摘要:
The semiconductor device includes a substrate, a semiconductor component, and a cap covering the semiconductor component and attached to the substrate. The cap has a top wall, a plurality of side walls 14 extending downward from the top wall and a bottom wall. Opening are provided in the side walls of the cap at corners thereof. Due to the provision of openings, the cap can be manufactured without deformation thereof. Air or liquid can flow into, or out of, the interior of the cap, after the semiconductor deviced is completed.

摘要:
A semiconductor device capable of preventing contact between electrode terminals and a die pad as well as capable of surely performing wire bonding to the electrode terminals. A passive component is formed such that a vertical height of each electrode terminal is higher than that of an element part. More specifically, each cross-sectional area of the electrode terminals is slightly larger than that of the element part. Therefore, an upper part and lower part of each electrode terminal are slightly higher than (project from) the element part. Through an adhesive, the passive component is fixed such that the element part is located on the high position part so as to be nearly parallel to a substrate surface. Further, a part of each electrode terminal (bottom part) is located in each space within concave parts. Thus, a predetermined space is formed between each of the electrode terminals and the die pad.

In a semiconductor chip, a first semiconductor chip 21 is provided on a chip-mounting component 11, and bonding wires 36 connected to electrode pads 21E of the first semiconductor chip 21 are fixed by being covered with a first insulating adhesive 31. A second semiconductor chip 22 is mounted by being stacked on the first semiconductor chip 21, with the first insulating adhesive 31 therebetween. This structure can prevent problems such as breaking and short-circuits of bonding wires of the chip disposed directly on a substrate when another chip is mounted by being stacked.

摘要:
In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the “cancel” state, the transition to the “in-control, inter-vehicle distance control” sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the “in-control, collision alarm” sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the “in-control, collision avoiding control” sub-state, and a collision avoiding control is performed.
