摘要:
A semiconductor device has a semiconductor chip, a first insulating film and an inductor. The semiconductor chip includes an integrated circuit formed on the main surface of the chip and a plurality of pad electrodes formed on the main surface of the chip and electrically connected to the integrated circuit. The first insulating film of an insulating resin material is formed on the main surface of the semiconductor chip, covers the integrated circuit, and includes a plurality of contact holes provided on the respective pad electrodes. The inductor is formed on the inductor formation region of the first insulating film, and both terminals of the inductor are connected to the pad electrodes through the contact holes, respectively. The inductor formation region of the first insulating film is formed thicker than a portion of the first insulating film around the contact hole.

A resin casing of a box-like configuration has side walls, a bottom wall and a plurality of partition walls. Each partition wall has two opposite end portions tapered, at which the partition wall is integrally formed with the side wall. Thus, the cooling speed is made constant at every portion in the resin casing to avoid shrinkage marks and unwanted raised lines.

摘要:
A three-dimensional object-forming method for forming an object of a three-dimensional shape with photosetting resin, includes the following steps. The desired three-dimensional shape is represented by a set of data related to sectional shapes of the three-dimensional shape cut at predetermined intervals distance of. The laser light is scanned, from above a tank containing liquid of photosetting resin not yet hardened, outward around a predetermined point of each sectional shape in a manner to trace similar figures to an arbitrary shape, to thereby to set a surface of a resin layer in a shape corresponding to one sectional shape. The set resin layer is sunk into the liquid of the photosetting resin not yet hardened by a distance of a cross section. A plurality of the set resin layers of the photosetting resin is laminated by repeating the scanning and sinking steps on the basis of the set of data. The laser light can be scanned at predetermined intervals of distance and in parallel to a direction of each sectional shape and then the desired number of the set resin layers are rotated so that the scanning directions of the resin layers are different from each other.
