預計到 2025 年,磷酸銦晶片市場規模將達到 1.9817 億美元,到 2026 年將達到 2.2142 億美元,到 2031 年將達到 3.8565 億美元,2026 年至 2031 年的複合年成長率為 11.73%。

超大規模資料中心的現代化正在推動對 800G 和 1.6T光纖通訊設備的需求,而 5G 的全球部署、6G回程傳輸的籌備以及對量子光電投資的增加進一步促進了這一需求。大直徑基板降低了單位成本,而 InP-on-Si 混合平台則有望實現更高的可擴展性。亞太地區的整合化合物半導體生態系統構成了供應基礎,但歐洲和美國的回流計畫正在加速國內產能的擴張。由於晶體生長技術、長期客戶認證以及高額資本投入阻礙了新進入者,市場競爭仍然較為溫和。
雲端服務供應商向 800G 和 1.6T 連結遷移時,需要能夠以所需速度運作的邊發射雷射和光電二極體,而只有磷化銦 (InP) 才能滿足這些需求。相干公司 (Coherent) 在 2024 年第四季將其 InP 裝置產量提高了兩倍,並已開始提供 3.2T 收發器的樣品。 Source 光電展示了一款採用 InP 基底組件的 1.6T連貫模組,證實了該材料在共封裝光學元件中的不可或缺性。隨著交換器 ASIC 向 51T頻寬發展,插件式光學元件正轉向板載雷射引擎,從而降低了磷化銦晶圓市場對基板的需求。
商用 5G回程傳輸的工作頻率高於 28 GHz,在該頻段,InP HBT 的截止頻率可超過 450 GHz,耐壓可超過 4.5 V。諾基亞以 23 億美元收購 Infinera,獲得了傳輸節點的 InP連貫技術。早期探索兆赫頻率的 6G 測試平台依賴檢驗頻率高達 610 GHz 的 InP HEMT。因此,磷化銦晶圓市場對基板的需求不斷成長,不僅用於光前端,也用於射頻鏈路。
中國於2024年擴大對含銦化合物的出口限制,加劇了價格波動和前置作業時間的不確定性。儘管歐美晶圓製造商目前正在認證鎵和磷的替代供應商,但實現原料自給自足仍需時日。連貫的CHIPS專案在一定程度上緩解了風險,但短期採購壓力正在拖累整個銦磷晶圓市場的利潤率。
2025年,100毫米規格的磷化銦晶圓仍將佔43.72%的市場佔有率,主要滿足主流收發器產品線對成本和良率平衡的需求。在諾基亞採用AIXTRON G10-AsP反應器的6吋試驗生產線的推動下,向150毫米基板的過渡正在穩步推進。預計150毫米規格的磷化銦晶圓市場將以13.15%的複合年成長率成長,與砷化鎵的成本差距可望縮小。然而,尺寸超過6吋時機械強度的降低阻礙了晶圓尺寸的進一步縮小,而對76.2毫米晶圓的需求在對厚度均勻性要求嚴格的專業光電應用中依然強勁。
擴大大直徑晶圓的生產取決於專為低模量晶體設計的載片和邊緣夾持設備的投資。連貫在德克薩斯州的擴建計畫將採用自動化處理來減少破損,並力爭超過 85% 的優質晶圓良率。同時,50.8 毫米晶圓仍廣泛應用於大學的研究和開發領域,因為升級設備的成本極為高。因此,到 2031 年,磷化銦晶圓市場將同時存在多種直徑規格的晶圓。
到2025年,未摻雜導電基板將以36.18%的市場佔有率佔據主導地位,為光子積體電路的外延生長提供支援。隨著5G射頻功率放大器(需要基板隔離以實現低雜訊)需求的成長,半絕緣鐵(Fe)摻雜晶圓預計將以12.93%的複合年成長率成長。 N型錫(Sn)摻雜和P型鋅(Zn)摻雜晶圓主要用於HEMT和HBT裝置,但與用於射頻前端應用的磷化銦晶圓市場中鐵(Fe)摻雜晶圓的快速成長相比,它們的產量仍然較小。
對兆赫積體電路的研究凸顯了背景摻雜濃度對300 GHz增益的影響。費迪南德·布勞恩實驗室的異質接面雙極電晶體(HBT)透過最佳化鋅補償,實現了超過450 GHz的運作頻率(fT),凸顯了基板摻雜分佈如何支援系統級性能的提升。量子光電實驗室對超高純度、未摻雜晶圓的需求日益成長,但此類晶圓的成本是標準導電級晶圓的三倍,導致價格彈性有限。
預計到2025年,亞太地區將佔全球銷售額的41.55%,複合年成長率(CAGR)為12.41%。日本JX Nippon Mining & Metals已建立起精煉銦和磷原料的垂直整合供應體系,而台灣的Visual Photonics Epitaxy正在擴大用於資料通訊通訊雷射的100毫米晶圓的生產。韓國的先進材料生態系統為MOCVD製程提供耗材,增強了區域流動性。然而,由於中國原料法規的複雜性,出口許可證的核准流程也較為複雜,這為日韓生產商帶來了避險的需求,他們或許能夠在磷酸銦晶圓市場獲得溢價。
北美市場佔有率受益於聯邦政府的獎勵。相干公司(Coherent)獲得了3,300萬美元的CHIPS津貼,用於擴大其位於德克薩斯州的150毫米生產線的產能,從而保障了量子計算和國防領域的供應鏈。麻省理工學院林肯實驗室等高校正在研發用於低溫量子位元控制的InP-on-Si發射器原型,為未來的商業性需求奠定了基礎。然而,國內原料對海外供應的依賴仍是成本結構的一大挑戰。
歐洲正充分利用德國和荷蘭深厚的光電專業知識。費迪南德·布勞恩研究所正與弗勞恩霍夫IZM研究所合作,共同設計用於兆赫的InP HBT,而SMART Photonics公司則致力於推廣基於InP的光子積體電路(PIC)代工服務。弗賴貝格化合物材料公司供應位錯密度低於1e4 cm-2的VGF晶圓,並在量子通訊先導計畫中累積了豐富的應用經驗。歐盟的研究津貼正在補貼資本投資,但與亞洲競爭對手相比,能源價格的波動正在擠壓利潤空間,進而影響磷化銦晶圓市場的競爭格局。
The indium phosphide wafer market size is expected to grow from USD 198.17 million in 2025 to USD 221.42 million in 2026 and is forecast to reach USD 385.65 million by 2031 at 11.73% CAGR over 2026-2031.

Hyperscale data-center upgrades drive momentum to 800 G and 1.6 T optics, the global rollout of 5 G and preparation for 6 G backhaul, as well as expanding quantum-photonics funding. Larger-diameter substrates lower unit costs, while hybrid InP-on-Si platforms promise further scalability. Asia-Pacific's integrated compound-semiconductor ecosystem anchors supply, yet Western re-shoring programs are accelerating domestic capacity. Competitive intensity stays moderate because crystal-growth know-how, long customer qualifications, and high capex deter new entrants.
Cloud operators moving to 800 G and 1.6 T links require edge-emitting lasers and photodiodes that only indium phosphide can provide at the required speeds. Coherent tripled its InP-device output in Q4 2024 and is now sampling 3.2 T transceivers. Source Photonics demonstrated a 1.6 T coherent module using InP-based components, validating the material's indispensability for co-packaged optics. As switch ASICs advance toward 51T bandwidth, pluggable optics give way to on-board laser engines, reducing substrate volumes for the indium phosphide wafer market.
Commercial 5G backhaul operates above 28 GHz, where InP HBTs offer a cutoff frequency of more than 450 GHz and a breakdown voltage of more than 4.5 V. Nokia's USD 2.3 billion purchase of Infinera secures InP coherent expertise for transport nodes. Early 6G testbeds exploring terahertz frequencies rely on InP HEMTs, which have been validated up to 610 GHz. Consequently, substrate demand rises not only for optical front-ends but also for RF chains within the indium phosphide wafer market.
China's 2024 expansion of export controls to indium-bearing compounds elevated price volatility and lead-time uncertainty. Western wafer makers now qualify alternative gallium and phosphorus suppliers, yet achieving raw-material self-sufficiency cannot be done quickly. Coherent's CHIPS Act project mitigates some risk, but near-term procurement pressure trims margins across the indium phosphide wafer market.
Other drivers and restraints analyzed in the detailed report include:
For complete list of drivers and restraints, kindly check the Table Of Contents.
The 100 mm class retained a 43.72% indium phosphide wafer market share in 2025, catering to mainstream transceiver lines that strike a balance between cost and yield. A shift toward 150 mm substrates is underway, driven by Nokia's 6-inch pilot line utilizing AIXTRON G10-AsP reactors. The indium phosphide wafer market size for 150 mm formats is forecasted to grow at a 13.15% CAGR, narrowing the cost gap with GaAs. Yet, mechanical fragility above 6 inches restrains further scale, so 76.2 mm wafers remain relevant for specialty photonics that demand tight thickness uniformity.
Growth in large-diameter output hinges on investment in carriers and edge-grip tools designed for low-modulus crystals. Coherent's Texas expansion adopts automated handling to reduce breakage, targeting yields of over 85% for prime wafers. Meanwhile, 50.8 mm wafers persist in university R&D, where tooling upgrades are prohibitively expensive. A diverse diameter mix therefore co-exists within the indium phosphide wafer market through 2031.
Undoped conductive substrates led with a 36.18% share in 2025, underpinning photonic-integrated-circuit epitaxy. Semi-insulating Fe-doped wafers are projected to post a 12.93% CAGR, accelerating alongside 5G RF-power amplifiers that require substrate isolation for low noise. N-type Sn-doped and P-type Zn-doped slices target HEMT and HBT devices, but their volumes remain niche compared to Fe-doped growth in the indium phosphide wafer market size for RF front-ends.
Terahertz IC research highlights the impact of background dopant levels on gain at 300 GHz. The Ferdinand-Braun-Institut's HBTs utilized tailored Zn compensation to achieve a frequency of operation (fT) exceeding 450 GHz, underscoring how substrate doping profiles underpin system-level advances. Demand for ultra-pure, undoped wafers rises in quantum-photonics labs, but price elasticity is limited because such wafers can cost three times as much as standard conductive grades.
The Indium Phosphide Wafer Market Report is Segmented by Diameter (50. 8mm, 76. 2mm, and More), Wafer Doping Type (Undoped Conductive, and More), Application (Photonics and Optical Transceivers, and More), End-User Industry (Telecommunications and Datacom, and More), Manufacturing Technology (VGF-Grown Bulk, and More), and Geography (North America, South America, and More). The Market Forecasts are Provided in Terms of Value (USD).
Asia-Pacific retained 41.55% of revenue in 2025 and is projected to grow at a 12.41% CAGR. Japan's JX Nippon Mining and Metals provides a vertically integrated supply of purified indium and phosphorous feedstock, while Taiwan's Visual Photonics Epitaxy ramps 100 mm output for datacom lasers. Korea's advanced-materials ecosystem supplies MOCVD consumables, reinforcing regional liquidity. However, export-license complexities from China's raw-material controls create hedging demand for Japanese and Korean producers, who can command price premiums within the indium phosphide wafer market.
North America's share benefits from federal incentives. Coherent's USD 33 million CHIPS grant expands 150 mm line capacity in Texas to safeguard quantum-computing and defense supply chains. Universities such as MIT Lincoln Laboratory prototype InP-on-Si emitters for cryogenic qubit control, seeding future commercial pull. Yet domestic raw material dependence on overseas sources still challenges the cost structure.
Europe leverages deep photonics expertise across Germany and the Netherlands. Ferdinand-Braun-Institut collaborates with Fraunhofer IZM to co-design InP HBTs for terahertz radar, while SMART Photonics pushes foundry services for InP-based PICs. Freiberger Compound Materials supplies VGF wafers with <1e4 cm-2 dislocation density, securing design wins in quantum-communication pilots. EU research grants offset capex, but energy-price volatility narrows margins versus Asian peers, shaping competitive dynamics of the indium phosphide wafer market.
