Patents by Inventor Fumito IMURA

Fumito IMURA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10304675
    Abstract: A semiconductor manufacturing system has a series of steps, from manufacturing of a semiconductor on a wafer until packaging, that can be easily linked. A semiconductor chip manufacturing device manufactures a semiconductor chip, and a semiconductor packaging device packages the semiconductor chip by attaching the semiconductor chip to a package substrate which is larger than the wafer. The semiconductor chip manufacturing device includes a PLAD system for loading the wafer into and out of the semiconductor chip manufacturing device through a shuttle which is capable of housing the wafer. The semiconductor packaging device includes a PLAD system capable of loading the package substrate into and out of the semiconductor packaging device through a shuttle which is capable of housing the package substrate. The shuttles have container bodies of a same shape.

  • Patent number: 10163819
    Abstract: A method for manufacturing a surface-mount type package whose face parallel with the semiconductor chip surface has a circular cross-section, is characterized by including at least the following steps in this order: a first step in which a semiconductor chip is bonded onto a circular support substrate; a second step in which the semiconductor chip is sealed with resin; a third step in which the resin covering the pads of the semiconductor chip is removed; a fourth step in which a rewiring layer is formed; and a fifth step in which bumps are formed. The method can provide a surface-mount type package for semiconductor chips which is resistant to failures caused by thermal stress.

  • Patent number: 10163674
    Abstract: An object of the present invention is to provide a circular support substrate that allows for positioning based solely on its outer periphery shape. As a means for solving the problems, a circular support substrate is provided that has at least three chords along its circumference, wherein the chords are provided at positions where they do not run linearly symmetrical to the straight line passing through the center axis of the circular support substrate.
