Classification: CPC G | IPC G

Claim 9:
10. An ultrasound acoustic microscopy device comprising:
a carrier for carrying a sample;
a signal generator configured to generate an actuation signal having a frequency of at least 1 GHz to be converted into an ultrasound acoustic signal for transmission;
a scanning head including a cantilever with separate tips for transmitting an acoustic wave into the sample and for receiving acoustic waves reflected from features within the sample, the separate tips comprising:
a transmission tip configured to contact a sample to transmit the ultrasound acoustic signal as an ultrasound acoustic wave into the sample, and
a reception tip, separate from the transmission tip, to contact the sample to receive an acoustic signal resulting from reflections of the ultrasound acoustic wave from within the sample;

a signal processor configured to generate an image signal in response to a sensor signal generated in response to the acoustic signal resulting from reflections received by the reception tip; and
a scanning mechanism configured to displace the scanning head relative to the sample, along a surface of the sample,
wherein the transmission tip and the reception tip are accommodated at mutually different positions on a same surface of the cantilever that is facing in a direction of the carrier,
wherein additionally, an atomic force microscopy (AFM) deflection measurement pad is accommodated on the surface of the cantilever, the AFM deflection measurement pad being arranged symmetrically with respect to the transmission tip and the reception tip.
