In electronic components, 'Epitaxial' is a term used in semiconductor manufacturing technology, and refers to a technology that forms a semiconductor layer with a critical growth process. This technology is used to improve the performance of semiconductor devices, especially in silicon-based semiconductor manufacturing.
Epitaxial deposition is the process of depositing one or more additional layers on top of an existing semiconductor prototype. This process is also called epitaxy and is usually done using methods such as Chemical Vapor Deposition (CVD) or Physical Vapor Deposition (PVD).
Epitaxial deposition is used for a variety of purposes:
Improved performance: Improves electron mobility and speed by forming a higher quality crystalline structure than the base material of semiconductor devices.
Doping: In the epitaxial process, specific atoms or ions can be doped to give desired electrical properties.
Improved Stability: The epitaxial layer has the same lattice structure as the underlying prototype, making it more stable than layers formed by other techniques.
Device Integration: Epitaxial processes are used to integrate multiple devices into a single semiconductor chip by depositing multiple layers.
Epitaxial deposition is considered a key technology in semiconductor manufacturing and plays a key role in improving the performance and efficiency of semiconductor devices. This technology forms the basis for the development of a wide range of products in the semiconductor industry, including high-performance microprocessors, memory chips, and LEDs.
