Silicon Wafers

Sil'tronix Silicon Technologies aims to manufacture monocrystalline silicon wafer from its own ingot pulled at its facility. The entire production is made internally in order to maintain a reliable and qualitative consistency.

The major source of motivation for the company is to provide the most suitable silicon wafers regarding the customer requirement. It is the reason we manufacture the products on demand regarding individual specification (size, off cut, accurate resistivity… ).


We manufacture any diameters from 1’’ (25.4 mm) to 6’’ (152.4 mm) in order to provide the most flexibility as possible. With the aim of providing the maximum range of specification, we work either Cz (Czochralski) or FZ (Float Zone) silicon wafers.

To produce a qualitative products, pure silicon (9N) raw material is used.

The polishing process is also made internally by ourselves, in order to meet or exceed the Semiconductor Equipment and Materials International standards (SEMI).

Sil'tronix ST maintains a large inventory of Cz, FZ, low defect, ultra-flat and ultra-thin wafers.

Downsizing - Edge grinding

Downsizing-retouché.jpgTo match your own specification, we downsize silicon wafer on the size requested:

  • Downsizing by laser cutting (ie: 6" -> 3x2")
  • Round, flat, edge grinding
  • Specific edge profile: cutting 45° angle
