Ultrasonic transducer device with multiple metal layers
A recently granted patent (Publication Number: US11988640B2) discloses an ultrasonic transducer device designed with a unique structure. The device includes a bottom electrode layer with specific configurations, such as a bottom layer of a first type metal, a top layer of the same metal, a second type metal between them, and at least one intermediate layer separating two discrete layers of the second type metal. Additionally, a bottom cavity layer is formed on the bottom electrode layer using a combination of chemical vapor deposition (CVD) SiO2 layer and an atomic layer deposition (ALD) Al2O3 layer.
Furthermore, the patent details a method for forming the ultrasonic transducer device, involving the sequential formation of layers of different metals and insulating materials to create the desired structure. The method includes steps like forming the bottom layer of a first type metal, adding a second type metal, and then forming the top layer of the first type metal with specific thickness ranges. The process also includes the formation of a bottom cavity layer using CVD SiO2 and ALD Al2O3 layers, along with the creation of a membrane support layer and bonding a membrane to seal the cavity. This innovative approach aims to enhance the performance and efficiency of ultrasonic transducer devices through a carefully engineered design and manufacturing process.
