My CRC handbook says silicon melts at 1410 C. (If it was much easier, Intel for instance would be in big trouble). So I doubt that it was liquid silicon you heard about. Also, if it was a silicone that was meant (that final e often gets lost), those materials can be liquid, but they are also insulating. So the report on liquid silicon interconnects is quite puzzling.
