Capability

Good Thermal Expansion and Contraction Coefficient
Good Thermal Expansion and Contraction Coefficient

Silicon boats have the same thermal expansion and contraction coefficient with silicon wafers, which can help to avoid scratch and slip problems.


Ultra-High Purity Silicon Materials
Ultra-High Purity Silicon Materials

Compared with SiC products, silicon products use higher purity silicon materials (>9N) which can avoid metal contamination issues.


Excellent Reparability
Excellent Reparability

Compared with SiC products, silicon boat can be used despite minor damages or scratches. When the damage is severe, silicon boats can be sent back to DSTC for repair.


Short Lead Time
Short Lead Time

The normal lead time for silicon boats is only 3 months, and 45 days in case of emergency.
