摘要:
An object of the present invention is to provide a semiconductor device by packaging a plurality of semiconductor chips three-dimensionally in a smaller thickness, with a smaller footprint, at the lower cost without using any other components and through a simpler manufacturing process of the semiconductor device than with the conventional methods.A flip chip packaging structure is formed by directly connecting a first semiconductor chip (101) reduced in thickness by back grinding and a substrate (105) via a bump electrode (102) to a wiring pattern (106). Also, a second semiconductor chip (103) is formed with an electrode (104) that is higher than the sum of the thickness of the first semiconductor chip (101) and the height of the electrode (102), and the electrode (104) is directly connected to the wiring pattern (106) on the substrate (105), whereby the most-compact three-dimensional semiconductor packaged device is produced.

The present invention provides a circuit board connecting structure enabled to obtain the reliable connection between circuit patterns by restricting the elongation of a flexible base material even when connecting portions are arranged in a face-to-face configuration and are press-contacted with each other.A circuit board connecting structure 10 includes a first circuit board 11, and a second circuit board 12. The circuit board connecting structure 10 is configured so that when a first connecting portion 13 and a second connecting portion 14 are sandwiched by a pair of pressing jigs 18, 19 and are press-contacted with each other, one 23 of first outer dummy terminals is accommodated between columns of ones 33, 33 of second outer dummy terminals, while the other first outer dummy terminal 24 is accommodated between columns of the other ones 34, 34 of the second outer dummy terminals.

摘要:
The invention provides a connecting structure of a circuit board, a connecting part of the circuit board, and an electronic device capable of alleviating a temperature difference between the connecting parts under hot pressure welding. A connecting structure 10 of a circuit board comprises a first circuit board 11 and a second circuit board 12, with a first connecting part 15 and a second connecting part 16 opposedly disposed via an adhesive 13. The first connecting part 15 and the second connecting part 16 are pinched by a pair of pressurizing jigs 20 and subjected to hot pressure welding so that first circuit patterns 17 and second circuit patterns 18 are in contact with each other. In the connecting structure 10 of the circuit board, the first circuit board 11 is a soft base material 21, and a heat-insulating layer 28, having lower thermal conductivity than the soft base material 21, is provided on only a part 27 of the region corresponding to the first connecting part 15 on the rear surface 21B of the soft base material 21.

An information processing apparatus includes a pattern extraction unit, a rule extraction unit, and a reflection information generation unit. The pattern extraction unit is configured to extract an operation pattern of each of users from operation history information obtained from a plurality of devices to be operated, the operation history information at least including information regarding operation histories of the users and device states. The rule extraction unit is configured to extract incorrect operation patterns from the operation patterns extracted by the pattern extraction unit, the incorrect operation patterns being operation patterns caused by incorrect operations performed by the users. The reflection information generation unit is configured to identify a cause of the incorrect operations from types of the incorrect operation patterns and generate, based on the cause of the incorrect operations, reflection information configured to be reflected in functions of the devices to be operated.
摘要:
A small-sized audio signal reproducing apparatus for hearing reproduced audio signals with the aid of a headphone is disclosed. Digitized and compression encoded audio signals, stored in a semiconductor memory, are read out so as to undergo a decoding operation, which is an inverse operation to compression encoding, to reproduce the audio signals, and the reproduced signals are heard by the headphone. The apparatus may be significantly reduced in size and weight as compared to the apparatus in which a tape or a disk is used as the recording medium.
