Abstract: This invention relates to a radial array ultrasound endoscopic probe and its manufacture method and a fixing and rotating device. The probe comprises: a metal cylinder located at the center; a plurality of piezoelectric elements which are cut from piezoelectric ceramic or single crystal rings and arranged around the metal cylinder, said piezoelectric elements and said metal cylinder being provided with a backing material layer for absorbing sound therebetween, said piezoelectric elements being covered with a matching material layer on the outer side thereof, and said piezoelectric elements are filled with decoupling material therebetween; a plurality of coaxial cables correspondingly connected with the plurality of piezoelectric elements; and a circular lattice in a gear shape which sleeves over said metal cylinder and functions to arrange and separate the coaxial cables.

Abstract: In a process for fabricating a nano-floating gate memory structure, a substrate and a nanocluster source are firstly provided. The nanocluster source is activated for generating a beam of nanoclusters towards the substrate, and at least part of the nanoclusters are received atop the substrate. Thereby, a plurality of nanoclusters of controllable size are formed atop the substrate.
