There is provided a conductive sintered layer forming composition and a conductive sintered layer forming method that can lower heating temperature and shorten heating time for a process of accelerating sintering or bonding by sintering of metal nano-particles coated with an organic substance. The conductive sintered layer forming composition may be obtained by utilizing a phenomenon that particles may be sintered at low temperature by mixing silver oxide with metal particles coated with the organic substance and having a grain size of 1 nm to 5 μm as compared to sintering each simple substance. The conductive sintered layer forming composition of the invention is characterized in that it contains the metal particles whose surface is coated with the organic substance and whose grain size is 1 nm to 5 μm and the silver oxide particles.
摘要:
A semiconductor device which uses a semiconductor element having main current input/output electrodes, one and the other of which are extended up to a one surface and a remaining surface of a semiconductor chip respectively for causing one of the input/output electrodes to be contacted with a conductive layer of a insulating substrate, whereby the semiconductor element is supported on or above the insulating substrate. A conductive strip which is made of a composite material of carbon and aluminum or a composite material of carbon and copper is used for connection between the remaining input/output electrode of the semiconductor chip and the conductive layer of the insulating substrate.
