摘要:
The invention is directed to improvement of reliability of a semiconductor device having penetrating electrodes by preventing a protection film and an insulation film peeling. A peeling prevention layer for preventing an insulation film and a protection layer peeling is formed in corner portions of the semiconductor device. The peeling prevention layer can increase its peeling prevention effect more when formed in a vacant space of the semiconductor device other than the corner portions, for example, between ball-shaped conductive terminals. In a cross section of the semiconductor device, the peeling prevention layer is formed on the insulation film on the back surface of the semiconductor substrate, and the protection layer formed of a solder resist or the like is formed covering the insulation film and the peeling prevention layer. The peeling prevention layer has a lamination structure of a barrier seed layer and a copper layer formed thereon when formed by an electrolytic plating method.

The invention is directed to a semiconductor device having a penetrating electrode and a manufacturing method thereof in which reliability and a yield of the semiconductor device are enhanced. A semiconductor substrate is etched to form a via hole from a back surface of the semiconductor substrate to a pad electrode. This etching is performed under an etching condition such that an opening diameter of the via hole at its bottom is larger than a width of the pad electrode. Next, a second insulation film is formed on the back surface of the semiconductor substrate including in the via hole 16, exposing the pad electrode at the bottom of the via hole. Next, a penetrating electrode and a wiring layer are formed, being electrically connected with the pad electrode exposed at the bottom of the via hole 16. Furthermore, a protection layer and a conductive terminal are formed. Finally, the semiconductor substrate is cut and separated in semiconductor dies by dicing.

An intake system cover for a vehicle is mounted in an engine compartment to cover a reservoir tank that stores coolant for an engine. The intake system cover for the vehicle is formed with a light introduction opening for introducing light to be directed toward a liquid level gauge at a side of the reservoir tank. The visibility of the liquid level of the reservoir tank at the liquid level gauge is improved.
摘要:
A resin molding is made by integrally joining a first resin molded part configured a concave portion and a second resin molded part configured a convex portion so that the concave portion and the convex portion are mated together. The resin molding includes a cavity that is in communication with the convex portion and the concave portion when the convex and concave portions are mated into each other, and a joining resin filled into the cavity. The first and second molded parts and the joining resin are composed of the same resin or similar resins.
摘要:
The invention provides a method of manufacturing a semiconductor device which achieves high reliability and high yield as well as high production efficiency. Back surface grinding (back grinding) is performed to a semiconductor substrate to thin the semiconductor substrate. A damaged layer formed by the back surface grinding is not removed at this time, and a photoresist layer is selectively formed on the back surface of the semiconductor substrate. The semiconductor substrate is then etched using the photoresist layer as a mask to form a via hole. The photoresist layer is then removed with the semiconductor substrate still placed in an etcher used in the etching process subsequently after the formation of the via hole. In this manner, the etching process and the next ashing process are performed sequentially in one apparatus. Then a process of removing the damaged layer on the back surface of the semiconductor substrate and a process of smoothing the sidewall of the via hole are simultaneously performed subsequently after the ashing process in the same apparatus.

摘要:
A thermal printer has a main body, a cover body, a hinge mechanism, a first locating mechanism, and a second locating mechanism. At the time of a shift from a second state where the cover body is opened with respect to the main body to a first state where the cover body covers the main body, the first locating mechanism locates a first platen roller of the cover body with respect to a first thermal head of the main body, and arranges a second thermal head of the cover body in the vicinity of a second platen roller of the main body. The second locating mechanism locates the second thermal head arranged in the vicinity of the second platen roller by the first locating mechanism with respect to the second platen roller of the main body.
