Post Doctoral Fellows

Alumni
	Y. Nagendra Prasad completed his Ph.D. in 2008. He has studied the mechanism of high selectivity STI slurries and proposed a new alkaline slurry and an inhibitor for copper CMP. The alkaline slurry is based on arginine and hydrogen peroxide. Eventhough it is alkaline, it does not polish silicon dioxide and hence will not cause oxide erosion. Uric acid is used as inhibitor and it is much more benign compared to the commonly used BTA. Nagendraprasad worked as a faculty in NIT Trichy, India and then as a post doctoral researcher with Prof. Jin Goo Park, Hanyang University, Korea. Then he worked as Assistant Manager in KC Tech, Korea; next as Manager, R&D in MCK, Korea and as Research Assistant Professor, in Hanyang University, Korea. At present he is the Director (R&D),Advanced NanoSurface Technologies (Shenzhen) Co. Ltd., China.
	R. Prasanna Venkatesh: Prasanna completed his PhD in 2010. His project was on understanding copper dissolution in aqueous solutions using electrochemical impedance spectroscopy.

He briefly worked in the company MCK, Korea and is currently Associate Professor in the Department of Chemical Engineering, IIT-Guwahati
	R. Manivannan : Manivannan completed his Ph.D. in 2010. His project was on understanding the behavior of high selectivity slurries. He determined that the abrasives play a key role in determining the selectivity of the slurry. Ceria particles are widely used in STI slurries. He has also obtained interesting results which may help in determining the 'active sites' on ceria which chemically interact with the silica surface. This is sometimes referred to as 'chemical tooth'. He also showed that, at least in some conditions, the silicon nitride polish does NOT occur by the familiar 'two step mechanism' where the nitride is first converted to oxide, and then the oxide is removed by CMP. He was a post doctoral researcher in Prof. Yuzhuo Li's group in Clarkson University, USA for an year and he worked as post doc with Prof. Jin Goo Park, Hanyang University,Korea. Now, he is an Associate Professor in Dept. Chem. Engg. NIT-Raipur
	S. Noyel Victoria: Noyel Victoria completed her Ph.D. in 2011. Her work focussed on understanding the mechanism of Cu, Ru and Ta CMP using labs scale polisher and electrochemical analysis.

	B.V.S. Praveen: Praveen completed his Ph.D. in 2015. He synthesized ceria abrasives by different methods and employed them for STI CMP. He studied the interaction between abrasives and additives in high selectivity STI CMP and has done extensive characterization of ceria abrasives obtained from various sources to identify what causes some abrasives to yield high selectivity and other abrasives to yield low selectivity. He identified the presence of La as the critical factor. He also synthesized ceria with controlled La doping and determined which amino acids are sensitive to La doping (i.e. which will yield low selectivity). He was working as Assistant Professor in Dept. Chem. Engg. in NIT Warangal and then in BVRIT, Hyderabad. Currently, he is working as a faculty in CBIT, Hyderabad.
