Abstract: In an embodiment, a device includes: a package component including: integrated circuit dies; an encapsulant around the integrated circuit dies; a redistribution structure over the encapsulant and the integrated circuit dies, the redistribution structure being electrically coupled to the integrated circuit dies; sockets over the redistribution structure, the sockets being electrically coupled to the redistribution structure; and a support ring over the redistribution structure and surrounding the sockets, the support ring being disposed along outermost edges of the redistribution structure, the support ring at least partially laterally overlapping the redistribution structure.

Abstract: A memory device and a method for manufacturing the memory device are provided. The memory device includes a stack and a plurality of memory strings. The stack is disposed on the substrate, and the stack includes a plurality of conductive layers and a plurality of insulating layers alternately stacked. The memory strings pass through the stack along a first direction, wherein a first memory string in the memory strings includes a first conductive pillar and a second conductive pillar, a channel layer, and a memory structure. The first conductive pillar and the second conductive pillar respectively extend along the first direction and are separated from each other. The channel layer is disposed between the first conductive pillar and the second conductive pillar. The memory structure surrounds the second conductive pillar, and the memory structure includes a resistive memory material.

Abstract: A three-dimensional printing apparatus includes a platform, a printing head, a filament box, a connecting member and a guiding tube. The connecting member is disposed between the printing head and the filament box, and includes a main body, a first transfer tube, a second transfer tube and a third transfer tube. The first transfer tube, the second transfer tube and the third transfer tube are detachably mounted to the main body. The main body has a first passage, a second passage and a third passage that communicate with each other. The first transfer tube, the second transfer tube and the third transfer tube communicate respectively with the first passage, the second passage and the third passage. The guiding tube is connected to the third transfer tube and the printing head, and communicates with the third transfer tube.
