  • Publication number: 20210048450
    Abstract: As a semiconductor device is miniaturized, a scribe area on a wafer also tends to decrease. Accordingly, it is necessary to reduce the size of a TEG arranged in the scribe area, and efficiently arrange an electrode pad for probe contact. Therefore, it is necessary to associate probes and the efficient layout of the electrode pad. The purpose of the present invention is to provide a technique for associating probes and the layout of the electrode pads of a TEG so as to facilitate the evaluation of electrical characteristics. According to a method for manufacturing a semiconductor device of the present invention, the above-described problems can be solved by providing a layout of a TEG electrode pad corresponding to a plurality of probes arranged in a fan shape or probes manufactured by Micro Electro Mechanical Systems (MEMS) technology.
