RF and linear performance of commercial 200 mm trap-rich HR-SOI wafers for SoC applications

Abstract

We present for the first time the RF and linear performance of commercial 200 mm trap-rich HR-SOI wafers. These wafers are fully compatible with the thermal budget of CMOS process. The investigated SOI wafers with a fixed BOX of 400 nm-thick show effective resistivity values higher than 4 kΩ-cm and harmonic distortion levels lower than −81 dBm for a 900 MHz input signal with +15 dBm, i.e. more than 95 dBc. Our investigations confirm the capability of trap-rich HR-SOI wafer for the integration of RF systems in Si.
