Abstract
The physics of megasonic cleaning is investigated. A novel particle re moval mechanism is analyzed, and the relevant quantities are evaluated . It is shown that the megasonic removal force scales as the cube of t he particle diameter, and that megasonic cleaning technology cannot re move particles of 0.1 mu m and smaller. Therefore, megasonic cleaning is unlikely to be a viable technology for manufacturing devices whose linewidth is below 0.35 mu m.
