RF Epitaxial Wafers
Epitaxial devices are the key to improving the performance of semiconductor-reliant innovations such as smartphones, tablets, datacenters, displays, and fiber-optic networks.
Epitaxial devices consist of nanolayers of semiconductor crystals that are uniformly deposited using sophisticated deposition tools to form an epiwafer. Combining different semiconductor materials and dopants in an epiwafer is the key step in determining the performance capabilities of RF semiconductor components.
Coherent provides custom epitaxy for a variety of device applications, ranging from BiFETs to LEDs.
