A recently granted patent (Publication Number: US11883845B2) discloses a method for forming an ultrasonic transducer device. The method involves a series of steps including depositing layers on a substrate, patterning these layers to create a transducer cavity, planarizing the layers, and bonding a membrane to the support layer. The process includes specific details such as the materials used for each layer (e.g., silicon oxide, silicon nitride), their respective thicknesses, and the techniques employed for planarization.

Furthermore, the patent also describes an alternative method for forming an ultrasonic transducer device, which includes depositing layers on a substrate, conformally depositing additional layers, and planarizing these layers to create the transducer cavity. Similar to the first method, specific details regarding the materials used, their thicknesses, and the overall process are outlined. This alternative method provides additional insights into the fabrication of ultrasonic transducer devices, offering a comprehensive approach for manufacturing such devices with precision and efficiency.
