Abstract:
Radio frequency (RF) circuits generate noise that can interfere with other RF circuits on the same semiconductor die. An isolation material disposed in an isolation region between a first active region of a first RF circuit and a second active region of a second RF circuit comprises a porosified region of the semiconductor material of the semiconductor die. The isolation material (e.g., porosified material) has a higher resistivity and lower permittivity than the semiconductor material to reduce transmission of noise interference between the first RF circuit and the second RF circuit. The isolation material in the isolation region of the semiconductor material comprises a porosity in the range 20% to 50% higher than the porosity of the semiconductor material in the first and second active regions. The porosified region has a lower permittivity and a higher resistivity than the non-porosified region to protect against the transmission of noise interference.
