摘要:
In a stacked semiconductor device which has a plurality of semiconductor chips of desired sizes stacked as one package, a first semiconductor chip is mounted on a flexible printed wiring board provided with external connecting terminals. A printed circuit board is placed and mounted on the first semiconductor chip by flip-chip bonding. A second semiconductor chip is secured onto the printed circuit board. The second semiconductor chip is connected to the flexible printed wiring board by wire bonding. The first semiconductor chip is connected to the flexible printed wiring board by wire bonding via the printed circuit board.

A stacked-type semiconductor device has a reduced overall height and an improved reliability in the mechanical strength of the stacked structure. The semiconductor device also has an improved heat release characteristic. A first interposer has a surface on which first electrode pads are formed and a first semiconductor element is mounted with a circuit forming surface facing the first interposer. A second interposer has a surface on which second electrode pads are formed and a second semiconductor element is mounted with a circuit forming surface facing the second interposer. External connection terminals are provided on a surface of the second interposer opposite to the surface on which the second semiconductor element is mounted. The first and second interposers are electrically connected to each other by conductive members provided therebetween. A back surface of the first semiconductor element and a back surface of the second semiconductor element are fixed to each other by an adhesive.

A plurality of semiconductor devices can be mounted on a mounting board in a three-dimensional structure by stacking one on another with a simple structure. A semiconductor element is mounted on a first surface of an interposer. Electrode pads connected to the semiconductor element are arranged around the semiconductor element on the first surface of the interposer. Protruding electrodes are provided on the respective electrode pads. Through holes are formed in the interposer so as to extend from a second surface opposite to the first surface of the redistribution substrate to the respective electrode pads. The semiconductor element is encapsulated by a seal resin. Each of the protruding electrodes is higher than the sealed portion of the semiconductor element.

A light source device includes: an arc tube having a light emission portion; a first reflection mirror having a substantially concave surface for reflecting light emitted from the light emission portion; and a container which accommodates the arc tube and the first reflection mirror, wherein the container has a duct unit disposed above the arc tube. The duct unit includes a first opening open to the arc tube and disposed at a position shifted toward the traveling direction side from an opening end of the first reflection mirror, a wall portion which forms the edge of the first opening on the side opposite to the traveling direction side as a final end of the duct unit, and an inclined portion disposed in the vicinity of the edge of the first opening on the traveling direction side to bend the flowing direction of the cooling air toward the surface opposite to the surface having the first opening.

摘要:
A laser processing machine includes a work head, a plate-like work working table for processing a plate-like work, a rod-like work working table including a rod-like work holder for processing a rod-like work, and a work area in which the work head is movably provided. The plate-like work working table is provided movably from one side of the work area into the work area. The rod-like work working table is provided movably from another side of the work area into the work area that is opposite side of the one side. According to the laser processing machine, when switching over between a processing of a plate-like work and a processing of a rod-like work, it is needed only to move/evacuate the plate-like work working table and the rod-like work working table to/from the work area, so that the switching-over operation can be easily done.
