PJSC Semiconductor Plant has a long and proven history of polysilicon production dating back to 1964. In 2008, Activ Solar launched a comprehensive modernization program of Semiconductor Plant. The latest technologies will complement over four decades of expertise to create a state-of-the-art facility.

Located in the industrial heartland of Ukraine, PJSC Semiconductor Plant benefits from close proximity to raw materials and competitive energy and labour costs. In-house production of all utilities, managed by a highly experienced team provides an optimal platform for production, growth and on-going cost reduction.

As originally part of the Zaporozhye Titan & Magnesium Plant (ZTMP) complex, the facility started producing semiconductor-grade silicon in 1964. In the early 1990s, it produced 2.1% of global polysilicon supply and was the only manufacturer of high-purity TCS in the USSR. In 2002, it was separated from ZTMP and became PJSC Semiconductor Plant.
