Advances in crystal growth for semiconductor materials

摘要

Microelectronics, opto-electronics, photonics, bio-electronics, high-power/high-temperature/high-frequency devices, electronics for harsh environments, MEMS (micro-electro-mechanical systems), lasers sensors and photovolatics, all require semiconductor wafers of large diameter, high-quality and low-ocst, for device fabrication. Although "silicon technology" has been synonymous with semiconductor technology, rencent breakthroughs in fiber optic communications, radar antennas, infra-red devices, semiconductor laser, cellular phones, outdoor TV's, etc. would not have been possible whtout the advancements in devices based on III-V and II-VI compounds, and oxides. Exiting applications await the availability of high-quality, low cost substrates of silicon carbide, gallium nitride, zine oxide and many other difficult-to-grow materials.
