PROFESSIONAL PROFILE
Research Scientist, University of Texas at Dallas 03/2009 – 02/2012
Developed high performance sub-5 nm “top-down” silicon NW transistors, which have high peak hole mobility, current density and drive current as well as low drain leakage current due to significant positive quantum confinement and well organized fabrication process.This study can deliver high performance for potential impact on both CMOS scaling andemerging applications such as bio-sensing. The results were published in Nano Letters,March and November 2011.
Fabricated the world smallest SiGe NWs (4 10 nm) applicable to photonic sensor by using electron beam lithography (EBL) with hydrogen silses quioxane (HSQ) resist and
inductively coupled plasma (ICP) etching.
Researched on direct wafer bonding of GaN on sapphire and Si wafer for the application of High Electron Mobility Transistor (HEMT) devices or light emitting diode (LED) or solar cell in case of special purpose.
Team Leader & FA Engineer, LG Siltron, Korea 09/ 2005 – 01/2009
Developed high quality 300 mm silicon on insulator (SOI) wafers for the application of CPU of game console such as PlayStation 3, XBOX and Nintendo Wii. This research work was nominated for 2007 LG Grand Research & Development Award in LG group that
consists of 53 branch companies (estimated value was $ 10 million).
Developed the world highest quality 200 mm strained-SOI (SSOI) wafers with tensile strain that can offer higher performance than that of SOI, being able to replace the Si channel for high speed CMOS application(estimated value was $ 5million).
Served as a failure analysis (FA) engineer for technical customer service in Si wafer business. Physical and chemical analysis was used to verify customer’s complaints and solved many issues raised by main customers such as Samsung, hynix, TI, SAS, Soitec,TSMC, SMT, NEC, etc.
Received a LG first prize at LG Academy and earned 93 point that has been a record of LG whole group since the course started.
Research Associate, Imperial College London, U.K. 10/2002 – 07/2004
Performed an Engineering and Physical Sciences Research Council (EPSRC) project titled "SiGe HMOS micro-power phase". Mainly fabricated HMOS transistors in cleanroom and measured electrical properties of the quantum well transistors.
Developed a novel SiGe on insulator (SGOI) formed by Ge implantation into SOI and
subsequent O2gas annealing. This is the world first success of high quality SiGe synthesisby ion-implantation.
Researcher, Korea Testing Laboratory, Korea 07/1995 – 07/1999
Tested electrical & lighting appliance and their components for safety, quality and energy efficiency by National regulations and International standards. Served as a member of Korean Standards (KS) council designated by Korean government for making or revising KS.
Served as an assistant secretary in IEC System for Conformity testing and Certification of Electrotechnical Equipment and Components (IECEE) Council of republic of Korea. The Scheme was based on the principle of mutual recognition (reciprocal acceptance) by its members of test results for obtaining certification or approval at national level.
