TechConnect Innovation Program

Fluidized bed reaction(FBR) process to manufacture a granular Polysilicon over 8N in quality and Continuous Czochralski(CCz) process to make high quality ingot with high throughput.

Technovalue Co., Ltd., California, United States


The “FBR process” is the technology that can produce “granular polysilicon” at much less cost than conventional process by using continuous (or periodic) seed-feeding and polysilicon-withdrawing. The “CCz process” is remarkable process to be able to pull out plural ingot products in a batch according to the continuous feeding process.

Primary Application Area: Renewable & Hydrogen Energy

Technology Development Status: Proven Manufacturability
