Epitaxy is a kind of interface between a
thin film and a substrate. The term epitaxy (greek; "epi"
"above" and "taxis" "in ordered manner")
describes an ordered crystalline growth on a (single-) crystalline substrate.
It involves the growth of crystals of one material on the crystal face of
another (heteroepitaxy) or the same (homoepitaxy) material. The lattice
structure and orientation or lattice symmetry of the thin film material is
identical to that of the substrate on which it is deposited. Most importantly,
if the substrate is a single crystal, then the thin film will also be a single
crystal. Contrast with self-assembled monolayer and mesotaxy.
Some examples are molecular beam epitaxy, liquid phase epitaxy and vapor phase epitaxy. It has applications in nanotechnology and in the manufacture of semiconductor and photonic devices. Indeed, epitaxy is the only affordable method of high crystalline quality growth for many semiconductor materials, including the technologically important materials as SiGe, gallium nitride, gallium arsenide and indium phosphide, the latter used in devices for LEDs and telecommunications.
Epitaxial-growth means the crystal growth being conducted on crystal of substrate and disposed in accordance with foundation of substrate crystal phase.
Homoepitaxial means the growth of the same material as the substrate while heteroepitaxial means the growth of the different material from the substrate. Substrate wafer on which single crystal thin film deposited by epitaxial growth are generally called as epi wafer.
Silicon epi wafers are utilized for element of diode and transistor or substrate for IC such as bipolar type and MOS type.
Furthermore, multiple layer epi wafers and thick film epi wafers are often used for power device and contribute to smallness and energy-saving of various power-source products.
