The NEMS and MEMS Proto Fab (NMPF) situated in the IIT Bombay campus in Powai, Mumbai, is a unique, highly specialized fabrication unit for NEMS/MEMS and microfluidic device research and prototyping needs. The facility offering unparalleled flexibility to entities that require prototyping fabrication services, unlike other large scale foundries or research (academic) fabs. Established through support by the Ministry of Electronics and Information Technology (MeitY), Government of India, this is one-of-its-kind facility, with the idea of catalyzing the MEMS, microfluidic and sensors industry in India, in line with the Make in India initiative.

Our mission is to provide a sandbox for labs, startups and SMEs so that they don’t have to look overseas for upgrading their proof-of-concept devices to a demonstration prototype. Our vision is to foster ecosystem development for micro- and nano-technology backed sensors and device development in India.

NMPF is equipped with state-of-art microfabrication equipment and trained personnel. We have access controlled clean-rooms enabling microfabrication processes in a controlled environment, resulting in excellent reproducibility and higher yields.

The location of the facility offers a dual accessibility advantage of a well connected location, and approach to the world-class facilities already existing inside IIT Bombay. For start-up companies looking to engage IIT Bombay for consultancy in the areas of MEMS, microfabricated sensors, microfluidics etc., NMPF offers a unique add-on benefit. Now, startups or SMEs can approach IIT Bombay with a problem and walk away with an end-to-end solution and fully functional prototypes at affordable rates.

At HPC labs, we aim to research to address future needs of high-end parallel computing. Rapid advancements in VLSI technology have ushered a new era in system design, by integrating many systems in a single framework. This makes the whole system much more powerful than it used to be earlier. It has, in turn, enabled us to solve even those problems which hardly had practical significance in the past. Our vision is to develop such high-performance, practical solutions, and contribute to the needs of both scientific and engineering community.
