Problems solved by technology
However, in this case, for a semiconductor chip having a large stud bump height, the volume of the anisotropic conductive resin interposed between the semiconductor chip and the wiring board becomes large, thereby possibly producing a poor connection so that it is not affected by heat. Lower button tab disengages connection section of terminal block

An electronic device comprising: a semiconductor chip having plural electrode pads on one main surface thereof; a wiring board having plural connection parts; and plural salient electrodes disposed respectively between the electrode pads of the semiconductor chip and the connection parts of the wiring board to provide electrical connections between the two, the salient electrodes being arranged in an array not providing balance of the semiconductor chip with respect to one main surface of the wiring board, the plural connection parts of the wiring board being arranged at a deeper position than one main surface of the wiring board in a depth direction from the one main surface.
Description
technical field [0001] The invention relates to an electronic device and a method for making the device. In particular, the present invention relates to a technology that is effectively applicable to electronic devices employing flip-chip mounting (mounting) technology. Background technique [0002] An electronic device called an MCM (Multi-Chip Module) is known as an electronic device. In an MCM, a plurality of semiconductor chips each including an integrated circuit are mounted on a wiring board to perform an integrated function. Regarding MCMs, it is becoming more and more popular to employ a flip-chip mounting technique in which a semiconductor chip (flip-chip) with raised electrodes formed on electrode pads on a circuit-forming surface is mounted on the terminal block. This is to increase data transfer speed and reduce device size. [0003] Regarding flip chip mounting technology, various mounting methods have been proposed and put to practical use. For example, as...
