A board that includes a flat back face, corresponding to a resin sealing area, and a front face that has projections is provided. The projections are formed of a metal that is integral with the board and include (a) a bonding pad provided in an area surrounded by an area that contacts an upper die, (b) a wiring that is integrated with the bonding pad and which extends to a semiconductor element mounting area, and (c) an electrode provided in one body with the wiring. A semiconductor element is mounted on the semiconductor element area and electrically connected to the bonding pad. The board is placed on a lower die and resin is filled into a space formed by the board and upper die. The board is divided into multiple devices such that the projections are separated by removing the board exposed at the back face of the resin.

Abstract: After a trench 54 is formed in a conductive foil 60, the circuit elements are mounted, and the insulating resin is applied on the conductive foil 60 as the support substrate.

And the interconnects L1 to L3 requisite for the circuit are formed, and can be prevented from slipping because of the curved structure 59 and a visor 58.

Abstract: A method of manufacturing a System In Package (SIP) or Integrated System in Board (ISB) circuit device in which a plurality of circuit elements are covered with and integrally supported by an insulating resin. A user terminal is connected with an ISB server and an ISB mounting factory through a communication network. Specifications to be satisfied by an ISB circuit device desired by a user, such as an external size and terminal information of the ISB and circuit diagram CAD data, for example, are input through the user terminal and transmitted to the ISB server. The ISB server in turn transmits information concerning the due date and cost of the ISB circuit device and also a reliability evaluation result to the user terminal. The ISB server also generates mask data for manufacturing the ISB circuit device based on the input specifications, and transmits the mask data to the ISB mounting factory.

In a circuit module of this embodiment, a laminated sheet to which a pressure sensing element and a circuit element are electrically connected is thinned and allowed to occupy as little space as possible. Thus, the entire circuit module is reduced in thickness and saving of space is realized. Moreover, noise caused by an electromagnetic wave, an electric field and the like is shut off by use of reinforcing plates. Thus, pressure information can be converted into accurate electric signals. Furthermore, noise to the outside from the circuit module of the present invention can be shut off.
