Shop Silicon Wafers By Category

As a precision MEMS foundry, we select only the highest-quality silicon wafers for our internal use.  Why should you settle for anything less?  Now you can purchase the same high-quality silicon wafers we use to manufacture leading-edge micro devices.

Choose between bare silicon wafers or silicon wafers already coated with one of our signature thin films.

Our inventory of pre-processed wafers includes some of our most common oxide and nitride thin film variations:

Silicon Wafers with Thermal Oxide

All products ship with a certificate of conformance that includes silicon wafer specifications and thermal oxide thickness data.

About our thermal oxide

Our ultra-pure wet thermal oxidation process ensures that you receive the highest-quality films. Prior to thermal oxidation, all wafers receive a thorough inspection and pre-process clean.

Silicon Wafers with Dry Thermal Oxide

All products ship with a certificate of conformance that includes both the exact silicon wafer specification as well as with lot-specific dry thermal oxide thickness data

 

About our Dry Thermal Oxide

Our ultra-pure dry oxidation process is available for those applications requiring thinner oxides. It’s designed to ensure that you receive the highest-quality film on interface, which can affect the insulating properties of your oxide.

Silicon wafers with Dry Chlorinated Oxide

All products have received forming gas anneal to improve performance

 

About our Dry Chlorinated Thermal Oxide with Forming Gas Anneal

Our dry chlorinated thermal oxidation is ideal for MOS and other active device fabrication processes. Use dry chlorinated thermal oxide to eliminate metal ions, which can help your devices reach their highest performance. The addition of a forming gas anneal after oxidation passivates dangling bonds. Dangling bonds at the silicon interface can have a negative effect on the insulating properties of your oxide.

Silicon Wafers with Stoichiometric LPCVD Nitride

All products ship with a certificate of conformance that includes the silicon wafer specification along with nitride film stress and thickness data.

 

About our Stoichiometric LPCVD Nitride

Our stoichiometric LPCVD nitride film is often used as a tool for defining active regions during field oxidation. If planning to use nitride as a KOH mask for through-wafer etching, our low stress nitride or oxide/nitride film may yield the best results.

Silicon Wafers with Low Stress LPCVD Nitride

All products ship with a certificate of conformance that includes the exact silicon wafer specification along with film stress and thickness data.

 

About our low stress LPCVD nitride

Our low stress nitride offers multiple benefits. It retains all the attributes of our standard nitride and can also be used for membranes, cantilever beams and other mechanical structures associated with MEMS devices. This silicon rich film is also excellent as a KOH etch mask.

Silicon Wafers – 76mm Inventory

All products ship with a certificate of conformance that includes silicon wafer specifications.
