What is a semiconductor?
- A semiconductor is any material that has an electrical conductivity between a conductor (such as copper) and an insulator (such as rubber or glass).
- The conductivity of a semiconductor can be controlled and modified by introducing impurities or defects into the crystal structure of the material.
- Concern: Many toxic materials, such as arsenic, antimony, and phosphorus, are used in the fabrication process.
Applications of semiconductors in daily life
- Diodes allow current to flow in only one direction, commonly used in power supplies and lighting applications.
- Transistors act as switches or amplifiers and are a fundamental building block of digital electronics.
- Microprocessors are ICs, the brain of many electronic devices (computers, smartphones).
- Solar cells are made of semiconductor materials like silicon.
- Led lights are semiconductor devices.
India Semiconductor Mission(ISM)
- Launched in 2021 with Rs 76,000 crore funding under the Ministry of Electronics and IT (MeitY).
- Aims to provide financial support to companies investing in semiconductors, display manufacturing, and design ecosystems.
- ISM will serve as the nodal agency for efficient implementation of schemes.
Components of ISM
- Scheme for setting up of Semiconductor Fabs in India: Provides fiscal support to attract investments for semiconductor wafer fabrication facilities.
- Scheme for setting up of Display Fabs in India: Provides fiscal support to attract investments for TFT LCD / AMOLED-based display fabrication facilities.
- Scheme for setting up of Compound Semiconductors / Silicon Photonics / Sensors Fab and Semiconductor Assembly, Testing, Marking and Packaging (ATMP) / OSAT facilities in India: Provides fiscal support of 30% of the Capital Expenditure to the eligible applicants.
- Design Linked Incentive Scheme.
Global Scenario
India’s History
- Despite a promising start, India lost out in the semiconductor revolution of the 1980s, while countries like China and Taiwan raced ahead.
- A 100% central government-owned enterprise, Semiconductor Complex Limited (SCL), was set up in the early 1980s with a manufacturing facility in Mohali in Punjab.
- India’s dream of becoming a semiconductor manufacturing hub was shattered by a mysterious fire that broke out at the Mohali facility in February 1989.
- In 2006, SCL was restructured as a research & development centre within the Department of Space. It was renamed ‘Semiconductor Lab’.
Current status
- Despite being the global leader in semiconductor chip design, India imports 100% of its semiconductors.
- The current demand for semiconductors in India is around $24 billion, which is met through imports from countries like China, Singapore, Hong Kong, Japan, and the United States.
- There is not a single Indian company involved in the fabrication of semiconductor chips.
Progress in semiconductor manufacturing
- In September 2022, Vedanta and Foxconn announced a Rs 1.54 lakh crore investment for semiconductor and display plants in Gujarat.
- The international consortium (ISMC) (a joint venture between Abu Dhabi-based Next Orbit Ventures and Israel’s Tower Semiconductor) has proposed a $3 billion investment for a chip-making plant in Karnataka.
- Micron Technology has announced an $825 million investment for a new assembly and test facility in Gujarat.
- Almost all the top international chip design companies have a presence in India.
- Today, India has the distinction of designing over 2,000 chips every year.
What is ailing India’s Semiconductor Industry?
- Semiconductor manufacturing is difficult and expensive. It requires billions of dollars of investment, top-quality raw materials, and reliable infrastructure.
- Shortage of raw materials: Apart from Silicon and metals, germanium and gallium arsenide are rarely found in India.
- High maintenance: These plants demand a consistent supply of water, electricity, and protection from the elements.
- Semiconductor manufacturing requires a high-skilled STEM labour force. The universities in India currently don’t have state-of-the-art infrastructure labs to do research, which is limiting a lot of students from entering this sector.
Initiatives in India
- Production-Linked Incentive (PLI) Scheme.
- Design-Led Incubation (DLI) Scheme.
- Digital RISC-V (DIR-V) Program.
- India Semiconductor Mission.
- Semicon India program.
- Scheme for Promotion of Manufacturing of Electronic Components and Semiconductors (SPECS).
Way Forward
- India must collaborate with international partners. The chip manufacturing and design supply chain is complex and requires specialisation, materials, and talent that no single country can provide.
- India needs to prioritise ease of doing business alongside offering incentives to foster the growth of semiconductor manufacturing.
- India should provide long-term stability of policy so that the company can be assured about its return on investment.
