India's First Advanced 3D Chip Packaging Unit

India is setting up its first advanced 3D chip packaging unit in Bhubaneswar, a groundbreaking project under the Rs 76,000 crore India Semiconductor Mission (ISM). The unit, expected to significantly advance India's semiconductor capabilities, is being closely monitored by the government.

Project Overview

  • The project has a budget of Rs 1,934 crore and is led by US-based 3D Glass Solutions.
  • It focuses on producing glass substrate panels and advanced 3D heterogeneous integration (3DHI) modules.
  • The applications of this technology include artificial intelligence, 5G, defence, and data centers.
  • Investors include Intel, Lockheed Martin, and various venture capital and private equity funds.

Significance and Technological Innovation

  • This project is part of ten plants approved under the ISM, including a chip fabrication plant by the Tata Group.
  • It utilizes glass-based substrates and 3D stacking technologies offering higher precision and thermal stability than traditional silicon-based methods.
  • The project's technology aims to address the challenges posed by Moore’s Law by enhancing computing power through vertical stacking.

Economic and Employment Impact

  • The facility is anticipated to produce 70,000 glass panels and 50 million assembled units annually.
  • It is expected to generate approximately 2,500 direct and indirect jobs.

India Semiconductor Mission (ISM)

  • Launched in 2021 with a Rs 76,000-crore outlay to develop a comprehensive chip ecosystem.
  • Ten semiconductor projects have been approved across six states, with investments over Rs 1.6 lakh crore.
  • The government may introduce ISM 2.0, focusing more on supporting ancillary industries and design-side incentives.

Chip fabrication plant

A manufacturing facility dedicated to producing semiconductor chips from raw materials, involving complex processes like photolithography, etching, and doping to create integrated circuits on silicon wafers.

Moore's Law

An observation that the number of transistors on integrated circuits doubles approximately every two years, leading to increased computing power and decreased costs. Advanced packaging technologies like 3DHI aim to overcome the physical limitations of this trend by improving performance through vertical stacking.

Glass substrate

A thin sheet of glass used as a base material in semiconductor manufacturing, offering potential advantages in precision, thermal stability, and cost-effectiveness over traditional silicon substrates for advanced packaging technologies.
