The epitaxial wafer refers to manufacturing method that involves depositing a thin layer of a semiconductor material on a crystalline substrate or wafer in succession. It is widely used in power electronic devices, advanced LEDs, solar cells and semiconductor devices. The process is used to grow epitaxial layers like silicon, gallium arsenide or gallium nitride on a wafer substrate. These epitaxial layers are used as active layers in the fabrication of semiconductor devices and exhibit material properties and crystallographic orientations tailored to the specific device requirements. The global epitaxial wafer market is estimated to be valued at US$ 938.32 Bn in 2023 and is expected to exhibit a CAGR of 4.8% over the forecast period 2023 to 2030, as highlighted in a new report published by Coherent Market Insights.

Market Dynamics:

The demand for epitaxial wafers is primarily driven by rising adoption of silicon-based power electronics owing to their increasing usage in electric vehicles, fast charging infrastructure and renewable energy applications. Silicon-based power semiconductors have high-power handling capability and are cost-effective. Epitaxial wafers are used to grow ultrapure epitaxial silicon layers that act as the active region in power devices. Additionally, the growth in SiC and GaN power electronics is further fueling the demand for epitaxial wafer. SiC and GaN offer higher efficiency and power density compared to silicon. Growing electric vehicle production and demand for fast charging stations is expected to boost the epitaxial wafer market over the forecast period.
