (collaborative project with Prof. Dennis Prather, Univ. of Del.)

• Co-developed low resistance ohmic contact technologies for Group IV alloys which meet industry standards.

• Responsible for pioneering the use of Cadence software at the University of Delaware. Introduced the package to faculty and students through training via ELEG 650 (Semiconductor Design and Fabrication)
• Developed a tutorial web page explaining how to use the design features of the Virtuoso cell layout editor (http://www.ece.udel.edu/~eemadlab/cadence/index.html).

• George Laird Fellowship (1997)
• IEEE Outstanding Leadership and Service Award (1996)
• Department Chair Award (1996)
• IEEE Delaware Bay Section Student Activities Award (1995)
