Heraeus Black Quartz HBQ® - Wafer

Heraeus Black Quartz is suitable for different applications. One example are wafers.

HBQ® is the ideal material for filler and dummy wafers in batch furnace deposition processes. The matched CTE (coefficient of thermal expansion) of the HBQ® wafer to SiO₂ makes HBQ® suited e.g. for TEOS or other SiO₂ deposition processes.

With HBQ® our customers can take advantage of different benefits:

• Improved layer adhesion
• Reduced wafer cleaning:
  Due to the optimized CTE HBQ® dummy wafer needs only to be cleaned and reclaimed a fraction of time compared to Silicon or SiC. This results in improved cleaning cycles that gives our customers a valuable benefit with respect to Cost of Ownership.
• Improved troughput:
  Due to extended cleaning cycles HBQ® wafers remain loaded in the boat without loading and unloading every process and thus improve our customers troughput.
• Improved Cost of Ownership:
  With a reduced number of cleaning cycles and improved wafer loading times HBQ® dummy wafers offer a unique way to optimize total Cost of Ownership.
