Manufacturing support
Cut orientation, orientation tolerance, primary flat direction and drawing requirements can be reviewed before quotation.
Diameter, thickness, TTV, bow, warp, edge profile and handling requirements should be defined according to the downstream process.
SSP, DSP or lapped surfaces can be discussed with roughness, visual defect, particle and packing requirements.
FAQ
Please provide material grade, dopant, cut, diameter, thickness, TTV, bow, warp, polishing type, roughness, edge criteria, quantity and inspection requirements.
Optical-grade projects emphasize optical quality and surface finish, while SAW-grade wafers also require application-specific crystal orientation, flat direction and acoustic-device geometry.
Yes. Rotated cuts and drawing-defined orientations can be reviewed with orientation tolerance and reference-flat requirements.
