Abstract:
1. A semiconductor package comprising: a semiconductor chip having a transmission side film bulk acoustic filter and a reception side film bulk acoustic filter formed at an upper surface of a semiconductor substrate accordingly as a plurality of film bulk acoustic resonators are connected serially and in parallel; a substrate provided with a ceramic body where the semiconductor chip is mounted, a plurality of wire patterns formed at an upper surface of the ceramic body so that the semiconductor chip can be connected thereto by a solder as a flip chip form with an overturned state, and a plurality of conductive ground vias and signal conductive vias connected to the plurality of wire patterns and penetrating the ceramic body; and a sealing layer for sealing the semiconductor chip of the upper surface of the ceramic body for protection from the external environment, wherein the sealing layer is one selected from epoxy or polymer.
