  • Patent number: 11715715
    Abstract: A manufacturing method of a metal bump structure is provided. A driving base is provided. At least one pad and an insulating layer are formed on the driving base. The pad is formed on an arrangement surface of the driving base and has an upper surface. The insulating layer covers the arrangement surface of the driving base and the pad, and exposes a part of the upper surface of the pad. A patterned metal layer is formed on the upper surface of the pad exposed by the insulating layer, and extends to cover a part of the insulating layer. An electro-less plating process is performed to form at least one metal bump on the patterned metal layer. A first extension direction of the metal bump is perpendicular to a second extension direction of the driving base.

  • Patent number: 6546522
    Abstract: A method for evaluating design-of-experiment is disclosed. The method includes an optimization method for use in fabricating a semiconductor integration circuit device, wherein the factors are simplified as a single number. The solution procedure is described as the related statement using some cases related about polysilicon deposition and device fabrication process as the sample to illustrate the implementation of this invention. Also, in the embodiment, the present invention is proposed to solve the problem of uncertain preferences from decision-makers. This invention will optimize the weight or the relative importance of each attribute with respect to process conditions and thus does not need any preference from process engineers herein. Therefore, according to the above description, this invention is for solving multiple-criteria problems of very-large-semiconductor-integration (VLSI) manufacturing process.
