Epitaxial Wafer Market
Epitaxial Wafer, also known as Epi-wafer is placed over other silicon wafer through epitaxial process. Epitaxy is a process in which a monocrystalline silicon layer is deposited over the polished crystal surface of a silicon wafer. This wafer acts as semiconducting substrate for applications such as microelectronics, photovoltaic, and photonics. There are two types of epitaxial wafer named; Homoepitaxy and Heteroepitaxy.
Major factor driving growth of the epitaxial wafer market is increasing use of LED lighting across the globe and this is fueling demand for epitaxial wafer. For instance, according to Coherent Market Insights’ analysis, the rate of LED lighting penetration in 2015 was 15% and it has increased to 27% in 2016, globally. The factor attributed to growth of LED lighting is increasing demand for energy efficient lighting products that help in reducing consumption of electricity and this is a major factor for replacing conventional lighting products with LED lighting across residential, commercial, and industrial sectors. LED lights are mainly incorporated with number of ICs. These ICs are manufactured from silicon wafer chip as silicon wafer is a cheap semiconductor that can easily slice into wafers, and subject to CMOS processes to turn each wafer into thousand ICs. Thus, in order to increase the performance of silicon wafer, the manufacturer coats this silicon wafer with epitaxial layer. This growth of epitaxial layer over silicon wafer helps in increasing electrical characteristic of the wafer, which in turn increases the power capability of LED lighting.
Initial high capital investments will restrict small players to enter in the semiconductor manufacturing sector. This factor will further restrict growth of epitaxial wafer market in the near future.
Increasing silicon wafer shipments is further driving growth of the market. For instance, according to SEMI (a global industry association serving the manufacturing supply chain including Semiconductors, Sensors, High-Brightness LED, Photovolatics PV, Flat Panel Display, Micro-ElectroMechanical Systems, and Flexible, Hybrid and Printed Electronics), total silicon wafer area shipments reached 3,255 million square inches during the third quarter of 2018, a 3.0% rise from the 3,164 million square inches shipped during the second quarter of 2018.
Global Epitaxial Wafer Market: Regional Insights
The market for epitaxial wafer in Asia Pacific accounted for largest share in the global market in 2017. The factor attributed to growth of this market is increasing penetration of smartphones, increasing adoption of IoT, self-driving cars, and others. For instance, according to the Coherent Market Insights’ analysis, the number of smartphone users in India was 292.6 million in 2016 and it has grown to 342 million in 2017. Increasing demand for smartphones and advancement in smartphone technology has led to development of thinner and smaller ICs. These silicon wafers form the building blocks of semiconductors, and semiconductor devices or chips are fabricated on these substrates. These semiconductors are then used in electronic devices ranging from computers to consumer electronics, telecommunication products, etc. Hence, growing demand for these electronic products is driving manufacturers to coat this wafer with epitaxial wafer that further increase the power of these electronic devices. Therefore, this factor is expected to propel demand for epitaxial wafer in the region over the forecasted period.
Moreover, presence of key manufacturers such as Samsung, Sony, LG, Toshiba, Panasonic, Toyota, and Honda makes this region largest consumer of semiconductor ICs. The presence of players accelerates manufacturing of ICs. Hence, this will be another factor resulting in increasing demand for epitaxial wafer in this particular region.
