Global Single Crystal AlN Substrate Wafer Market Strategic Research Report

Scope of the Report

The global Single Crystal AlN Substrate Wafer market size is predicted to grow from US$ 7.25 million in 2025 to US$ 59.88 million in 2032; it is expected to grow at a CAGR of 35.9% from 2026 to 2032.

This report studies the AlN substrate/wafer, currently the AlN wafer prepared by the Physical Vapor Transport (PVT) method.

Aluminum nitride (AlN) is an important blue and ultraviolet light-emitting material, which is used in ultraviolet/deep ultraviolet light-emitting diodes, ultraviolet laser diodes, and ultraviolet detectors. In addition, AlN can form a continuous solid solution with III nitrides such as GaN and InN, and its ternary or quaternary alloy can achieve continuous adjustment of its band gap from the visible band to the deep ultraviolet band, making it an important high-performance luminescence material.

AIN (aluminum nitride) single crystal substrate is expected as high efficiency, high frenquency electronical device and deep ultraviolet emitting element.

At present, although the AlN single crystal substrate prepared by the PVT method has been commercialized; the AlN substrate price is very high, which hinders its large-scale commercialization. In addition, the AlN single crystal grown by the PVT method is usually yellow or brown, and has poor light transmittance, which is not conducive to the preparation of deep ultraviolet light-emitting devices as a substrate.

Currently the major sizes of AlN wafer are 10mm, 15mm, 20mm, 25 mm, 30mm, 35 mm, 50.8 mm (2") etc. few players have developed the 60mm AlN wafer.

Global key Single Crystal AlN Substrate Wafer players cover HexaTech, Inc, ELECTRONICS AND MATERIALS, Crystal IS, Fraunhofer IISB, Tokuyama, etc.
