Will 7nm And 5nm Really Happen?


Today’s silicon-based finFETs could run out of steam at 10nm. If or when chipmakers move beyond 10nm, IC vendors will require a new transistor architecture. III-V finFETs, gate-all-around FETs, quantum well finFETs, SOI finFETs and vertical nanowires are just a few of the future transistor candidates at 7nm and 5nm. Technically, it’s possible to manufacture the transistor portions of the... » read more

Challenges Mount For Interconnect


By Mark LaPedus There are a plethora of chip-manufacturing challenges for the 20nm node and beyond. When asked what are the top challenges facing leading-edge chip makers today, Gary Patton, vice president of the Semiconductor Research and Development Center at IBM, said it boils down to two major hurdles: lithography and the interconnect. The problems with lithography are well documented.... » read more
