Abstract: A structure of an under bump metallization and a method of forming the same are provided. The under bump metallization has a redistribution via hole, viewed from the top, in a round shape or a polygon shape having an angle between adjacent edges greater than 90°. Therefore, the step coverage of the later formed metal layer can be improved.

Abstract: The present invention provides a firefly container, comprising transparent outer walls and air holes. After putting nutrients, water, shelters, and matrixes into the viewer, fireflies can be allowed to live in it. Moreover, if a handling device is installed on the present invention, it can be used as a “firefly lantern” and provides edutainmental functions.

Abstract: The present invention provides an easily storing, transporting and displaying plant tissue set, comprising a displaying shelf, and at least one plant-tissue-culturing tube, wherein the displaying shelf has concavities at the bottom or hollow designs to hold tubes. The displaying shelf is designed in a stairs shape which makes the bottom of every tube be irradiated by light, so plant tissues can be exposed to enough light. In addition, the whole package can be easily unfolded and refolded into a displaying mold. This present invention provides a way to displaying the growth process of plants, and it is educative and enjoyable.
