Abstract: A method for manufacturing a semiconductor device in which probes and the layout of the electrode pads of a test element group (TEG) are associated is provided. 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. Thus, it is necessary to associate the probes and the layout of the electrode pad. According to the method, 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 is provided.

Abstract: An extracellular potential measurement device includes multiple insulating films each of which is made from an electric insulating material, the insulating films being stacked and bonded to each other; and multiple electrode wires each of which is made from an electroconductive material, the electrode wires being arranged in multiple heights. Each of the electrode wires is interposed between an upper insulating film and a lower insulating film. Each of the insulating films, except for a lowermost insulating film, has an opening penetrating the insulating film. The opening in a lower insulating film has a size that is less than that of the opening in an upper insulating film, the openings in the insulating films being overlapped to form a recess having a size reducing downward, the recess being adapted to store a collection of cells. Each of the electrode wires has an end that is located near an opening in an insulating film that is immediately below the electrode wire, the ends being exposed in the recess.

Abstract: A microfluidic chip includes a flow passage plate, a flat plate, and an annular seal. In the flow passage plate, a recess forming a flow passage for liquid and a communication hole communicating with the recess are formed. The flat plate is stacked on or under the flow passage plate to close the recess for defining the flow passage. In the flat plate, a communication through-hole communicating with the recess is formed. The annular seal is located on, or formed on, an outer surface of at least one of the flow passage plate and the flat plate, the annular seal surrounding at least one of the communication hole and the communication through-hole. The annular seal is made of an elastomer.

Abstract: A cell capture apparatus includes a cell separation unit having a flat plate shape and a cell capture unit having a flat plate shape located therebelow. A liquid sample and a carrier liquid flow in a cell-separation flow passage of the cell separation unit.
