Products & Service

Sizing

SRS has developed a unique sizing process using TEOSS thermal cracking resulting 3 primary sizes of chips.

5-45 mm
15-30 mm
10-50 mm

Attributes

  • Very clean material leads to an improved dip ratio and reduces impurity-based LOS events.
  • Etched material reduces initial meltdown time.
  • Greater initial charge density increases throughput per heat cycle.
  • Feedstock enables top off and recharge technologies.
  • Essential to CCZ production.
  • Excellent morphology (cubic) minimizes potential for feed tube obstruction.

Etching

  • SRS unique “etching” capabilities satisfy 200mm semiconductor specifications:
    • SRS products typically have less than 1 ppbw of total surface metals (on aggregate of 18 metals)

Supply

  • Unquestioned stability for long-term supply of high-quality material.
  • Ability to provide a “target charge” of chunk and various chip sizes depending on application.
  • Flexibility of chip size range to suit specific production campaigns.
  • Chip size tailoring generally not available from other suppliers.
