  • Publication number: 20240088095
    Abstract: A method for forming a chip package structure. The method includes bonding first connectors over a front surface of a semiconductor wafer. The method also includes dicing the semiconductor wafer from a rear surface of the semiconductor wafer to form semiconductor dies and mounting first and second semiconductor dies in the semiconductor dies over a top surface of the interposer substrate. The method further forming an encapsulating layer over the top surface of the interposer substrate to cover the first semiconductor die and the second semiconductor die. A first sidewall of the first semiconductor die faces a second sidewall of the second semiconductor die, and upper portions of the first sidewall and the second sidewall have a tapered contour, to define a top die-to-die distance and a bottom die-to-die distance that is less than the top die-to-die distance.

  • Publication number: 20160141928
    Abstract: A rotor structure of interior-permanent-magnet motor includes an iron core member and multiple permanent magnets embedded in the iron core member in the form of a spoke. One end of each magnet near the curvature center of the iron core member is positioned in the space of a corresponding end socket. The space of the end socket restricts the path of the magnetic lines of the magnet and concentrates the magnetic lines to increase the magnetic flux density and enhance the counter potential, whereby the thrust is increased.
