Plastic Toy Could Be Used in Microchip Manufacture

Researchers at Northwestern University (Evanston, IL) have discovered a way to create and mass produce nanoscale patterns using the 1970s children’s toy Shrinky-Dinks, made of flexible plastic sheets. The sheets can be used to produce large-area patterns for applications in solar cells, high-definition displays, and chemical sensors.   Writing nanoscale patterns for modern microchips on large areas of silicon wafers is a time-consuming process, but the newly discovered method enables the patterns to be mass produced inexpensively, the researchers say...
