Abstract
An electro acoustic filter component with improved acoustic and/or electro acoustic performance is provided. The component comprises a piezoelectric material (PM) the sides of which are plane and preferably free from chipping defects. The piezoelectric material may be arranged above a carrier substrate (CS). A functional layer (FL) with plane sides may be arranged above an electrode structure (ES) as trimming, TCF or passivation layer. In the manufacturing method the piezoelectric material and the functional layer are removed from the dicing line, such that no chipping occurs for these layers.
