Photonics Epitaxial Wafers
Epitaxial devices are the key to improving the performance of semiconductor-reliant products like smartphones, tablets, datacenters, displays, and fiber-optic networks.
Epitaxial devices consist of nanolayers of semiconductor crystals that are uniformly deposited in sophisticated deposition tools to form an “epi-wafer.” Combining different semiconductor materials and dopants in an epi-wafer is the key step in determining the performance capabilities of photonics.
Custom epitaxy enables a variety of device applications ranging from BiFETs to LEDs.
