  • Patent number: 10689550
    Abstract: A composition exhibits excellent heat resistance and mounting reliability when bonding a semiconductor power element to a metal lead frame, which is also free of lead and thereby places little burden on the environment. An electrically conductive composition contains at least a sulfide compound represented by R—S—R? (wherein R is an organic group containing at least carbon; R? is an organic group that is the same as or different from R; and R and R? may be bonded to each other to form a so-called cyclic sulfide) and metal particles containing at least Cu, Sn or Ni as its essential component. Further, a conductive paste and a conductive bonding film each are produced using the electrically conductive composition. A dicing die bonding film is obtained by bonding the conductive bonding film with an adhesive tape.
