Abstract:
An apparatus for cleaning semiconductor substrates or other items, comprising:a housing having a wall with an interior surface facing the interior of the housing and an exterior surface facing outwardly from the housing;a vibrator coupled to said interior surface for transmitting vibration through said wall;a probe made of a material which efficiently transmits vibration energy, said probe having one end coupled to said exterior surface so that the vibration transmitted through said wall is transmitted into the probe;said housing being a good thermal conductor so that the heat generated by the vibrator is conducted away from the vibrator through the housing; anda heat transfer member snugly fitting within side walls of said housing, said member having an exterior groove that faces the sidewall of said housing so that the groove in combination with the surrounding sidewall of the housing creates a cooling passage through which coolant may be conducted to conduct heat away from the housing.
