InP-based epitaxial wafer demand will be promising for niche-market applications, particularly optical communication uses bolstered by continuous construction of large-size datacenters and ever-increasing demand for cloud services. Taiwan’s epi-wafer suppliers including Intelligent Epitaxy Technology (IntelliEPI), Visual Photonics Epitaxy (VPEC) and LandMark Optoelectronics are thus expected to sustain stable shipments in the second half of the year, according to industry sources.
