Epitaxial wafer - Wikipedia

An epitaxial wafer (also called epi wafer, epi-wafer, or epiwafer ) is a wafer of semiconducting material made by epitaxial growth (epitaxy) for use in photonics, microelectronics, spintronics, or photovoltaics. The epi layer may be the same material as the substrate, typically monocrystaline silicon, or it may be a more exotic material with specific desirable qualities. Silicon epi wafers were first developed around 1966, and achieved commercial acceptance by th… WebOct 12, 2011 · The introduction of the Candela tool to Epistar's manufacturing process provides automated inspection methods for sapphire substrates to ensure vendor … WebThe ideal for the inspection of EPI wafers. Un-patterned wafers inspection is becoming more critical due to the need to find defects earlier in the manufacturing process flow. Finding those defects is getting harder as critical dimensions shrink. Un-patterned wafer inspection looks for defects on unprocessed or bare silicon wafers. small maps of the world
