Services

Sil’tronix ST is a leading manufacturer of high quality customized silicon wafers and crystals. All Si wafers are made internally from the pulling process (to create specific ingot) toward the cleaning in order to maintain a reliable and qualitative consistency.

In order to provide you the maximum of services to succeed to your topics, we share our knowledge and tools.

From your own Silicon ingot, own silicon wafer, silicon crystal or semi-finished products, we are able to provide you the services as described below.

CZ SPECIFIC INGOT

  • Charlotte-Le-Mesle-Photographe-Sil-Tronix-ST-Transformation-Lingot-1.jpgOrientation: (100) or (111)  
  • Dopant: P-Boron or N-Phosphorus
  • From conductive materials closed to 1 mOhm.cm
  • Undoped: no added dopant

High purity silicon (purity 9N) is melted in a crucible at 1425°C, usually made of quartz. A precisely oriented seed silicon crystal is dipped into the molten silicon. The seed crystal’s rod is slowly pulled upwards and rotated simultaneously...

Downsizing – Edge grinding

To match your own specification, we downsize silicon wafers on the size requested

  • Charlotte-Le-Mesle-Photographe-Sil-Tronix-ST-Downsizing.jpgDownsizing with different tools laser cutting (ie: 6" -> 3x2")
  • Round, flat, edge grinding
  • Specific edge profile: cutting 45° angle

Mirror and Silicon Blocks Refurbishment

Silicon Block Refurbishment 2- Sil'tronix.jpgThe quality of x-ray mirrors produced today is significantly better than that which was available 10 years ago. Consequently, there are many large optics installed worldwide with slope and roughness characteristics that can be improved. In addition mirror coatings degrade (surface contamination) over time resulting in performance reduction

Crystal characterized with X-ray topography from Sil’tronix ST and another supplier.

The topographers are recorded to a 20 keV photon energy and show a 40 mm long section of the 120 mm long crystals installed as a second crystal in a double crystal monochromator.

Both crystals show a very good crystallinity. The Si crystal from Sil’tronix ST is almost free of defects, while the one from the other supplier shows scratches on the surface, most probably due to the polishing process.

Silicon wafer Orientations

Silicon crystals are characterized by an orderly array of their atoms. In monocrystalline crystals, this arrangement is the same wherever the zone within the crystal.
