deposition. A film or layer is deposited on a substrate of dissimilar composition and is known
as heteroepitaxy deposition. Laying a film or layer on a surface or substrate of a similar level of
conformation is known as homoepitaxy. Growing demand for high end semiconductor
equipment and devices and energy efficient LED lights is fueling growth of the market for
epitaxial wafer, globally. Increasing focus on reducing the overall consumption of electricity
along with growing awareness of green technology among consumers have compelled
manufacturers to adopt eco-friendly and energy-efficient lighting for example LED lighting.
Some of the major factors responsible for growing dependence on epitaxial deposition are
reduction in the device failure at the time of implementation, and inspection of the epitaxial
layer which makes it free of imperfections. For instance, it has been observed that the addition
of an epitaxial layer on a transistor raises its breakdown voltage and increases the transistor's
switching speed. Furthermore, some of the benefits of epitaxial wafers include controlled
doping profile in a device structure and better physical properties.
Homoepitaxy is when the same material (or polytype) as the substrate is grown for example: Si
on Si, 4H-SiC on 4H-SiC. Heteroepitaxy is when a different material (or polytype) from the
substrate is grown for example: GaN on sapphire, 3C-SiC on 6H-SiC.
