Abstract
An integrated structure of acoustic wave device and varactor comprises an acoustic wave device and a varactor formed on a first part and a second part of a semiconductor substrate respectively. The acoustic wave device comprises an acoustic wave device upper structure and a first part of a bottom epitaxial structure. The acoustic wave device upper structure is formed on the first part of the bottom epitaxial structure. The varactor comprises a varactor upper structure and a second part of the bottom epitaxial structure. The varactor upper structure is formed on the second part of the bottom epitaxial structure. The integrated structure of the acoustic wave device and the varactor formed on the same semiconductor substrate is capable of reducing the module size, optimizing the impedance matching, and reducing the signal loss between the varactor and the acoustic wave device.
