摘要:
A semiconductor device can include a substrate that has a surface. A via structure can extend through the substrate toward the surface of the substrate, where the via structure includes an upper surface. A pad structure can be on the surface of the substrate, where the pad structure can include a lower surface having at least one protrusion that is configured to protrude toward the upper surface of the via structure.
摘要:
An integrated circuit device includes a semiconductor structure, a through-silicon-via (TSV) structure that penetrates through the semiconductor structure and a connection terminal connected to the TSV structure. A metal capping layer includes a flat capping portion that covers the bottom surface of the connection terminal and a wedge-shaped capping portion that is integrally connected to the flat capping portion and that partially covers a side wall of the connection terminal. The metal capping layer may be formed by an electroplating process in which the connection terminal is in contact with a metal strike electroplating solution while a pulse-type current is applied.

摘要:
A semiconductor device manufacturing apparatus and a control method thereof which can shorten the manufacturing term of semiconductor devices are achieved. The semiconductor device manufacturing apparatus includes a plurality of processing apparatuses for taking out and processing semiconductor wafers successively which constitute a process lot, and including a standby port where a lot to be processed following processing of the process lot is put on standby. The semiconductor device manufacturing apparatus further includes a stocker for storing a lot to be transported to the standby port. According to the control method of the semiconductor device manufacturing apparatus, it is predicted when there is no standby wafer left in the processing apparatus in a prediction step. The predicted time is used to set transfer starting time when transfer of the next-processed lot to the standby port is started in a time setting step. A lot to be processed next is selected in a lot selecting step. The next-processed lot is transported to the processing apparatus at or after the transfer starting time in a transfer step.
