Manufacturing Bits: July 10


Ruthenium interconnects Imec has developed a process to enable ruthenium (Ru) interconnects in chips at 5nm and beyond. Ru is one of several candidates to replace traditional copper as the interconnect material in chips. The interconnects, which reside on the top of the transistor, consist of tiny copper wiring schemes that transfer electrical signals from one transistor to another. The int... » read more

Dealing With Resistance In Chips


Chipmakers continue to scale the transistor at advanced nodes, but they are struggling to maintain the same pace with the other two critical parts of the device—the contacts and interconnects. That’s beginning to change, however. In fact, at 10nm/7nm, chipmakers are introducing new topologies and materials such as cobalt, which promises to boost the performance and reduce unwanted resist... » read more

Manufacturing Bits: June 3


World’s thinnest TFTs The U.S. Department of Energy’s Argonne National Laboratory has devised the world’s thinnest flexible, 2D thin-film transistors (TFTs). The transistors are just 10 atomic layers thick. TFTs are typically used in screens and displays. In the lab, Argonne researchers fabricated the TFTs on both a conventional silicon platform and a flexible substrate. [caption i... » read more
