Patent ID: 7679153

Claim:
An electronic component comprising: a semiconductor substrate having a flat first surface and a second surface opposite and parallel to the first surface; a trans-substrate conductive plug that penetrates the semiconductor substrate from the first surface to the second surface; a second member having a third surface that faces and is spaced apart from the first surface; a surface acoustic wave element provided on the third surface of the second member and spaced apart from the first surface of the semiconductor substrate, the surface acoustic wave element being electrically connected to one end of the trans-substrate conductive plug and including a piezoelectric thin film and comb-shaped electrodes contacting the piezoelectric thin film; a glass sealing member directly connected to the semiconductor substrate by a resin-based adhesive layer, the glass sealing member sealing the surface acoustic wave element in a sealed inner space defined between the sealing member, the adhesive layer and the first surface; an integrated circuit which is provided on the second surface of the semiconductor substrate at a position outside of the sealed inner space and is electrically connected to a second end of the trans-substrate conductive plug opposite the one end, and drives and controls the surface acoustic wave element, the integrated circuit including a transistor and a memory element; and a connecting terminal for connecting to an external apparatus, the connecting terminal being provided above the second surface of the semiconductor substrate, wherein at least a part of the trans-substrate conductive plug is provided on a plane parallel to the first surface within an area corresponding to the surface acoustic wave element, and wherein at least a part of the connecting terminal is provided on a plane parallel to the first surface within an area corresponding to the surface acoustic wave element.
