亞太地區LED外延片：市佔率分析、產業趨勢與統計及成長預測（2026-2031年）

根據 Mordor Intelligence 預測，亞太地區 LED 外延晶片市場規模將從 2025 年的 11.3 億美元成長到 2026 年的 12.1 億美元，到 2031 年將達到 18.9 億美元，2026 年至 2031 年的複合年成長率為 9.3%。

本報告依材料系統（GaN基外延晶片、AlInGaP基外延晶片等）、基板類型（藍寶石、矽、碳化矽(SiC)、砷化鎵(GaAs)）、晶片直徑（100mm及以下、150mm、200mm以上）及應用（照明、汽車照明、通用顯示器和背光等）進行通用分類。市場預測以美元(USD)計價。

亞太地區LED外延晶片市場的趨勢與洞察。

MicroLED和MiniLED應用範圍的擴大

預計到2026年，主動式矩陣Mini-LED電視將佔全球出貨量的10%，這要求晶圓製造商在整個6吋基板上實現小於±2nm的波長分檔，以避免在HDR環境下出現色彩偏移。一級汽車製造商已開始將Mini-LED背光整合到儀錶群，推動了對低缺陷GaN外延的需求。三星顯示器和LG顯示器正在投資建造用於穿戴式裝置的Micro-LED試點生產線。與傳統LED相比，該領域每平方公尺面板所需的晶圓面積高達10倍，導致所需數量大幅增加。小米的163吋原型機展示了其可擴展性，前提是量產良率必須保持在1ppm以下。這些項目將推高平均售價，因為任何效能波動都會導致下游轉移過程中的返工。

高亮度汽車頭燈的需求增加

聯合國歐洲經濟委員會 (UNECE) 和修訂後的中國 GB 標準現已允許使用光通量超過 3000 流明且能抑制眩光的自我調整驅動光束模組。日亞化學工業株式會社 (Nichia Corporation) 的 DominoPLS 裝置每個模組整合 16 個可尋址段，並符合 UNECE 和 GB 的光度測試要求。印度的 AIS-199 標準草案符合全球標準，並為矩陣式頭燈開闢了新的區域發展道路。汽車原始設備製造商 (OEM) 要求峰值波長為 450 nm ± 5 nm，位錯密度小於 1 × 10^8 cm⁻²，這迫使外延製造商轉向使用更大尺寸的藍寶石或碳化矽 (SiC)基板以及先進的緩衝層。

藍寶石基板供應鏈的波動

預計到2026年，中國將佔全球藍寶石晶棒供應量的40%以上，但任何出口限制或物流中斷都將對亞太地區的晶圓廠產生直接影響。當智慧型手機相機蓋板的需求與顯示器需求高峰期重疊時，前置作業時間會更長，4吋晶圓的價格在每片15美元到25美元之間波動。印度的生產連結獎勵計畫（PLI）規定，三年內基板的在地採購率必須達到25%，但由於印度國內沒有藍寶石錠生產商，晶圓廠被迫簽訂多年進口契約，這削弱了補貼帶來的效益。

細分市場分析

2025年，氮化鎵（GaN）晶圓出貨量佔比達68.40%，主要成長動力來自通用照明、汽車和顯示器背光等領域。隨著各地政府採用無汞紫外線C波段（UV-C）消毒技術，亞太地區AlGaN LED外延晶圓市場預計到2031年將以12.87%的複合年成長率成長。日亞化學工業株式會社（Nichia Corporation）的280奈米裝置實現了7.4%的電光轉換效率，展現了其商業性可行性，並有助於供水事業採購。

目前，通用型GaN（用於燈泡）和滿足波長均勻性±2 nm、缺陷密度小於1 cm²等規格的高階GaN或AlGaN晶圓的價格呈現兩極化。 AlGaN中鋁含量的增加提高了開裂風險，促使製造商嘗試使用氮化鋁緩衝層和脈衝橫向生長方法。因此，材料選擇取決於產能、外延應力和日益成長的紫外線需求（尤其是在醫療滅菌領域）之間的平衡。

由於藍寶石具有良好的晶格匹配性和成熟的反應釜化學工藝，預計到2025年，其市場佔有率將達到55.67%。矽基基板的複合年成長率（CAGR）為13.58%，這得益於200毫米晶圓的普及和​​半導體級測量技術的進步，從而降低了單晶片成本。 Innoscience公司在8吋GaN-on-SiIC晶圓上實現了97%的良率，這得益於其採用了梯度AlGaN緩衝層和即時應力監測技術。

碳化矽由於成本高出3-5倍，仍然是一種小眾材料，但它為高電流LED提供了無與倫比的導熱性能。砷化鎵用於紅色和琥珀色AlInGaP，但其直徑有極限。因此，亞太地區LED外延晶片市場的佔有率平衡取決於顯示器和汽車行業的客戶是優先考慮成本還是散熱裕度。

第7章 市場機會與未來展望

According to Mordor Intelligence, the asia-Pacific lED epitaxial wafer market size is expected to grow from USD 1.13 billion in 2025 to USD 1.21 billion in 2026 and is forecast to reach USD 1.89 billion by 2031 at 9.3% CAGR over 2026-2031.

This report is Segmented by Material System (GaN-Based Epitaxial Wafers, Alingap Epitaxial Wafers, and More), Substrate Type (Sapphire, Silicon, Silicon Carbide (SiC), Gallium Arsenide (GaAs)), Wafer Diameter (Up To 100 Mm, 150 Mm, 200 Mm and Above), and Application (General Lighting, Automotive Lighting, Displays and Backlighting and More). The Market Forecasts are Provided in Terms of Value (USD).

Asia-Pacific LED Epitaxial Wafer Market Trends and Insights

Expansion of Micro-LED and Mini-LED Applications

Active-matrix Mini-LED televisions reached 10% penetration in global shipments in 2026, compelling wafer makers to achieve wavelength binning tighter than +-2 nm across 6-inch substrates to avoid color-shift artifacts under HDR conditions. Tier-1 automakers have begun equipping high-end instrument clusters with Mini-LED backlights, reinforcing demand for low-defect GaN epitaxy. Samsung Display and LG Display are funding Micro-LED pilot lines for wearables, where each square meter of panel uses up to ten-times more wafer area than conventional LEDs, multiplying volume requirements. Xiaomi's 163-inch prototype validated scalability, contingent on mass-transfer yields below one-ppm defect rates. These projects elevate average selling prices because every performance drift incurs rework in downstream transfer processes.

Rising Demand for High-Brightness Automotive Headlamps

UNECE and updated Chinese GB regulations now allow adaptive-driving-beam modules that exceed 3 000 lumens while controlling glare. Nichia's DominoPLS devices integrate 16 addressable segments per module, meeting both UNECE and GB photometric test requirements. India's draft AIS-199 standard aligns with global norms, opening a new regional route for matrix headlamps. Automotive OEMs stipulate peak wavelengths at 450 nm +-5 nm and dislocation densities below 1 X 10^8 cm-2, pushing epitaxial houses toward larger sapphire or SiC substrates with advanced buffer stacks.

Supply Chain Volatility of Sapphire Substrates

China will supply more than 40% of global sapphire ingots by 2026, but any export controls or logistical disruptions will instantly reverberate across Asia-Pacific fabs. Lead times stretch when smartphone camera-cover demand overlaps display peaks, sending 4-inch wafer prices swinging between USD 15 and USD 25 apiece. India's PLI rules require 25% local substrate value within three years, yet no domestic ingot producer exists, forcing fabs to lock multi-year import contracts that dilute subsidy benefits.

Other drivers and restraints analyzed in the detailed report include:

1. Rapid Urban Smart-Lighting Initiatives
2. Government Subsidies for Regional Semiconductor Manufacturing
3. High Capital Expenditure for MOCVD Tools

Segment Analysis

GaN wafers dominated 68.40% of shipments in 2025 on the back of general lighting, automotive, and display backlighting. The Asia-Pacific LED Epitaxial Wafer market size for AlGaN is projected to expand at 12.87% CAGR through 2031 as municipalities adopt mercury-free UV-C disinfection. Nichia's 280 nm devices, delivering 7.4% wall-plug efficiency, validated commercial viability and sparked procurement from water-utility operators.

Pricing now bifurcates between commoditized GaN for bulbs and premium GaN or AlGaN wafers meeting +-2 nm wavelength uniformity and sub-1 cm-2 defect specs. Elevated aluminum fractions in AlGaN raise cracking risks, so producers are experimenting with aluminum-nitride buffer layers and pulsed lateral overgrowth. Material selection thus hinges on balancing throughput, epitaxial stress, and emerging UV demand, especially for healthcare sterilization.

Sapphire held 55.67% share in 2025 because of favorable lattice matching and mature reactor chemistries. Silicon substrates, growing at a 13.58% CAGR, leverage 200 mm wafer availability and semiconductor-grade metrology to reduce the cost per die. Innoscience demonstrated 97% yield on 8-inch GaN-on-silicon wafers after implementing graded AlGaN buffers and real-time stress monitoring.

Silicon carbide remains a niche due to a 3-5X cost premium, yet offers unmatched thermal conductivity for high-current LEDs. Gallium-arsenide serves red-amber AlInGaP but is diameter-limited. The Asia-Pacific LED Epitaxial Wafer market share balance, therefore, depends on whether display and automotive clients prioritize cost or thermal headroom.
