A semiconductor device provided with a filled tetrahedral semiconductor is
formed by introducing impurity atoms S for substituting the component
atoms of sites of lattice points and impurity atoms I to be inserted into
interstitial sites of a host semiconductor where component atoms are
bonded to form a tetrahedral bonding structure. Such a semiconductor
device is made to show a high mobility level and a high current drive
force as a semiconductor substance where impurity atoms S are made to
have a valance electron agreeing with that of the component atoms of the
host semiconductor as a result of charge transfer between impurity atoms
S and impurity atoms I and impurity atoms I are bonded in a state of
showing an electronic arrangement of a closed shell structure is used as
channel material.
