SAW filter using tetrahedral amorphous carbon and method for manufacturing the same

   
   

Disclosed is an element using a piezoelectric characteristic, and in particular, an SAW filter and a method for manufacturing the same. The SAW filter according to the invention is resistant to input wave of high power by employing ta-C or CNT as an acoustic wave transmission medium. The method for manufacturing the SAW filter according to the invention simplified the manufacturing process and reduced a transmission loss as well noise.
