Abstract: A semiconductor device has a carrier and a semiconductor die disposed over the carrier. A dummy die is disposed over the carrier as well. A first encapsulant is deposited over the semiconductor die and dummy die. The dummy die and a first portion of the first encapsulant is backgrinded while a second portion of the first encapsulant remains covering the semiconductor die. Backgrinding the dummy die fully removes the dummy die while the second portion of the first encapsulant remains covering the semiconductor die. A second encapsulant is optionally deposited over the dummy die prior to disposing the dummy die over the carrier. A conductive pillar is optionally formed over the dummy die prior to depositing the second encapsulant. The carrier is removed to expose an active surface of the semiconductor die. A build-up interconnect structure is formed over the active surface after removing the carrier.

Abstract: An apparatus and a method are provided for controlling a low DC-DC converter (LDC) in an electric vehicle by prioritizing respective controllers, connecting the controllers in series in ascending order according to priority, and determining a command voltage of the LDC on the basis of output voltages of the respective controllers. Accordingly, even when a controller with a highest priority is operating, controllers of lower priority continue operating. Thus, electrical load performance degradation caused by instantaneous overcurrent generated in state transitions is prevented.

Abstract: A method for controlling a relay of an auxiliary battery by a controller includes deciding whether or not a low direct current (DC) to DC converter (LDC) supplies power required in an electronic load in a state of charge (SOC) maintaining mode of the auxiliary battery. As a result of the decision, a turn-on state of the relay in which power of the auxiliary battery is supplied to the electronic load is maintained when the LDC does not supply the power required in the electronic load. As a result of the decision, the relay is turned off so that power of the auxiliary battery is not supplied to the electronic load when the LDC supplies the power required in the electronic load.
