Abstract
Processes and systems to fabricate high throughput, low cost tubular polysilicon feed rods, which can be used as direct feedstock to grow a crystalline silicon material, are disclosed. In an example, a chemical vapor deposition (CVD) process includes depositing polysilicon on a tubular electrode to form a tubular polysilicon feed rod. The tubular polysilicon feed rod may be melted in a float zone process to grow the single-crystalline silicon material.
