Silicon Nitride Wafer 8 Inch Single-Side Oxidation ATOMFAIR®

This wafer requires explicit confirmation of crystal orientation, SiO2 film thickness, conductivity type, resistivity band, and processing route before quotation. Substrate, surface treatment, and intended integration compatibility must also be confirmed to establish a valid configuration.

• Process route confirmation: State whether oxidation furnace or PECVD processing is required during quotation confirmation.
• Film thickness confirmation: Select the target SiO2 film thickness and confirm whether it falls within the conventional 100-500 nm band.
• Conductivity and resistivity selection: Specify the conductivity type and target resistivity band to define the starting material parameters.
• Substrate and integration compatibility: Confirm the substrate, surface treatment, and intended integration requirements with the technical sales team.

Use these steps to supply the required configuration details for quotation and procurement. Each parameter must be stated explicitly before a final specification can be established.

1. Confirm wafer size and surface
   Confirm the 8-inch diameter and single-side oxidation surface requirement.
2. Select crystal orientation
   Select the required crystal orientation from <100>, <111>, or <110>.
3. Specify SiO2 film thickness
   State the target SiO2 film thickness and indicate whether the conventional 100-500 nm range applies.
4. Define electrical parameters
   Define the conductivity type, either N-type, P-type, or undoped high-resistivity, and the target resistivity band.
5. State processing route
   State the requested processing route as either oxidation furnace or PECVD.
6. Verify compatibility
   Verify substrate, surface treatment, and intended integration compatibility with the technical sales team.

The Atomfair 8-inch single-side oxidation silicon nitride wafer (AF-SI-W-SINX-08IN-S046) offers broad tunability in SiO2 film thickness (5 nm to 10 μm) via oxidation furnace or PECVD processing, enabling precise film engineering. However, procurement requires upfront specification of crystal orientation, conductivity type, resistivity band, and processing route, introducing lead-time dependency for non-standard configurations.

Positive

• Wide SiO2 thickness range: SiO2 film thickness from 5 nm to 10 μm, with conventional 100-500 nm, supports diverse dielectric and passivation requirements in semiconductor and MEMS applications.
• Dual processing route flexibility: Oxidation furnace and PECVD processing options allow optimization of film density, step coverage, and thermal budget depending on downstream integration needs.

Trade-offs

• Specification-dependent lead time: Crystal orientation, conductivity type, resistivity band, and processing route must be confirmed before quotation, which adds procurement lead time and requires detailed user input.
• Standard vs. custom trade-offs: Non-conventional SiO2 thickness outside 100-500 nm or high-resistivity undoped substrates may necessitate custom runs, reducing availability and increasing cost for specialized research needs.
