  • Patent number: 11440052
    Abstract: An electronic device includes a plurality of CMOS control elements arranged in a two-dimensional array and a plurality of MEMS devices. Each CMOS control element of the plurality of CMOS control elements includes at least one of a low voltage semiconductor device, a high voltage PMOS semiconductor device, and a high voltage NMOS semiconductor device. Each MEMS device of the plurality of MEMS devices is associated with a CMOS control element of the plurality of CMOS control elements. The plurality of CMOS control elements are arranged in the two-dimensional array such that low voltage semiconductor devices are only adjacent to other low voltage semiconductor devices, high voltage PMOS semiconductor devices are only adjacent to other high voltage PMOS semiconductor devices, and high voltage NMOS semiconductor devices are only adjacent to other high voltage NMOS semiconductor devices.

  • Publication number: 20200400800
    Abstract: A Piezoelectric Micromachined Ultrasonic Transducer (PMUT) device is provided. The PMUT includes a substrate and an edge support structure connected to the substrate. A membrane is connected to the edge support structure such that a cavity is defined between the membrane and the substrate, where the membrane is configured to allow movement at ultrasonic frequencies. The membrane includes a piezoelectric layer and first and second electrodes coupled to opposing sides of the piezoelectric layer. An interior support structure is disposed within the cavity and connected to the substrate and the membrane.
