Modern electronic, photonic, optoelectronic, fiber optic, renewable energy, electric power technologies have been made possible by a suite of III-V, II-VI and IV-IV compound semiconductor materials and devices. Some of the examples of the base materials used in various applications include GaAs, InP, InSb, SiC, GaN, AlN, CdTe, etc. Within the class of compound semiconductors, the III-V compounds have played a pivotal role in shaping the advanced technologies. This talk will address the state-of-the-art industrial manufacturing process for III-V compound semiconductor technology in use today. The following topics will be covered: (i) synthesis of compounds from elemental raw materials, (ii) bulk crystal growth, (iii) wafer (substrate) preparation, (iv) epitaxial thin film growth, (v) device structures, (vi) device fabrication processes, (vii) device packaging and (ix) device testing and analyses. Some of the technological applications of these devices for large scale products will be illustrated. The challenges and opportunities for future research and technological development will be discussed, featuring the advanced III-V alloy crystal growth and wafer processing technologies developed by United Semiconductors LLC for defense and aerospace applications. Finally, United Semiconductors LLC’s on-going effort for developing In-Space Manufacturing at the International Space Station (ISS) leveraging microgravity (µG) conditions will be presented.
