Oxidized Silicon Wafer 12 Inch Double-Side ATOMFAIR®

The wafer requires specification of crystal orientation, conductivity type, and resistivity band before processing. Thermal oxidation and PECVD methods impose distinct thermal and chemical compatibility constraints on the substrate.

• Processing Method Compatibility: Thermal oxidation and PECVD processing routes require confirmation of the substrate's thermal budget and surface cleanliness to prevent contamination or delamination.
• Resistivity and Doping Constraints: Heavily doped wafers below 0.001 ohm.cm may exhibit increased surface reactivity during oxidation, requiring controlled ramp rates to avoid defect formation.
• Crystal Orientation Sensitivity: Oxidation rates and oxide quality vary with crystal orientation, with <111> surfaces oxidizing faster than <100>, necessitating orientation-specific process calibration.

Confirm the wafer's crystal orientation, conductivity type, and resistivity band with the supplier before processing. Specify the oxidation method and any custom dimensions to ensure compatibility with downstream integration.

Required Equipment: Thermal oxidation furnace or PECVD system, Wafer handling tweezers or vacuum wand

1. Confirm wafer specification
   Verify the crystal orientation, conductivity type, and resistivity band with the supplier to match the intended oxidation process.
2. Specify processing method
   Select thermal oxidation or PECVD and confirm the target oxide thickness and uniformity requirements.
3. Define custom dimensions
   Submit any custom size or edge profile requirements for feasibility review before quotation.
4. Prepare substrate surface
   Clean the wafer using a standard RCA or equivalent process to remove organic and metallic contaminants prior to oxidation.
5. Load wafer into processing tool
   Transfer the cleaned wafer into the oxidation furnace or PECVD chamber using cleanroom-compatible handling tools.

The 12-inch double-side oxidized silicon wafer provides a versatile platform for advanced semiconductor and MEMS applications, supporting multiple crystal orientations (<100>, <111>, <110>) and a broad resistivity range from heavily doped (<0.001 ohm·cm) to undoped (>100-20000 ohm·cm), with the choice of thermal oxidation or PECVD processing.

Positive

• Broad resistivity and doping options: Conductivity types (N-type, P-type, undoped high-resistivity) and a wide resistivity band from <0.001 to 20000 ohm·cm allow matching to diverse device requirements, from power electronics to high-frequency or photonic applications.
• Thermal oxidation and PECVD routes: Both thermal oxidation and PECVD processing are listed, enabling flexibility in oxide quality and deposition temperature constraints depending on the integration scheme.

Trade-offs

• Customization requires specification confirmation: Size, crystal orientation, conductivity type, and target resistivity must be confirmed before quotation, adding a pre-order validation step that may delay procurement.
