An ultrasonic waterjet apparatus (10) has a mobile generator module (20) and a high-pressure water hose (40) for delivering high-pressure water from the mobile generator module (20) to a hand-held gun (50) with a trigger and an ultrasonic nozzle (60). An ultrasonic generator in the mobile generator module (20) transmits high-frequency electrical pulses to a piezoelectric or magnetostrictive transducer (62) which vibrates to modulate a high-pressure waterjet flowing through the nozzle (60). The waterjet exiting the ultrasonic nozzle (60) is pulsed into mini slugs of water, each of which imparts a waterhammer pressure on a target surface. The ultrasonic waterjet apparatus (10) may be used to cut and de-burr materials, to clean and de-coat surfaces, and to break rocks. The ultrasonic waterjet apparatus (10) performs these tasks with much greater efficiency than conventional continuous-flow waterjet systems because of the repetitive waterhammer effect A nozzle with multiple exit orifices or a rotating nozzle (76) may be provided in lieu of a nozzle with a single exit orifice to render cleaning and de-coating large surfaces more efficient. A water dump valve (27) and controlling solenoid are located in the mobile generator module (20) rather than the gun (50) to make the gun lighter and more ergonomic.

A blocking plate 3 is disposed opposing a substrate W which is held by plural chuck pins 17 and a processing liquid is supplied from a processing liquid nozzle 5 to a space SP between the front surface Wf of the substrate and an opposed surface 3a of the blocking plate 3, whereby the processing liquid attains the liquid-tight state. While the liquid-tight state with the processing liquid is maintained, the substrate W and the blocking plate 3 rotate. In this condition, a liquid (pure water) to which ultrasonic vibration has propagated is injected from an ultrasonic nozzle 7 approximately perpendicular to a side wall surface 3b of the blocking plate 3. While the ultrasonic vibration spreads inside the blocking plate 3 along the horizontal direction, some vibrational waves spread uniformly and widely from the opposed surface 3a to the processing liquid attaining the liquid-tight state and vibrate the processing liquid. This prevents concentration of the vibrational energy at the front surface Wf, which makes it possible to uniformly process the substrate W while suppressing damage to the substrate W.
