Claim:
1. An ultrasonic micron precision molding apparatus comprising: an ultrasonic generating module, serving to originate ultrasonic frequency oscillation; a tool of micron precision, disposed at under side of the ultrasonic generating module; and an amplitude transformer, sandwiched between the ultrasonic generating module and the tool, the amplitude transformer having an enlarged engaging section with a first transverse cross-section firmly fixed on the tool, and the amplitude transformer having a second transverse cross-section parallel to the first transverse cross-section, wherein a profile of the amplitude transformer in a three dimensional coordinate system is represented by three rectilinear axis lines named X axis, Y axis and Z axis vertical to each other, and the Z axis is vertical to the first and second transverse cross-sections, wherein a distance from the second transverse cross-section to the tool is longer than a distance from the first transverse cross-section to the tool, and an area of the first transverse cross-section is larger than an area of the second transverse cross-section, after receiving the ultrasonic frequency oscillation from the ultrasonic generating module, the amplitude transformer has an X-axial deformation, a Y-axial deformation and a Z-axial deformation, wherein a numerical value of the X-axial deformation divided by the Z-axial deformation is larger than 0%, but less than 1%, and a numerical value of the Y-axial deformation divided by the Z-axial deformation is larger than 0%, but less than 1%, wherein the ultrasonic generating module comprises an ultrasound controller and a transducer with functions that the ultrasound controller serves to supply electric power together with vibration mode to the transducer while the transducer serves to originate and transfer ultrasonic frequency oscillation to the amplitude transformer.
