CONSTITUTION:A lower end contactor of a rotary terminal 1 having a knob at its upper end is brought into contact with wirings 2 on a semiconductor chip 4, its columnar part is buried rotatably in a resin package 7, a knob of an upper end protrudes out of the package, and rotated here. A wiring pattern made of a central circular wiring terminal 9a and a ringlike resistor 9b surrounding the terminal 9a is formed of part of wirings on the chip 4, and a resistance value is finely regulated by rotating the rotary terminal. A pattern made of a central circular wiring terminal 10a and a plurality of terminals 10b extending radially to surround the terminal 10a is formed, and circuit wirings in the chip for connecting the plurality of terminals can be switched by operating the rotary terminal.

    • PURPOSE:To improve the dampproof property of the semiconductor device having a multilayer interconnection structure by a method wherein the guide to be used for positioning of the second layer wiring and the through hole of the second layer insulating film and the second wiring are formed simultaneously. CONSTITUTION:A semiconductor element region 2 is formed on the surface of a semiconductor substrate 1, and the first layer wiring 3 is formed extending to an SiO2 film 10. The first layer insulating film 4 of SiO2 or PSG is formed, and a concavity 12 is provided at the position of a guide together with a through hole 11 by performing an etching. Aluminum is vapor-deposited, the second layer wiring 5 is formed by patterning and, at the same time, a guide 7 is formed on the concavity 12. The second layer insulating film 6 of SiO2 or PSG is formed, and a hole 18 with which the guide 7 will be exposed is provided. When moisture 9 is infiltrated through the hole 18, the guide 7 is positioned on the oxide film 10, and the second layer wiring 5 is located on a different levelled interlayer insulating film 4, and this prevents the infiltration of the moisture 9, thereby enabling to improve the dampproof property of the semiconductor device for the wiring.

    • PURPOSE:To avoid projection of a semiconductor device from a mounting board by inserting an electronic device into a containing recess made in a mounting board body 1 and connecting the electronic device electrically and mechanically with a contact formed in the containing recess. CONSTITUTION:A semiconductor integrated circuit is fabricated in a semiconductor device 40 which is mounted on a board 11 to constitute a mounting structure 10. The body 12 of the mounting board 11 is provided with a containing hole 13 and an inner lead 14 is projecting from the inner periphery thereof. Each inner lead 14 is connected electrically with the outside of the containing hole 13 through a multilayer wiring 15 formed in the body 12. Outer terminals 16 for connecting the mounting board 11 with an external electronic device is formed on the surface of the body 12 and connected electrically through the multilayer wiring 15. Consequently, the semiconductor device 40 can be mounted on the mounting board without projecting from the surface of the body 12 and thereby the mounting structure 10 can be made thin.

    • PURPOSE:To cool a semiconductor device forcibly and effectively without consuming power by disposing a fan, comprising members deformable depending on the temperature variation, such that the members respond to the heating of semiconductor device. CONSTITUTION:Upon operation of an IC 1 mounted on the surface of a printed wiring board 5, the IC 1 is heated and the temperature thereof rises. The heat 7 is emitted from a package 2 and transmitted through an adhesive layer 14 to the base 12 thence transmitted to a large number of fins (temperature sensitive deformable members) 13 of a fan 10 and dissipated effectively therefrom. When the atmosphere having raised temperature surrounds the group of fins 13 and the temperature thereof reaches a preset level, the fins 13 are deformed into a previously stored shape. Since energy is consumed at the time of deformation, the temperature of the fins 13 lowers. Furthermore, the fins 13 are deformed to swing a fan thus producing a wind 8. Consequently, the atmosphere around the group of fins 13 is exchanged and the fins 13 are cooled.
