We have successfully set up nanofabrication and characterisation facilities in about 5000 sq. ft Class 1000 Clean room space,
including a Class 100 space for lithography, at IITM.

IIT Madras

Centre for NEMS and
Nanophotonics (CNNP)

The Centre for Nanoelectromechanical Systems (NEMS) and Nanophotonics works in close collaboration with the Departments of Biotechnology and Mechanical Engineering to carry out research and development, and is one of the most successful Interdisciplinary Research Programmes (IDRPs) by the Institute. The CNNP involves faculty members from several departments across the institute and caters to researchers from IIT Madras as well as outside.

The Centre has 5000 sq ft of Clean Room space and several sophisticated processes and characterisation equipment. Research at CNNP involves both technology and modelling, and is in the areas of silicon photonics, biosensors, RF and optical MEMS, GaN HEMT, organic electronics, diffractive optical elements, ultrasonic nanoscopy, microfluidics.

"CNNP of IITM is one of India's state-of-art facilities for the fabrication and characterization of electronic and optoelectronic devices. During my Ph.D. work, I have extensively used the CNNP facilities. This center is ideal for doing interdisciplinary research."

Dr. Gourab Datta Assistant Professor, Dept. of ECE, IIT Kharagpur

"I feel previlaged to use the state of the art CNNP facilities as part of my PhD program. I realized its relevance when I joined for my post-doc in USA where there are only few equipments that I haven't worked with in IIT Madras."

"We, at Rajalakshmi Engineering College, regularly use the services offered by CNNP for our sponsored research projects. We highly depend on the sophisticated equipment available at CNNP for our microfabrication and characterization. The lab technicians and research scholars of CNNP are very supportive during the services. The charges are nominal and it is only 50 percent for academic institutions and hence we are able to pay from projects. We also interact with Professors for technical clarifications. We thank CNNP for their dedication in their services and wish CNNP to continue and expand their services in future."

"CNNP owns a state-of-the-art fabrication facility for microelectronics and nanophotonics research. The most advanced systems such as electron-beam lithography, inductively coupled dry etching system, and high-resolution optical spectrum analyzer enables every possible research in the area of nanophotonics. Hands-on experience from the CNNP facility has been the most valuable skill set for my silicon photonics research."

"During the initial phase of my research career, where the nature of my work was quite uncertain, the CNNP project enabled me an exposure to the state of the art fabrication and characterization facilities. The CNNP project offered cleanroom fabrication facilities and protocols, quite similar to the leading fabrication facilities outside India. This also facilitated the completion of my thesis and the experience and exposure made quite a positive impact with a lot of appreciation from Prof.Uriel and the group, where I pursued my post-doctoral work. The CNNP project in my opinion is a very promising fab facility to take up advanced research work related to nano and photonics studies in India."

"I worked at the CNNP during my MS and Ph.D. and I am really happy and proud that I got this opportunity. During my Ph.D., we were the first group to design and fabricate optical Metasurfaces in India, which would not have been possible without such advanced lithography facilities that are available to us at CNNP. As someone who has worked at other world-class fabrication facilities such as MCN(Melbourne), I can proudly say that our CNNP is at par with other advanced academic fabrication facilities and improving with time."

"The facilities are providing ample scope to students to learn and do hands-on silicon fabrication technologies by staying in their own country. This is clearly advantageous in the long run as the students become at par with other international students and sometimes even outgrow them."
