Fig. 1Where the bets sit: windows from Early to Shut, left to right; each plot's area is the market's size by 2035. A double outline is a bull call, a single one a bear call, a dashed one a thesis with no call written yet. Washed: Sovereign electronics manufacturing, the largest bull call. 5 not yet sized are drawn small.
The marketsnumbered as the plan
  1. 12D materials
    • Bear
    • Early
    • $9.1B
    • Support 92
     Two-dimensional materials (graphene, hBN, MoS2, WSe2) reach high-volume manufacturing in at least one semiconductor or photonic application by 2028 (most likely thermal management films, EMI shielding, or UV LED substrates).
  2. 2Electron-informed materials discovery
    • Bear
    • Shut
    • $719M
    • Support 92
     In-situ electron-band-structure measurement during materials growth becomes the dominant materials-discovery substrate for semiconductors by 2030, displacing DFT screening and combinatorial atomic-scale exploration for interface-dominated problems.
  3. 3Back-end wafer prep equipment
    • Bear
    • Shut
    • $3.8B
    • Support 88
     Wafer thinning and singulation re-rates from a cyclical back-end niche to advanced-packaging-critical as HBM4 and 3D stacks multiply passes, but value stays locked in DISCO's near-monopoly
  4. 4Hybrid bonding
    • Bear
    • Shut
    • $919M
    • Support 88
     Hybrid bonding is the next high-density 3D interconnect, but the value is captured by the bonder duopoly + foundry, and the seed door is metrology/materials, not the bonder
  5. 5Legacy assembly
    • Bear
    • Shut
    • $82B
    • Support 85
     Traditional packaging is a mature, commoditised layer where profit is leaving for advanced packaging, and nothing in it opens with time.
  6. 6Advanced packaging metrology
    • Bear
    • Closing
    • $12B
    • Support 84
     The incumbents got there first: KLA, Onto and Camtek already ship the hybrid-bond and glass tools, so the AI packaging boom is a public-markets story.
  7. 7Known-good-die test
    • Bear
    • Closing
    • $7.7B
    • Support 84
     2.5D/3D integration makes known-good-die testing mandatory (one bad die scraps a multi-die package worth thousands) and AI-die power forces liquid-cooled / high-current burn-in.
  8. 8Trailing-edge capacity
    • Bear
    • Shut
    • $83B
    • Support 82
     Chinese mature-node (>=28nm) capacity additions in analog, power, RF and automotive silicon are building a structural OVERSUPPLY that compresses margins for the Western broad-line IDMs (Infineon, STMicroelectronics, NXP, onsemi) through the late-2020s, even as AI-exposed leading-edge parts stay in acute…
  9. 9Sovereign electronics manufacturing
    • Bull
    • Open
    • $65B
    • Support 82
     Automation-native vertical manufacturers break the EMS margin curse on sovereign demand
  10. 10Discovery metrology
    • Bear
    • Early
    • $23B
    • Support 82
     As AI makes candidate generation near-free, the binding constraint on discovery becomes the physical feedback loop, so value accrues to whoever owns the cheapest, fastest real-world oracle (metrology, characterisation, automated experiment)
  11. 11Ultrapure water and process fluids
    • Bear
    • Not dated
    • $28B
    • Support 80
     The fluid path into fabs and AI datacentres is bought as an annuity, and the annuity is why it repriced
  12. 12Advanced packaging
    • Closing
    • $86B
    • Support 79
     Packaging rent pools in materials, equipment and substrates, not OSAT assembly
  13. 13Deposition materials and process
    • Bear
    • Closing
    • $44B
    • Support 78
     Deposition value accrues to the molecule (precursors, inhibitors), never the tool
  14. 14Chiplets
    • Bull
    • Closing
    • $54B
    • Support 75
     Chiplet-based products grow from ~$3B (2021) to ≥$20B by 2027 at 40% CAGR, then capture ≥8% of total semiconductor revenue by 2030.
  15. 15Back-end test equipment
    • Bear
    • Shut
    • $33B
    • Support 73
     Restraints win: Advantest and Teradyne hold 90% of testers behind decades of qualification, and no standalone test company has reached venture scale. The growth goes to listed companies.
  16. 16Lithography and patterning
    • Early
    • $55B
    • Support 70
     ASML/EUV lithography is the #1 durable constraint on AI-compute scaling by ~2028-2030 (one supplier, more concentrated than memory).
  17. 17EDA and chip design
    • Bull
    • Closing
    • $62B
    • Support 67
     AI moves chip design onto the engineering bill; physical design and signoff sold per design is the layer the incumbents cannot copy without eating their seats.
  18. 18Lithography light sources
    • Bear
    • Early
    • $6.7B
    • Support 65
     The EUV source stays with ASML and Gigaphoton; the only small opening is mask-inspection sources, and nobody has shown up there yet.
  19. 19Computational lithography
    • Bear
    • Early
    • $2.6B
    • Support 64
     A European-founded company building AI-native mask synthesis tooling for specialty and research fabs (photonics, SiC/GaN, compound semi, photomask shops) will reach a paid pilot with at least one European mask shop before end-2028 without requiring direct qualification competition against Synopsys…
  20. 20Semiconductor metrology
    • Bear
    • Early
    • $1.1B
    • Support 64
     Semiconductor metrology is the highest-margin picks-and-shovels play adjacent to the litho stack
  21. 21Specialty 3D patterning
    • Bear
    • Early
    • $757M
    • Support 62
     There is a real, Tier-1-validated demand sub-segment for 3D/non-planar/thick-resist/curved patterning distinct from leading-edge EUV, but as with the parent the tool layer is incumbent-commoditised
  22. 22Photonic test and metrology
    • Bear
    • Shut
    • $3.9B
    • Support 58
     As CPO and silicon-photonics ramp, photonic test, known-good-die screening and active-alignment metrology become volume-gating (Teradyne flagged SiPh wafer/module test as the new bottleneck, Feb 2025).
  23. 23Nanotube electronics
    • Bear
    • Not dated
    • $333M
    • Support 58
     Carbon nanotubes used as electronics (transistors, memory, RF, sensors, and chip-process materials such as EUV pellicles) reach chip-industry volume first as fab consumables and sensors, by 2030.
  24. 24High-NA EUV
    • Bull
    • Shut
    • $32B
    • Support 56
     High-NA EUV lithography reaches widespread HVM availability by 2026, enabling sub-2nm logic nodes; manufactures $200B+ chips annually by 2030 as <10nm reaches 20-30% of total semiconductor production.
  25. 25Beyond-EUV lithography
    • Bear
    • Shut
    • $26B
    • Support 56
     No commercial semiconductor lithography platform beyond High-NA EUV (i.e.
  26. 26Photonic foundry capacity
    • Closing
    • $2.7B
    • Support 50
     By 2028, photonic IC foundry capacity binds production volume of co-packaged optics and photonic compute, with fewer than 5 commercial multi-project 300mm photonic foundries operating globally.
  27. 27Photonic PDK and EDA
    • Bear
    • Open
    • $1.7B
    • Support 46
     The asset-light way to play the photonic-foundry-capacity crunch is the PDK/EDA/design-automation layer every foundry and fabless team needs, where the moat is design IP and process-design-kit lock-in, not a 300mm fab
  28. 28Photonic multimaterial foundry
    • Bear
    • Early
    • $15B
    • Support 44
     A photonic foundry built ground-up for multi-material integration beats the silicon-first lines that bolt heterogeneity on
  29. 29Perovskite semiconductors
    • Bear
    • Early
    • $5.7B
     Perovskite emerges as a general-purpose semiconducting substrate, stability is the universal gating problem
  30. 303D heterogeneous integration production roadmap commitment

     TSMC SoIC, Intel Foveros, Samsung X-Cube moved from R&D demonstration to production roadmap commitment in 2025-2026.
  31. 31Ai-eda-verification-wedge
    • Not dated
     AI agents are already cutting chip verification time at named customers: Cadence reported up to 10x productivity at NVIDIA and Qualcomm in Feb 2026. The window is open, with the incumbents moving first.
  32. 32Area selective deposition
    • Not dated
     Annual industry coordination point for BEOL deposition tooling, financed by Tokyo Electron, Lam Research, Applied Materials, attended by GlobalFoundries.
  33. 33EU-sovereign advanced packaging tools
    • Not dated
     EU-sovereign capital equipment for sub-µm BEOL / advanced packaging (iCVD conformal coating, gridless ion beam thin-film deposition, direct-write 3D BEOL features) is structurally underbid relative to demand, because (a) the foundry fight has shifted from FEOL to BEOL+packaging, (b) most…
