摘要:
The present invention relates to a complex type semiconductor device formed by laminating plural semiconductor packages, wherein it comprises: an upper semiconductor package which comprises a substrate for wiring and connecting provided with electrodes for conducting packages on a lower surface in the upper semiconductor package and a principal part of the upper semiconductor package disposed on an upper surface and/or a lower surface of the above substrate and which constitutes a relatively upper part, a lower semiconductor package which comprises a substrate for wiring and connecting provided with electrodes for conducting packages on an upper surface in the lower semiconductor package and a principal part of the lower semiconductor package disposed on an upper surface and/or a lower surface of the above substrate and which constitutes a relatively lower part, a spacer sheet which comprises a space part corresponding to the principal part of the upper semiconductor package and/or the principal part of the lower semiconductor package disposed between the adjacent upper and lower substrates and through holes disposed in a periphery of the above space part and allowing the electrodes oppositely disposed between the substrates to be communicated with each other and which is adhered onto the above substrates and inserted therebetween, connection terminals which are provided in an inside of the through holes in the spacer sheet and which are used for conducting the substrates and connection terminals for external connection which are formed on a lower surface of a substrate for wiring and connecting in a semiconductor package located in a lowermost part and to a production process for the same. The present invention provides a wiring and connecting method by a spacer sheet which ensures an installation space between an upper semiconductor package and a lower semiconductor package in a POP type semiconductor package and prevents short circuit between adjacent connection terminals and which can certainly wire and connect both semiconductor packages, and a complex type semiconductor device of a POP type having a high packaging density prepared is provided by the above method.
摘要:
The present invention provides a spacer sheet for a complex type semiconductor device provided between the semiconductor packages of a complex type semiconductor device formed by laminating plural semiconductor packages, comprising through holes of an array corresponding to electrodes which can be provided onto a substrate of one semiconductor package and which are formed in order to connect and wire one semiconductor package with the other semiconductor package and a space part corresponding to a principal part of the above one semiconductor package mounted on the substrate or a principal part of the other semiconductor package opposed to the substrate and a production process for a complex type semiconductor device in which the above spacer sheet is used. It further provides a wiring and connecting method by using a spacer sheet which satisfies securing of a distance between connection terminals and a narrow pitch at the same time in a POP type semiconductor package and a complex type semiconductor device of a POP type which is increased in a packaging density by the above wiring and connecting method.
