To our valued global customers and supply chain providers…

As we navigate through these challenging times, I wanted to reaffirm that GTAT is operating to meet its commercial obligations to you. Our production lines are running and we are following all health and government mandates and protocols. These include appropriate social distancing for necessary employees at our facilities, and enhanced cleaning and sanitizing measures. All GTAT employees able to work remotely are doing so, and they have access to everything needed to maintain normal operations throughout this global health emergency.

We wish all of our customers and providers the very best. We will get through this together.

Our patented, new Continuous Cz Feeder offers manufacturers of monocrystalline silicon wafers greater throughput capacity and lower costs – while producing a superior product. The innovative Continuous Cz Feeder process increases throughput by 15%, crystal yield by 10% and lowers operating cost by 15% compared with current batch Cz pullers. The continuous feeding process allows the Gallium dopant to be fed along with the polysilicon throughout the production cycle. This enables manufacturers to produce longer ingots with even resistivity throughout the length of the ingot, which increases yields, a key factor that helps lower the cost of mono wafers. Our Continuous Cz Feeder process solves the problem of light induced degradation (LID), a common problem associated with solar cells fabricated on boron doped p-type mono silicon wafers. Replacing boron with gallium solves the LID issue and eliminates the loss of cell efficiency due to LID. The Continuous Cz Feeder can be integrated with all high volume Cz furnaces currently in production.
