A semiconductor device has a temporary carrier. A semiconductor die is oriented with an active surface toward, and mounted to, the temporary carrier. An encapsulant is deposited with a first surface over the temporary carrier and a second surface, opposite the first surface, is deposited over a backside of the semiconductor die. The temporary carrier is removed. A portion of the encapsulant in a periphery of the semiconductor die is removed to form an opening in the first surface of the encapsulant. An interconnect structure is formed over the active surface of the semiconductor die and extends into the opening in the encapsulant layer. A via is formed and extends from the second surface of the encapsulant to the opening. A first bump is formed in the via and electrically connects to the interconnect structure.

POWER SEMICONDUCTOR MODULE WITH SHORT-CIRCUIT FAILURE MODE

A description is given of a power semiconductor module 10 which can be transferred from a normal operating mode to an explosion-free robust short-circuit failure mode. Said power semiconductor module 10 comprises a power semiconductor 1 having metallizations 3 which form potential areas and are separated by insulations and passivations on the top side 2 of said power semiconductor. Furthermore, an electrically conductive connecting layer is provided, on which at least one metal shaped body 4 which has a low lateral electrical resistance and is significantly thicker than the connecting layer is arranged, said at least one metal shaped body being applied by sintering of the connecting layer such that said metal shaped body is cohesively connected to the respective potential area. The metal shaped body 4 is embodied and designed with means for laterally homogenizing a current flowing through it in such a way that a lateral current flow component 5 is maintained until this module switches off in order to avoid an explosion, wherein the metal shaped body 4 has connections 6 having high-current capability. A transition from the operating mode to the robust failure mode then takes place in an explosion-free manner by virtue of the fact that the connections 6 are contact-connected and dimensioned in such a way that in the case of overload currents of greater than a multiple of the rated current of the power semiconductor 1, the operating mode changes to the short-circuit failure mode with connections 6 remaining on the metal shaped body 4 in an explosion-free manner without the formation of arcs.

20170330847 · 2017-11-16 ·

The present technology relates to a camera module capable of reducing the number of steps in the manufacturing process and reducing a black spot failure, a method for manufacturing the camera module, an imaging apparatus, and an electronic instrument. A frame and the rigid flexible substrate are adhered to each other by adhesive formed of thermosetting resin applied on an abutment surface excluding a portion of a range including a bonding section with the FPC drawer unit, thereby forming a vent hole in a site where adhesive has not been applied. At this time, the air of the space between the frame and the rigid flexible substrate is expanded by the heat and discharged from the vent hole. Subsequently, after adhesion is performed with thermosetting resin, reinforcement resin that reinforces the bonding section between the rigid flexible substrate and the FPC drawer unit or that reinforces the bonding section between the rigid flexible substrate and the frame is applied so as to close a portion of the range on which the adhesive has not been applied. This enables omitting the process of closing the vent hole. The present technology can be applied to a camera module.
