DOWA conductive GaAs
and separately sourced options
Origin and trade conditions are reviewed per order
Import and export requirements can vary by origin, destination, end user and end use. At quotation and contract stage, we identify the manufacturer, origin and specification documents and review applicable trade-compliance requirements for the transaction.
Information needed for quotation
- Wafer diameter and thickness
- Conductivity and doping, or semi-insulating type
- Orientation, surface finish and EPI structure
- Quantity, destination and end use
Supply routes
- DOWA: conductive VGF GaAs
- Semi-insulating and EPI: separately sourced globally
- Manufacturer, origin and specification stated in quotation
- Availability and compliance reviewed per transaction
Supply route by wafer type
DOWA conductive wafers and globally sourced items are identified separately rather than presented as one manufacturer's range.
