Description of the Related Art A multi-chip module for mounting a semiconductor chip which is required to operate at high speed, such as for a large-scale computer or an image processing apparatus, is generally shown in FIG. The configuration shown in the plan view is adopted. That is, the ceramic multilayer wiring board 1

成する実装回路装置の歩留まりや信頼性に問題がある。However, in the multi-chip module having the above structure, the following inconvenient problems are recognized. That is, since the number of input / output terminals 6 led out from the ceramic multilayer wiring board 1 is as large as about 400 and the pitch formed / arranged is about 2.54 mm, the input / output terminals 6 occupying the ceramic multilayer wiring board 1 Inevitably, the surface area for deriving the multi-chip module will increase, leading to an increase in the size of the multi-chip module. As a means for avoiding the increase in the size of the multi-chip module, it has been attempted to narrow the lead-out / arrangement pitch of the input / output terminals 6. Raise new issues during the implementation stage of. That is, in order to cope with the narrowing of the pitch of the input / output terminals 6, it is not only necessary to form through holes for insertion on the printed wiring board at a narrow pitch, but also the input / output terminals 6 are formed on the through holes formed at a narrow pitch. It is also difficult to insert and solder, and there is a problem in the yield and reliability of the mounted circuit device that constitutes it.

Is desirable. In response to such a demand, it is known to mount a multi-chip module on a printed wiring board via a socket, but as described above, the number of input / output terminals 6 is 400.
If the number of pins is increased to about this number and the pitch is narrowed, the mechanism or structure of the socket becomes complicated and the occupied area also increases, resulting in a large-sized mounted circuit device (system). There is a problem of doing.
