Taiwan's Power Semiconductor Manufacturing Corporation (PSMC) has announced plans to build a 300mm wafer fab in Japan in collaboration with SBI Holdings. The purpose of this collaboration is to strengthen Japan's domestic IC (integrated circuit) supply chain, with a particular focus on circuits for AI edge computing and packaging technologies.

The application areas of SiC-based and Si-based GaN are not strictly separated. In GaN-On-SiC devices, the cost of SiC substrate is relatively high, and with the growing maturity of SiC long crystal technology, the cost of the device is expected to fall further, and it is used in power devices in the field of power electronics.

Both epitaxial and diffused wafers are essential materials in semiconductor manufacturing, but they differ significantly in their fabrication processes and target applications. This article delves into the key distinctions between these wafer types.

Homoepitaxy and heteroepitaxy play pivotal roles in material science. Homoepitaxy involves the growth of a crystalline layer on a substrate of the same material, ensuring minimal defects due to perfect lattice matching. In contrast, heteroepitaxy grows a crystalline layer on a different material substrate, which can lead to challenges like lattice mismatch. These processes are crucial in advancing semiconductor devices and thin films. For instance, heteroepitaxy significantly impacts microelectronics and quantum optics, contributing to innovations like Light Emitting Diodes.
