- Electronic-grade polysilicon is a highly purified form of silicon, also known as polycrystalline silicon. Electronic-grade polysilicon has been the material of choice for use in mainstream semiconductor devices and circuits. Polysilicon has semiconductor properties and, hence, it is widely used in solar power and electronics industries
- Polysilicon can be produced by using three major commercial processes: the Siemens process, the FBR process, and the upgraded process of metallurgical grade. Polysilicon obtained from the Siemens process is in the form of rods, whereas polysilicon obtained from the FBR process is granular
- Polysilicon is generally of two grades: solar and electronic. Solar-grade polysilicon is used in the manufacture of photovoltaic cells, while electronic-grade polysilicon is employed in the manufacture of integrated circuits, power conversion devices, optics, and microelectromechanical systems (MEMSs)

Rise in Demand for use of Innovative Production Process
- Rapid and ongoing expansion of their polysilicon production capacity by market players is likely lead to oversupply of polysilicon for the next several years, thereby prompting manufacturers of electronic-grade polysilicon to further innovate their production processes and reduce operating costs.
- For polysilicon production, manufacturers utilize silane gas as a precursor. This leads to a closed-loop process that can result in reduced costs. Also, it significantly reduces the environmental impact. It also enables production of high-quality polysilicon.
- Polysilicon plants that target the global electronic-grade polysilicon market use ultra-high purity hydrogen purifiers. It is helpful to remove typical impurities such as methane and nitrogen.
- Large gas plants produce primarily trichlorosilane (TCS) gas that are used in the production of semiconductor-grade polysilicon for both semiconductor and solar applications. This provides the manufacturer with flexibility to operate in the electronic-grade polysilicon market place. Hence, increase in use of innovative production process is expected to drive the growth of the market during forecast period.
