POTENTIAL NANOELECTRONIC INTEGRATED-CIRCUIT TECHNOLOGIES

We discuss the opportunities for Nanoelectronic devices based on reson ant tunneling to impact integrated circuit (IC) technology. We believe that resonant tunneling diodes (RTDs) integrated with conventional co mpound semiconductor transistors will be the first opportunity for pro ducts. The development of silicon heterostructure technology should pe rmit RTDs to augment CMOS ICs by permitting novel circuit applications that will have speed and functional density advantages. In our view, the most promising avenue for downscaling to exist beyond CMOS will be Quantum Dot IC technology. Numerous challenges for nanotechnology exi st along each step of these paths.
