Abstract: PURPOSE:To enhance reliability of an electrical connection and to realize a fine connection by a method wherein a semiconductor element is connected electrically via a superelastic body material and the superelastic body material is formed by a vacuum deposition operation or the like. CONSTITUTION:A film of a superelastic body material is formed at a connection part of a semiconductor element 1; a bump structure is formed; its bump 7 is used as a connection point and is pressurized; a connection is obtained. The superelastic body material is a metal whose elastic strain is 0.5% or higher; the connection point is formed of it by a vacuum deposition operation, a sputtering operation or a CVD operation. The superelastic body material is used for a part which is subjected to a thermal strain in the semiconductor element 1; a deformation is repeated in an elastic range even against a repetitive strain. Accordingly, it is possible to obtain the bump structure which follows an external strain flexibly; the superelastic body material can be formed highly accurately as a bump material. Thereby, it is possible to obtain a semiconductor connection of high reliability.

Abstract: PURPOSE:To protect active data on a data bus which is apt to be affected at the time of disconnection and insertion by controlling the power of a slave processor by a master processor. CONSTITUTION:Before a slave processor (#1) 2 is disconnected, a typewriter 15 is operated to send a power-off signal from a master processor 1 through a control line (#1) 12 and the power of a bus driver/receiver (#1) 6 is turned off. Consequently, the slave processor (#1) 2 is completely disconnected from the system. When functions are restored after the slave processor (#1) 2 is inserted again, the typewriter 15 is operated to send a power-on signal from the control line (#1) 12 and the power of the bus driver/receiver (#1) 6 is turned on, and thereby, the slave processor (#1) 2 is returned to the system. Thus, active data on a data bus 5 is not affected even if the power of the whole of the system is turned on.
