Publication number: 20240075499Abstract: MEMS ultrasonic transducer, MUT, device, comprising a semiconductor body with a first and a second main face, including: a modulation cavity extending into the semiconductor body from the second main face; a membrane body suspended on the modulation cavity and comprising a transduction membrane body and a modulation membrane body; a piezoelectric modulation structure on the modulation membrane body; a transduction cavity extending into the membrane body, the transduction membrane body being suspended on the transduction cavity; and a piezoelectric transduction structure on the transduction membrane body. The modulation membrane body has a first thickness and the transduction membrane body has a second thickness smaller than the first thickness. In use, the modulation membrane vibrates at a first frequency and the transduction membrane vibrates at a second frequency higher than the first frequency, to emit and/or receive acoustic waves at a frequency dependent on the first and the second frequencies.Type: ApplicationFiled: August 24, 2023Publication date: March 7, 2024Applicant: STMICROELECTRONICS S.r.l.Inventor: Francesco FONCELLINO
