1. Overview: Eastern India’s Emerging Semiconductor Corridor

While western and southern states have historically hosted software services, West Bengal is rapidly distinguishing itself as a pioneer in hardware sovereignty, cleanroom wafer fabrication, and specialized microelectronics.

Backed by institutions like IIT Kharagpur, IIEST Shibpur, Jadavpur University, and Calcutta University—which produce thousands of India’s top VLSI, materials science, and physics post-graduates each year—Kolkata offers an unmatched talent pipeline for pure-play semiconductor manufacturing.

The Government of West Bengal, via the West Bengal Industrial Development Corporation (WBIDC) and the state's dedicated Electronics & IT Department, has actively allotted industrial land parcels at Vidyasagar Industrial Park (Haringhata) and Salt Lake Sector V to anchor mega-scale semiconductor fabrication parks.
