An Unprecedented Offering By Order of SunEdison: A Complete Sale of its World Class Polysilicon Plant Operations in Merano, Italy.

This plant has consistently upgraded its operations to the highest state of the art production capacity standards.

• Approximate Total Property: 102,475 mq
• Approximate Covered Area: 32,635 mq
• Approximate Open Area: 60,365 mq

The plant is an integrated facility starting from chlorosilane production and ending in polysilicon production for PV and EG applications.

Technological Highlights:

• All CVD reactors (12, 18, 36 and 54 rods) have been designed by SunEdison.
• TCS and STC purity is assured by a proprietary patented reactive distillation technology, very effective in removing Boron but also Posphorous and other metals.
• The overall process is designed and operated to handle DCS formation and allow to feed TCS + DCS to the CVD reactors.
• STC converters are designed internally and assure high STC conversion rate and low energy consumption.
• The Front End has been designed and constructed by Evonik Degussa AG.

Installed Capacity:

• Technical Grade Chlorosilanes:
• Up to 25,000 Metric Tons Annually

• Trichlorosilane Electronic Grade for Epitaxially grown silicon:
• Up to 600 Metric Tons Annually

• Siemens Based Polycrystalline Silicon:
• Up to 4,000 Metric Tons Annually – Photovoltaic Grade
• Up to 1,850 Metric Tons Annually – Electronic Grade for Microelectronics
