According to the present invention, when a semiconductor element having protruding electrodes formed thereon is connected to a circuit board via conductive resin, stable connection is made even when an electrode pitch is small on the semiconductor element. Thus both types of transistors on a single chip or substrate can achieve an enhanced carrier mobility, thereby improving the performance of CMOS devices and integrated circuits. Such a vibratory string tensioned or strained to its superelastic state has improved harmonic and tonal stability characteristics. Each of the transverse passageways terminates at either end in an outlet.
