Abstract
A structure of a semiconductor device is provided, including a circuit substrate. A first metal bulk layer is disposed on the circuit substrate. A buffer layer is disposed on the first metal bulk layer. An absorbing layer is disposed on the buffer layer. A first electrode layer is disposed on the absorbing layer. A plurality of piezoelectric material units are disposed on the first electrode layer. A protection layer is conformally disposed on the piezoelectric material units. A second metal bulk layer is disposed over the piezoelectric material units, and including a first part and a second part. The first part penetrating through the protection layer is disposed on the piezoelectric material units, serving as a second electrode layer. The second part is at a same level of the first part, and at least electrically connecting to the first electrode layer.
