摘要
A radio frequency fully depleted silicon on insulator (RF-FDSOI) device and method of fabrication are provided. A silicon wafer for digital circuits is constructed using fully depleted silicon on insulator technology having a thin buried oxide layer. Localized areas of the silicon wafer are constructed for radio frequency circuits and/or passive devices. The silicon wafer has a silicon substrate having a resistivity greater than 1 KΩ·cm. The localized areas of the silicon wafer may include a trap rich layer implanted underneath a thin buried oxide layer. The localized areas of the silicon wafer may include a buried oxide layer that is thicker than the thin buried oxide layer. The thicker oxide layer is between 20 and 2000 nm thick. The localized areas of the silicon wafer may include a trap rich layer implanted underneath the thicker buried oxide layer.
