Abstract
A method includes the following operations: forming a piezoelectric substrate including a piezoelectric structure and a conductive contact structure, in which the piezoelectric structure has a conductive layer and a piezoelectric layer in contact with the conductive layer, and the conductive contact structure is electrically connected to the piezoelectric structure and protrudes beyond a principal surface of the piezoelectric substrate; forming a semiconductor substrate having a conductive receiving feature and a semiconductor device electrically connected thereto; aligning the conductive contact structure of the piezoelectric substrate with the conductive receiving feature of the semiconductor substrate; and bonding the piezoelectric substrate with the semiconductor substrate such that the conductive contact structure is in contact with the conductive receiving feature.
