Keeping Block Copolymers in Line Could Lead to Smaller Microchips

Keeping Block Copolymers in Line Could Lead to Smaller Microchips

In an effort to keep Moore’s Law going, a team of engineers from MIT, the University of Chicago, and the Argonne National Laboratory has developed a technique to make microchip wire patterns tinier. They’ve accomplished this by making those patterns assemble themselves from a particular type of polymer. With this method, called directed self-assembly , the resulting features are one-quarter the size of features made using today’s chip patterning techniques. Because the technique relies on several tools already commonly used in semiconductor manufacturing, the engineers believe it could easily integrate into the fabrication process. This research, detailed last week in Nature Nanotechnology , resulted in chip features with a pitch dimension—the distance between the midpoint of any two features—of 18.5 nanometers. Chips in production today are capable of smaller, but this wa...
