Background
History & Context
What Changed
- ▶
Introduction of Commercial Compound Fabs: BEFORE, India had no commercial compound semiconductor fabrication. NOW, SiCSem (in partnership with UK's Clas-SiC Wafer Fab) is establishing India's first commercial Silicon Carbide (SiC) fab in Bhubaneswar, Odisha.
- ▶
Advanced Glass Substrate Packaging: BEFORE, approved packaging units focused on standard ATMP/OSAT processes. NOW, 3D Glass Solutions (3DGS) is setting up an embedded glass substrate unit for 3D Heterogeneous Integration (3DHI) modules in Odisha.
- ▶
Geographical Diversification: BEFORE, ISM manufacturing projects were concentrated heavily in Gujarat and Assam. NOW, the ecosystem expands significantly to Odisha (SiCSem, 3DGS), Punjab (CDIL), and Andhra Pradesh (ASIP Technologies).
- ▶
Total Approved Projects: BEFORE, the ISM had 6 active approved projects. NOW, the total count has increased to 10 projects, bringing the cumulative ecosystem investments to roughly Rs 1.60 lakh crore.
- ▶
Discrete Semiconductor Capacity: BEFORE, discrete high-power component manufacturing lacked massive scale. NOW, Continental Device India Limited (CDIL) is expanding its Mohali plant in Punjab to manufacture over 158 million high-power discrete devices annually.
What Did NOT Change
Despite this major expansion, the approved projects still do not include cutting-edge logic foundries (such as 2-nanometer or 3-nanometer node fabs), which remain concentrated in Taiwan and South Korea. The mission's primary strategy continues to focus on mature nodes, specialty compound chips, and assembly/packaging, which are structurally more feasible entry points for India's current industrial base.

Common Misconceptions
✗ India is now setting up fabrication plants for the most advanced 2-nanometer chips found in modern smartphones.
✓ The newly approved fabs and OSATs focus on mature technology nodes (28nm and above), specialty compound semiconductors (like Silicon Carbide), and advanced packaging, not cutting-edge sub-5nm logic chips.
Media headlines often use the generic term 'advanced semiconductors' to describe both cutting-edge logic nodes and advanced packaging/compound technologies, leading to public confusion about the exact type of chips being manufactured.
✗ Silicon Carbide (SiC) is just a brand name for a standard silicon chip.
✓ Silicon Carbide is a distinct 'compound semiconductor' made of silicon and carbon. It possesses entirely different electrical and thermal properties than pure silicon.
Because it contains the word 'Silicon', laypersons assume it is identical to the traditional silicon wafers that have dominated the computing industry for decades.
