IISc to Empower Tribal Students as Future Semiconductor Leaders

Image
 Bridging the Gap: Empowering Tribal Students in Semiconductor Technology The semiconductor industry, essential for powering modern technologies like smartphones and satellites, remains largely inaccessible to marginalized communities in India. Despite a strong engineering talent pool, representation from Scheduled Castes (SC) and Scheduled Tribes (ST) in semiconductor fields is minimal, with reserved seats often going unfilled. To address this gap, the Ministry of Tribal Affairs (MoTA) and the Indian Institute of Science (IISc), Bengaluru, have launched a fully sponsored semiconductor training programme for tribal students from rural areas. Hosted at IISc’s Centre for Nano Science and Engineering (CeNSE), the initiative aims to equip students with industry-relevant skills and open doors to high-tech careers. A Tiered Learning Approach The programme is divided into three modules: Exposure Module (2–3 weeks): Introductory overview of semiconductor tech. Foundation Module (60 days): ...
