46:47 - HackerFab's Role in India's Semiconductor Mission HackerFab IITB is India’s first semiconductor fab built and run by students, and the most DIY semiconductor fab in India. Unlike Indian semiconductor companies, HackerFab IITB relies on grants and donations instead of revenue. The HackerFab IITB was co-founded by Aryamman Bhatia, Abhineet Agarwal, and Kartik U Chikkanagoudar. During Runtime's visit to HackerFab IITB, core members Devavrat Patni and Jai Bellare also showed Caleb Friesen around. The three main systems that have been built out at the HackerFab at IIT Bombay are: 1. A DLP-based maskless lithography machine that patterns at resolutions of 10um. 2. A quartz-based tube furnace that is capable of reaching 1,200 °C and is built for oxidation as well as a blueprint for future CVD systems. 3. A DC plasma sputter that uses argon for film deposition. This uses a magnetron system for directing particles and a turbomolecular pump to reach up to 1e-5 mbar. The DC plasma sputter also has a quartz-crystal monitor built to measure the deposition rate. HackerFab IITB is a team of 15 students. During our RuntimeBRT visit, Caleb Friesen got to meet three of those team members: Aryamman Bhatia, Devavrat Patni, and Jai Bellare. Their goal is to make fabrication tools accessible for training and prototyping, helping students to gain real hands-on experience. HackerFab IITB's long-term vision is to complete a toolset to fab 2 um pitch transistors by the end of 2026, build "fab in a box" cleanroom-free fabrication systems for colleges, develop EDA software for their in-house process flow, train more than 100 students in two years and assist courses at IIT Bombay. Their future projects include: RF plasma sputtering, atomic layer deposition, an ion implantation system, an automated probe-station, a thermal evaporator, and a spin-on dopant system. HackerFab IITB is supported by SemiX which is the IIT Bombay Center for Semiconductor Technologies, Emergent Ventures, CG Semi, and gradCapital.
