Described herein is a stacked package according to the present invention, wherein a plurality of tape carriers which seal semiconductor chips, are multilayered in upward and downward directions. In the stacked package, one ends of leads formed over the whole surfaces of each tape carrier are electrically connected to their corresponding connecting terminals of the semiconductor chip. Other ends of the leads are electrically connected to their corresponding through holes defined in the tape carrier. Connecting terminals common to the plurality of semiconductor chips are formed at the same places of the plurality of tape carriers and withdrawn to the same external connecting terminals through a plurality of mutually-penetrated through holes.

A laser beam is irradiated onto a photocurable resin layer formed on an electrode part before rearrangement. By scanning the resin on the periphery of a metal wiring formation area extending from the electrode part before rearrangement to a bump electrode contact area, is cured. As a result, a cured resin part is formed which works as a guide layer and a protection film for protecting the metal wire in which the metal wiring formation area has a hollow shape. Thereafter, the metal wire is formed inside the cured resin part.

A developing apparatus having a container for containing a one component developer, and a rotatable developing roller disposed facing an image bearing member to carry developer from the container to a development zone where it is supplied to an electrostatic latent image carried on an image bearing member. The developing roller includes a metal base member and a resin coating layer thereon in which fine conductive particles are dispersed. The developing roller has a surface including an end region adjacent an end of the roller, and an intermediate region. In the end region, the base member is not roughened and the resin layer is not provided. In the intermediate region, inside the end region, the base member is roughened and is coated with the resin layer. A sealing member is provided for preventing leakage of the developer from the container at the end of the developing roller, the sealing member being faced to the end region of the developing roller.

A thread feeder for sewing machines is disclosed which feeds the thread from one of the bobbins to an automatic threading machine. It includes a movable table over the sewing machine, bobbins mounted thereon, thread tension regulators for adjusting tension to the thread from the bobbin, and feed rollers for feeding the thread from the thread tension regulator to the automatic threading device on a sewing machine. By such an arrangement, threads of different color or material can be fed conveniently one after another in a desired order.

In a semiconductor integrated circuit device, testing pads (209b) using a conductive layer, such as relocation wiring layers (205) are provided just above or in the neighborhood of terminals like bonding pads (202b) used only for probe inspection at which bump electrodes (208) are not provided. Similar testing pads may be provided even with respect to terminals like bonding pads provided with bump electrodes. A probe test is executed by using these testing pads or under the combined use of under bump metallurgies antecedent to the formation of the bump electrodes together with the testing pads. According to the above, bump electrodes for pads dedicated for probe testing may not be added owing to the use of the testing pads. Further, the use of testing pads provided in the neighborhood of the terminals like the bonding pads and smaller in size than the under bump metallurgies enables a probe test to be executed after a relocation wiring process.
