Advanced packaging in India: rising patent filings, thin startup activity

What it is

Advanced packaging is a set of techniques that integrate multiple semiconductor chips—often called chiplets—into a single package. It uses methods like 2.5D stacking (chips side-by-side on a silicon interposer), 3D stacking (chips stacked vertically with through-silicon vias), and fan-out wafer-level packaging to connect logic, memory, and other functions. The goal: higher performance, smaller size, and lower power consumption, pushing beyond the limits of traditional transistor scaling. (Lam Research, Wikipedia)

Think of it as a way to build a super-chip by combining specialized pieces rather than making one giant monolithic chip. This is critical for AI accelerators, high-bandwidth memory (HBM), and advanced smartphones. It's the hardware backbone that keeps Moore's Law alive in the age of AI.

The value chain

• Upstream – Design & EDA: Tools for multi-die system design, thermal analysis, and signal integrity. Dominated by Synopsys, Cadence, Ansys. High margin, IP-driven.
• Upstream – Materials & Substrates: Silicon interposers, glass substrates, molding compounds. Key suppliers: Shin-Etsu, Sumitomo, AGC. Defensible through material science.
• Upstream – Equipment: Wafer-level packaging tools, bonding, lithography, inspection. Applied Materials, ASML, KLA, Lam Research. Capital-intensive, high barriers.
• Midstream – Front-end Fabrication: Foundries like TSMC, Intel, Samsung integrate packaging into chip manufacturing (e.g., CoWoS, EMIB). Where much of the value and differentiation sits.
• Midstream – Advanced Packaging & Assembly (OSAT): Outsourced assembly and test providers like ASE, Amkor, JCET. Scale-driven, lower margin than foundry but essential.
• Downstream – Testing & Final Integration: Burn-in, system-level test. Often handled by OSATs or specialized firms. Quality and reliability gate.

Where it's heading

• Co-packaged optics (CPO) are set to go mainstream in 2026, with TSMC integrating its COUPE technology into CoWoS to slash power consumption in AI networking. (TechInsights)
• HBM demand is outstripping supply; HBM4 and 16-Hi stacks are pushing yield and thermal limits, making hybrid bonding a necessity. (TechInsights)
• Glass substrates and panel-level packaging are gaining traction, enabling larger form factors and reducing reliance on expensive silicon interposers. (TechInsights)
• Thermal management in 3D stacks is driving adoption of liquid cooling, advanced thermal interface materials, and back-side power delivery. (TechInsights)
• Chiplet architectures are moving beyond data centers into mobile devices, with 2026 likely marking the first smartphone designs using advanced packaging. (TechInsights)
• AI and HPC are the strongest growth drivers; the telecom & infrastructure segment is projected to grow at 14.9% CAGR through 2030. (Yole Group)
• India's advanced packaging market is valued at $2.5 billion in 2025 and is expected to reach $4.4 billion by 2032, an 8.3% CAGR. Gujarat is the largest state market, Tamil Nadu the fastest-growing. (P&S Market Research)

The opportunity in India

Our patent data shows rising filings in advanced packaging, a strong signal of growing inventive activity. However, only 9 patents are currently matched to the technology, and none are held by startups. This points to a wide-open field where Indian deep-tech entrepreneurs can build intellectual property.

The company landscape is similarly thin: just four firms in our dataset reference advanced packaging in their profiles. None have disclosed funding in this specific area. With a domestic market projected to hit $4.4 billion by 2032, there is ample room for startups to enter design services, specialty materials, or niche assembly and test.

The gap is especially pronounced in the upstream—EDA tools, substrates, and equipment—where global incumbents dominate. India's growing semiconductor fabrication ambitions (such as new ATMP and OSAT facilities) could create downstream demand for local packaging innovation, but the startup pipeline is yet to materialize.

India signal: patents, startups, capital

Patents: 9 patents in our dataset are mapped to advanced packaging. The filing momentum is rising, even before the last two years of confidential filings are fully published—indicating genuine growth in inventive activity.

Startups: Our data lists 4 deep-tech companies active in advanced packaging: Inferge Silicon (Hyderabad), MISA OILS (Pune), VELOX SUPPLY CHAINTECH (Gautam Buddha Nagar), and KIMUM PACKAGING SOLUTIONS (Sundargarh). Notably, none of these firms hold a patent in this technology, and none appear in our funding records.

Capital: No sector-specific funding was identified. The broader semiconductor funding landscape in India has focused on fabless design and AI chips, leaving advanced packaging largely unfunded in the startup ecosystem.
