Abstract: Various embodiments of the present disclosure are directed towards a shared frontside pad/bridge layout for a three-dimensional (3D) integrated circuit (IC), as well as the 3D IC and a method for forming the 3D IC. A second IC die underlies the first IC die, and a third IC die underlies the second IC die. A first-die backside pad, a second-die backside pad, and a third die backside pad are in a row extending in a dimension and overlie the first, second, and third IC dies. Further, the first-die, second-die, and third-die backside pads are electrically coupled respectively to individual semiconductor devices of the first, second, and third IC dies. The second and third IC dies include individual pad/bridge structures at top metal (TM) layers of corresponding interconnect structures. The pad/bridge structures share the shared frontside pad/bridge layout and provide lateral routing in the dimension for the aforementioned electrical coupling.

Abstract: An injection mold includes a first mold part (10), a second mold part (50) mating with the first mold part, a sliding block (20), a cam actuator (30), and a rack (40). The sliding block is movably disposed on the first mold part. The cam actuators resist the sliding block for driving the sliding block to move along the first mold part. The rack is fixed to the second mold part for actuating the cam actuator.

Abstract: A mold apparatus (200) includes an upper mold (40) and a lower mold (50). The upper mold includes an upper guide sleeve (42), an upper mold seat (44), and an upper mold core (46). The lower mold includes a lower guide sleeve (52), a lower mold seat (54) and a lower mold core (56). The upper guide sleeve has a hole (422) defined thereof. The upper seat has an aperture (442) defined thereof. The upper mold seat is fixed below the upper guide sleeve. The lower guide sleeve has a hole (522) defined thereof. The lower seat has an aperture (542) defined thereof. The lower mold seat is fixed on the lower guide sleeve.

Abstract: A mold locking device (10) includes a leader pin (11) and a leader pin bushing (12). The leader pin includes at least one receiving hole (111) defined in an outer surface thereof and at least one spring-loaded ball bearing (112) received in the at least one receiving hole. The spring-loaded ball bearing includes a coil spring (112a) and a ball bearing (112b). The coil spring has one end connected with the leader pin and the other end connected with the ball bearing. A portion of the ball bearing extends beyond the outer surface of the leader pin. The leader pin bushing is used for insertion of the leader pin therein. The leader pin bushing further includes a groove (121) defined in an inner surface for receiving the portion of the at least one spring-loaded ball bearing. A mold (1) is also provided. The mold includes a male mold part (20), a female mold part (30) and the above-described mold locking device.
