  • Publication number: 20200309845
    Abstract: The present invention relates to an optimization method for an integrated circuit wafer test, which is applied in an integrated circuit wafer test process. By means of pre-specifying and storing coordinates of a die to be tested on a wafer in a test system, then testing the pre-specified die according to a design map by means of a test process, and adjusting in real time a range of pre-specified coordinates according to a test result of a current die, a desired test coordinate map is finally obtained so as to cover the maximum number of fail dies in an optimized solution, thereby reducing test time, improving testing efficiency, reducing the frequency of testing hardware usage and increasing service life. By means of calculating a suitable coverage number in the present invention, a smaller number of fail chips that reach a package will also be obtained without increasing the cost of the package. At the same time, the number of probe card tests is reduced, and the hardware service life is increased.

  • Publication number: 20200110144
    Abstract: A method for MRI imaging of a subject includes spatially encoding spins in a slice of the subject in orthogonal first and second directions. The encoding includes applying a chirped radiofrequency (RF) pulse concurrently with application of a magnetic field gradient pulse along the first direction. After applying of the RF pulse, a second chirped RF pulse is applied concurrently with application of a second magnetic field gradient pulse, with polarity opposite that of the first gradient pulse. An encoding magnetic field gradient, constant from applying the first RF pulse until the end of applying the second RF pulse, is concurrently applied along the second direction. Following the encoding, a spin signal is measured concurrently with application of a constant readout magnetic field gradient.

    Abstract: A catheter which includes a cutting element having one or more raised elements is provided. The cutting element has a cup-shaped surface at the distal end that may be smooth and continuous except for the raised elements. The raised elements have a surface that tends to direct cut particles of material towards one or more of the axis of rotation of the cutting element, the catheter axis, or a particle collection chamber. In further aspects of the invention, a cutting element oscillates in a direction roughly parallel to the axis of rotation of the cutting element.
