Latest Patents
One of Sekine's latest patents is for a semiconductor device having a thermal stress resistance structure. This innovation provides a high reliability electric power control semiconductor device with a prolonged product lifetime. It successfully suppresses warping of the metal support plate or the metal heat dissipation plate due to thermal stress during bonding. This prevents the occurrences of cracks and gaps in the brazing fillers in the bonded layers between the metal heat dissipation plate or the metal support plate and the insulation plate. The semiconductor device comprises semiconductor elements, a metal heat dissipation plate, a thermal stress buffer, an insulation plate, and a metal support plate. Notably, at least one of the metal heat dissipation plate and the metal support plate comprises a copper alloy with a softening temperature of 350°C or more.
Another significant patent is for a semiconductor module with an improved heat sink and insulation plate. This module features heat sink plates and an insulating plate laminated under the semiconductor chips. The thickness of the support base plate is set to be 2.5 times the thickness of the insulating plate, which is the maximum thickness among the laminated components. This design balances the thermal fatigue lives of the solder layers, thereby prolonging the life of the entire semiconductor module.
