Abstract
The present disclosure provides a semiconductor cleaning system. The cleaning system includes a chamber to retain a cleaning solution, and a gigasonic frequency generator. The gigasonic frequency generator is configured to generate an electrical signal corresponding to a range of gigahertz frequencies. A transducer is configured to transform the electrical signal to a mechanical wave of pressure and displacement that propagates through the cleaning solution with oscillations within the range of gigahertz frequencies.
