Introduction (Covering Core User Needs & Pain Points):
Advanced packaging engineers, memory module designers, and semiconductor assembly specialists face a critical challenge: stacking multiple DRAM dies vertically (8-high, 12-high, 16-high) using Through-Silicon Vias (TSVs) in High Bandwidth Memory (HBM) to achieve ultra-wide interfaces (1,024-2,048 bits) and high bandwidth (1-2 TB/s) for AI accelerators (NVIDIA H100/B200, AMD MI300, Intel Gaudi), GPU, and HPC applications. Traditional die attach methods (capillary underfill (CUF)) require dispensing liquid underfill material after die stacking, but for narrow bump pitches (<40μm) and narrow gaps (<20μm) in HBM, CUF cannot flow completely, leaving voids and causing reliability failures (thermo-mechanical stress, popcorn cracking). The Non-Conductive Film for Semiconductor (HBM) – a pre-applied solid-type underfill film (B-stage epoxy resin with silica filler, 10-50μm thickness) applied to the wafer or die before dicing/staking – directly addresses these challenges by providing void-free underfill, precise gap control, and improved thermal-mechanical reliability. NCF is the core factor that determines heat dissipation (thermal conductivity) and semiconductor stack height (total height of stacked dies). However, HBM manufacturers (Samsung, SK Hynix, Micron) face complex choices: film thickness (10-25μm for fine bump pitch, 25-50μm for wider pitch), material supplier (Resonac, Henkel, NAMICS, WaferChem), compatibility with thermal compression bonding (TC-NCF) vs. mass reflow (MR-MUF) processes, and cost per wafer (US$ 10-50). This industry research report by QYResearch provides a data-driven roadmap for HBM manufacturers, advanced packaging foundries, and AI server supply chain managers. Global Leading Market Research Publisher QYResearch announces the release of its latest report “Non-Conductive Film for Semiconductor (HBM) – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. Based on current situation and impact historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global Non-Conductive Film for Semiconductor (HBM) market, including market size, share, demand, industry development status, and forecasts for the next few years.
Market Size & Product Definition:
The global market for Non-Conductive Film for Semiconductor (HBM) was estimated to be worth US12.18millionin2025andisprojectedtoreachUS12.18millionin2025andisprojectedtoreachUS 43.76 million by 2032, growing at a CAGR of 20.3% from 2026 to 2032.
Non-Conductive Film (NCF) is a pre-applied, solid-type underfill material used in 3D packaging (die stacking) for High Bandwidth Memory (HBM). HBM consists of stacking multiple DRAM dies (4, 8, 12, 16 dies) vertically using Through-Silicon Vias (TSVs) and micro-bumps (20-55μm pitch, 5-20μm bump height). NCF is applied to the wafer or individual dies before dicing and stacking. During thermal compression bonding (TC-NCF) or mass reflow (MR-MUF) process, the NCF cures (cross-links) to fill the gaps between stacked dies, providing mechanical support (reduces thermo-mechanical stress on micro-bumps), electrical insulation (prevents short circuits between adjacent bumps), corrosion protection, and thermal conductivity (heat dissipation from DRAM dies to heat spreader). In HBM, NCF is the core factor that determines heat dissipation (thermal conductivity of NCF directly affects junction temperature and lifetime) and semiconductor stack height (total height of HBM stack, which affects package integration and motherboard clearance). Key properties: (1) low coefficient of thermal expansion (CTE, 20-40 ppm/K, matched to silicon (3 ppm/K) and substrate), (2) high glass transition temperature (Tg > 150°C for lead-free solder compatibility (SnAgCu melting point 217-220°C)), (3) low modulus (flexibility to reduce stress), (4) fine filler particle size (<1-5μm) to flow into narrow gaps (<20μm), (5) low voiding (<1% after cure), (6) good adhesion to silicon, copper, and solder resist.

Section 1: Technology Segmentation – By Film Thickness and HBM Generation
The Non-Conductive Film for Semiconductor (HBM) market is segmented below by film thickness and HBM generation, with updated 2025 estimates:
By Film Thickness (2025 Market Share – QYResearch data):
- 10-25 μm NCF: 68% share (largest segment; used for fine bump pitch (20-30μm) and narrow gap (10-15μm) in HBM2E, HBM3, HBM3E, HBM4 (expected). Thinner film enables lower overall stack height (critical for ultra-thin mobile packages and for stacking more dies (12-high, 16-high) within same height budget. Requires smaller filler particle size (<1-2μm) and precise thickness uniformity (±1-2μm).)
- 25-50 μm NCF: 25% share (used for coarser bump pitch (40-55μm) in HBM2, older designs, or where wider gaps needed (e.g., for larger dies, or to improve thermal dissipation). Larger filler particles (2-5μm) acceptable. Lower cost than 10-25μm film.)
- Other (50+ μm, or custom thickness): 7% share (special applications, legacy HBM1, or non-HBM 3D stacking (logic-on-logic, sensor-on-logic))
By HBM Generation (2025 Market Share – QYResearch data):
- HBM3 (3rd generation, 8-12 stacks, 6.4 Gbps, 819 GB/s per stack): 38% share (largest segment; currently in mass production (Samsung, SK Hynix, Micron); NCF thickness 15-25μm typical)
- HBM2E (2nd generation enhanced, 3.6 Gbps, 460 GB/s): 28% share (legacy but still produced for some AI inference, networking applications)
- HBM3E (3rd generation enhanced, 8.0 Gbps, 1.0 TB/s+): 25% share (fastest-growing at 35% CAGR; introduced 2024-2025; used in NVIDIA H200/B200, AMD MI300X, other AI accelerators; requires thinner NCF (12-18μm) and higher thermal conductivity (k > 1.0 W/m·K) for 12-16 high stacks)
- HBM2 (2nd generation, 2.4 Gbps, 307 GB/s): 7% share (declining)
- Other (HBM1, HBM4 (pre-production): 2% share
Technical insight: TC-NCF (Thermal Compression Bonding with Non-Conductive Film) is the dominant process for HBM stacking (Samsung, SK Hynix, Micron). Process steps: (1) NCF film applied to wafer (lamination), (2) dicing into individual dies, (3) pick-up die with NCF, (4) thermal compression bond tool heats NCF above Tg (120-150°C), applies force (10-50N per die), and compresses micro-bumps into contact while NCF flows and cures, (5) post-bond cure (optional). TC-NCF enables precise bump alignment (±1-3μm), low voiding (<1%), and fine pitch (<30μm). However, TC-NCF is a sequential process (one die at a time), limiting throughput (600-1,200 dies per hour). MR-MUF (Mass Reflow with Mold Underfill) – a competing technology developed by SK Hynix and applied by others? – stacks multiple dies at once using a large oven and then injects liquid protective material (capillary underfill) into the space. MR-MUF has advantage: (1) higher throughput (batch processing), (2) lower pressure required for stacking (reduces die cracking risk for thin dies (<50μm)), (3) bumps melt and cure at desired location (better self-alignment). However, MR-MUF cannot use pre-applied NCF; requires liquid underfill injection after stacking (CUF). The industry is divided: Samsung and Micron use TC-NCF (NCF-based); SK Hynix uses MR-MUF (CUF-based) for HBM3/HBM3E but may adopt NCF for HBM4. NCF manufacturers will further enhance the technical update of NCF (higher thermal conductivity (k > 1.5 W/m·K), lower CTE (<15 ppm/K), lower modulus (<5 GPa), finer filler particle size (<500nm for sub-10μm gaps) to compete with MR-MUF and to enable HBM4 (16-high stacks, 9.6-12.8 Gbps, 1.5-2.0 TB/s per stack, <20μm bump pitch, <15μm gap). A key advancement in the past six months (Q4 2025-Q1 2026) is the introduction of “high thermal conductivity NCF” (k > 2.0 W/m·K) by Resonac and Henkel using boron nitride (BN) or alumina (Al₂O₃) filler loading (60-70% volume fraction) without increasing viscosity or voiding. Standard NCF has k = 0.3-0.8 W/m·K; high-k NCF reduces thermal resistance of HBM stack by 30-50%, lowering junction temperature (Tj) by 5-10°C at same power, enabling higher power density (30-40W per HBM stack) for AI accelerators. Samsung (HBM3E) and Micron (HBM4) are qualifying high-k NCF for 12-high and 16-high stacks.
By Application (End-User Manufacturer – 2025 Data):
- Samsung Electronics (South Korea): 45% share (estimated; uses NCF for HBM2E, HBM3, HBM3E; supplier relationships: Resonac, Henkel, NAMICS)
- SK Hynix (South Korea): 35% share (primarily uses MR-MUF (liquid underfill) for HBM, not NCF; but small percentage (10-15% of their HBM) using NCF for certain customers or products) – Note: The report states “the main producers of HBM using non-conductive films in the market are only Samsung and Micron”, indicating SK Hynix is not a NCF user (or minimal).
- Micron Technology (USA): 20% share (uses NCF for HBM2E, HBM3, HBM3E; supplier relationships: Resonac, WaferChem (maybe), Henkel)
Section 2: Competitive Landscape – Resonac Dominates
Key suppliers (NCF manufacturers): Resonac (Japan – former Showa Denko Materials (Hitachi Chemical), market leader (estimated 50-60% share); broad NCF portfolio (for HBM2/HBM2E/HBM3/HBM3E, and logic stacking); strong R&D in high-k NCF; qualified by Samsung and Micron), Henkel (Germany – second-largest, 20-25% share; NCF for HBM (Loctite brand); strong in semiconductor packaging materials; qualified by Samsung), NAMICS (Japan – 10-15% share; NCF for HBM and 3D packaging (underfill films)), WaferChem (China – 5-10% share; emerging supplier for Chinese domestic HBM development (CXMT, YMTC, ChangXin Memory Technologies (CXMT) are developing HBM? not yet mass production). Competition among suppliers will intensify during the forecast period (20.3% CAGR, high growth market). Suppliers will compete to provide competitive advantage based on pricing (ASP: US$ 0.50-2.00 per 12-inch wafer equivalent), value-added benefits (higher thermal conductivity, lower CTE, finer particle size), and service mix (technical support for TC-NCF process optimization, joint development for HBM4/HBM4e).
Downstream users (HBM manufacturers) are limited to Samsung and Micron (SK Hynix uses MR-MUF, not NCF). This concentrated downstream base means NCF suppliers have few customers (duopoly/monopsony) – high bargaining power for HBM manufacturers (price pressure). However, HBM manufacturers require dual sourcing (at least 2 qualified NCF suppliers per generation) for supply chain resilience, so Resonac and Henkel/NAMICS both have positions.
Section 3: Exclusive Industry Observation – AI Server Demand Drives HBM and NCF Market Growth
AI Server demand drives the market growth: The rise of AI Server (NVIDIA H100/H200/B200, AMD MI300X, AWS Trainium/Inferentia, Google TPU, Intel Gaudi) is likely to increase the demand for memory usage. With the increasing complexity of artificial intelligence models (GPT-5, Gemini 2, Claude 4, Llama 4, with trillion+ parameters), the demand for server HBM will grow simultaneously (each AI GPU typically has 80-192GB of HBM3/HBM3E, 6-8 stacks per GPU). Non-conductive film is an indispensable key material for HBM (for Samsung and Micron HBM). The artificial intelligence server market demand is still growing (AI server shipments projected 1.5-2.0 million units in 2027, up from 0.5-0.6 million in 2024), which also represents the market demand for non-conductive film will continue to grow.
A典型案例 (case study): NVIDIA’s B200 (Blackwell) GPU (expected 2025-2026 ramp) uses 8 HBM3E stacks (192GB total, 8 TB/s bandwidth). Each HBM3E stack is 12-high (12 DRAM dies stacked) using NCF (20-25μm thickness per layer). NCF consumption per HBM stack: 12 layers × 25μm NCF thickness (pre-bond) × die area (approx. 100mm² per die). NCF market value per HBM stack: approximately US2−5.PerB200GPU:8stacks×US2−5.PerB200GPU:8stacks×US 3.50 = US28worthofNCF.For1millionB200GPUs,NCFmarketaloneisUS28worthofNCF.For1millionB200GPUs,NCFmarketaloneisUS 28 million (2× total market size in 2025!). This case study illustrates how AI accelerator volume (NVIDIA, AMD, Google, AWS, Microsoft, Meta, Tesla) directly scales NCF demand. As HBM moves to HBM4 (16-high stacks, 9.6-12.8 Gbps, 1.5-2.0 TB/s, larger die area (120-150mm²)), NCF consumption per stack will increase by 30-50%, further driving market growth.
Section 4: Technological Innovation and Competition
Technological innovation plays an important role in driving market growth. To keep growing in a competitive market where suppliers are constantly developing new ideas and technologies, MR-MUF (Mass Reflow with Mold Underfill) is a new technology (SK Hynix) that welds multiple chips at a time in devices such as large ovens and then injects liquid protective materials (capillary underfill) into the space to protect and harden the circuits between the chips. Compared to existing TC-NCF technology, MR-MUF has the advantage of being able to reduce the pressure required for stacking (reducing die cracking risk) and make it possible for the bumps to melt and cure at the desired location (better self-alignment). MR-MUF also solves (to a certain extent) the problem of heat dissipation (higher thermal conductivity of mold underfill vs. NCF). NCF manufacturers will further enhance the technical update of NCF to improve all aspects of performance (higher k, lower CTE, finer filler, thinner films, improved flow) to compete with MR-MUF.
Key technical challenges for NCF: (1) void control at narrow gaps (<15μm) – gas trapped during bonding expands during reflow creating voids; vacuum lamination and bonding, outgassing optimization required, (2) die warpage control – mismatched CTE between NCF, silicon die, and substrate causes warpage; filler loading, modulus tuning, (3) thermal conductivity vs. filler loading trade-off – higher filler loading increases k but increases viscosity and void risk; filler shape optimization (spherical BN vs. platelet BN), bimodal particle size distribution.
Recent industry developments include: (1) JEDEC HBM4 standard (expected 2026-2027) – 16-high stacks, 9.6-12.8 Gbps per pin, 2,048-bit interface (from 1,024-bit for HBM3), 1.5-2.0 TB/s per stack; will require NCF thickness <15μm (for 16 dies within same height budget), k > 1.5 W/m·K, (2) Resonac “NCF-4″ series (2026) – for HBM3E and HBM4, with sub-500nm filler, k=1.8 W/m·K, CTE=22 ppm/K, (3) Henkel “LOCTITE ABLESTIK NCF 10″ (2025) – for 10-15μm gap applications.
Section 5: Market Forecast and Strategic Outlook (2026-2032)
By 2032, Asia-Pacific (South Korea (Samsung, SK Hynix), Japan (Resonac, NAMICS), Taiwan, China (WaferChem, emerging domestic HBM suppliers) will remain the largest market (85-90% share). North America (Micron) 10-12%, Europe <2%. 10-25μm NCF will remain largest segment (65-70% share). HBM3/HBM3E will be largest application by volume (40-45% share), with HBM4 growing to 25-30% share by 2030. The NCF market is projected to grow at 20.3% CAGR through 2032, driven by: (1) AI server demand (HBM content per AI accelerator increasing), (2) HBM3E and HBM4 adoption (12-high and 16-high stacks), (3) potential adoption of NCF by SK Hynix for HBM4 (if they switch from MR-MUF to NCF for finer pitch (<20μm)), which would increase total addressable market by 50%. Key success factors for NCF suppliers: (1) high thermal conductivity (k > 2.0 W/m·K), (2) fine filler size (<500nm) for sub-15μm gaps, (3) low voiding (<0.5%), (4) low total cost of ownership (consistent yield, minimal process optimization required by HBM manufacturers), (5) qualification by Samsung and Micron (HBM leaders).
