Abstract
Semiconductor equipment includes: a first lead frame having a first semiconductor device; a second lead frame having a second semiconductor device; a thermal resistor for preventing heat transfer from the first lead frame to the second lead frame; and a temperature sensitive device for detecting operational temperature of the first semiconductor device. The first lead frame is separated from the second lead frame by a predetermined distance. The thermal resistor is disposed in a clearance between the first lead frame and the second lead frame. The second semiconductor device controls to restrict operation of the first semiconductor device when the operational temperature of the first semiconductor device is higher than a predetermined temperature.
