Abstract

An AFM probe array with an integrated ultrasonic transducer, comprising: a base, the base is rectangular; a plurality of micro-cantilever beams, which are respectively connected to one side of the base, and each micro-cantilever beam is made with needle tip; multiple ultrasonic transducers, which are respectively fabricated on the back of multiple micro-cantilever beams and / or the back of the base; wherein multiple micro-cantilever beams and multiple ultrasonic transducers form a probe array. The invention integrates the ultrasonic transducer on the probe to solve the internal imaging problem of the sample, and the arrayed probe structure improves the imaging speed.

Description

technical field [0001] The invention relates to the fields of atomic force microscope and ultrasonic detection, in particular to an AFM probe array integrating ultrasonic transducers. Background technique [0002] In 1986, G.Binnig and C.F.Quate successfully developed the atomic force microscope (Atom Force Microscope, AFM). AFM uses the interaction force between atoms to detect the surface morphology of samples, and can realize the atomic-level observation of the surface of conductors, semiconductors and insulator materials. However, the traditional AFM technology cannot detect the structural information inside the sample, and can only perform surface imaging analysis. Therefore, it is necessary to seek other means to detect the internal structural information of the sample. In addition, AFM imaging speed is also very important, and a single AFM probe scanning limits the imaging speed. [0003] Ultrasonic imaging technology uses ultrasonic signals to reflect when they prop...
